*whips out clipboard
*whips out Bureau of Standards Pub ASTM E2624-15
*adjusts glasses
Well that's true Mr AVE that they use 2 inch fasteners and new grease between runs. That is the universal standard used to insure that all test use the same baseline to testicle different impact guns. IE 3/8, 1/2, 3/4, and 1 inch all use the same test bed for repeatability.
* adjusts glasses
I looked everywhere and haven't found a "1100 lbs ft *tested per ASTM E2624-15" statement anywhere. Am I dumb or just ugly?
AvE or missing a testicle
rigidity, mass, size of fastener, moment of inertia, friction and some more factors play a huge role in impulse drivers. normal torque wrenches on the others hand only need to combat rigidity and friction
maybe they just need to change the testing standards and publish a chart of different size(length and width) fasteners, type of steel and lubrication with achieved torque
that at least will be a better reference
Yes. Real Tool Reviews doesn't say this the actual torque capability. He uses the Skidmore Wilhelm because that is what he thinks the industry uses to make their "nut busting" torque claims. I think he even has a video where he says "nut busting" torque is marketing BS. But he uses the same procedure for all wrenches so it is a valid benchmark for comparison purposes. At least AvE noticed RTR also gives dynamic results with the digital meter.
Real Tool Reviews guy said he contacted one of the tool companies before and that's the bolt setup they use. so he didn't just assume
THIS GUY IS A WEALTH OF KNOWLEDGE, SEE WHAT READING AND STUDYING WILL PRODUCE... THIS GUY'S LITTLE GIRL IS GOING TO BE A GENIUS.....
True fact. The all caps prove it.
On the internet CAPS LOCK is cruise control for cool.
Saw it on the internetz, must be true!
Where as he is technical, she very well could be artistic. That's how I disappointed my Dad 😆
I have to agree with him. I am constantly in awe of you seemingly limitless knowledge combined with the sandpaper gruffness that would make a sailor beam with pride .
The live zero explanation is great. This is what makes the check engine light come on in your cars. It basically informs you that a sensor is reading out of its designed range.
Why all the vids in the wife's sewing room? Is she taking over the shop?
And if so what does she keep in her vice?
yolo swag his stick if he keeps using her room...
She keeps her (fresh) batteries in her vice.
Might be getting too cluttered in the empire of dirt.
Might smell better too. What for the excrement left over from the colostomy bags o juice, could be smelling up the shop by now.

Asking the real questions here
Also worth mentioning is the frequency response. The type of pressure transducer(s) shown, typically have a conditioning circuit and/or ASIC in the device to provide linearization/scaling (such as the 'live zero') and temperature compensation. This type of signal conditioning can lead to slower response times or a dampened output.
taking the wife's batteries...job security.
Yet, making sure the battery company has job security. Bringing balance back to the force.
Twizler Skunk ROFLMFAO
These are the videos I like watching. I'm pretty new to the industry and it's nice hearing things straight from a guy that has actually dealt with the stuff. Keep up the great videos
Great job and a good demonstration. We use pressure transducers all the time in Automotive Diagnostics. We use them in the tailpipe 4 exhaust pulse diagnosis , we'll use them in the spark plug hole for in cylinder testing , vacuum testing, fuel pressure, transmission Etc. It's nice to be able to see your pressure on a scope instead of just a gauge and log voltage over time.
South Main Auto Repair well , at least I liked ypur comment 😄
Haha..and I thought I was the only car tech guy that watched AvE (:
I thought that only a few use these as auto techs
"overpaid guesswork" - love it
In my opinion this is one of the best videos I've seen you post in a while. Using science to call out people's bullshit, excellent! Keep it coming Ave.
This is my absolute-favorite kind of rant -- the kind where you clearly spend a bunch of your valuable time building up supporting data to make the case. This is what keeps me going as I'm stuck behind a desk all day instead of in the shop where I belong.
I think this is one of AvE's best videos. Thumbs up!
Wicked! I love your videos like this. As an Aeromaplane Wrencher, it's these little tricks of troubleshooting that I find valuable as frig!
6:59 Did you just farted into your transducer? :o
How in Gods name did I miss that the first time I watched it?
I assumed I was the only one who caught that. What was I thinking?
had to come up with pressure somehow for the testing
I thought it was because he was blowing so hard he squeezed one out! Had to pause the video I was laughing so hard.
David Taylor me too! 😂 if he blew any harder I am sure his arse hole would have become a transducer!
Good vid, love how the previous vids of the Harbour Freight impact get brought back in to make a point.
Really appreciate when you go over this stuff. I'm an engineering student, and we still have to figure most of this out ourselves. Anytime you want to make a video on a Lego brick, I appreciate it.
Liked in the first few seconds because of the really quite decent description of what a transducer is.
I'm so glad I discovered your channel, besides being very entertaining and funny as hell!, you also teach me quite a bit and I greatly appreciate that!.
Man, I've struggled for years to understand how the wheatstone bridge works in the 3rd and 2nd class power eng books, and just counted myself lucky that I haven't gotten asked on the exams. Best explanation I've seen. Thanks bro
I'm baffled by the amount of information I have learned thanks to your videos. THX AvE !!!!!!
I have sold these before and never really knew what they were used for. Now I know! Thanks uncle bumble frig
and again I learn more from AvE than I ever did a engineering school.
Thanks. You just helped me solve a problem (i.e. making a temp process controller indicate pressure.)
YOU THE MAN.
I have learnt more from watching these videos than I ever did at school. It appears that when those who *can*, teach ... it works.
YESSS! we're on the road to the vidjeo I requested you to make a few months back! Can't wait for the addition of Arduino functionality!
Wow! So much cool lego! Loving the learning AvE!
I appreciate how you used a teaching video to prove that you were right on an otherwise loosely-related topic. 😀
Hats off to you for sorting that all out
I absolutely love the way you teach your hilarious but thorough.
Thanks for this, I'll be using some pressure transducers for data logging in my turbo engine build.
Remember "Thing" from Adam's Family? The first time I saw your videos my sound was muted, and it looked to me like one of Things descendants has themselves a killer CZcams channel. Fixed the sound and now I laugh my ass off regularly- but still think of this as the "Grandson of Thing" channel. Thanks for the knowledge- you're teaching old dogs new tricks.
So useful AvE!!! Cheers
Love how he teaches! I learn a ton.
I love your channel and work brother some of the best lessons I have learned in electronics and home shop dickery I got from you. Hell you, Keith Fenner, Abom79, and John Mills (Doubleboost) have shown me so much as well as This Old Tony and a little bit of Stefan Gottenswinter. Your and Keith's influence helped talk my better half into letting me get a mini lathe, tooling, and other equipment for my shop and house much love and many thanks.
We made a wheatstone bridge into a digital thermometer in an electronics class I took. They're super useful for such a simple thing.
I like the idea of a series on lego parts of industry !
good Lord this video was badass going to have to watch it again
I'm an etech in the oil and gas industry. we run 20000psi transducers on 4-20 ma scale. gotta love the live zero for quick glances!
edutainment at it's finest, AvE keep on Rocken man your vjayos are like sweet molasses in a bitter world :)
Learned a lot,thanks!
love the video im looking forward to the next video
It's my semester exams and my first subject tomorrow is Automated Control Systems...Defining the Laplace transformation just didn't cut it for me and you saved the day! Thanks!
They have computers for that nowadays.
Yeah but I wouldn't stop reading from my books unless you made a video about it!
I use pressure transducers at work for development testing. If you want to data log for longer then the oscope get a Dataq data logger. They have $60 options at about 40kHz and are super easy to use.
Love the rant, now I am going to the shop to do the same, however with a lot more emphasis on sailors slurs.
aw fuck yeah, home from work and AvE posts a vidjeo
Your language reminds me if my German colleagues. I enjoyed your vid. Thanks.
I may or may not have half a dozen 'used good' transducers or regulators in my toolbox at work. I need to set this up!
I have learned more from you and your kunuckee ramblings than I ever did in enginerd school
This is exactly the mad sorcery hacking that I love from this channel. Thanx
You can actually hook those transducers up to a computer mic/line input if you don't have a scope (use a resistor divider and/or potentiometer to bring the voltage down so you don't saturate the line input). If you're not interested in absolute magnitude it works a treat. I used this technique to accurately measure the RPMs of a mechanism (sound cards have a pretty good timebase) and to look for valve sealing problems in an engine.
You can also use a cheap audio recorder to take samples in the field for later analysis on a computer. Just make sure it's recording lossless.
But Uncle, his reviews are real - they say so right in the title!
Good to see you having fun with some good olø Danish quality in those Danfoss transducers.
ave ur a legend love the vids man
awesome vid, I'd love to see you do more with transducers. I work for Cummins as a technician, and our procedure to determine how much compression an engine has isn't a compression test, but measuring blowby with a manometer. I want to build something with a pressure transducer that can measure crankcase pressure, and sync it with an engine position sensor on my oscilloscope to attempt to pinpoint bad cylinders rather than condemning a whole engine, which is what usually happens with the general blowby tests. There's a pressure spec for blow by, but there's also a flow spec. Maybe I could use two transducers across an orifice and calculate flow? I'd love to have a little aluminum project box that displayed pressure and flow but I can't figure out the Arduino code or math. Any help would be greatly appreciated.
great vid, so few practical vids on youtube, thanks.
This video reminded me of all the "new old stock" pressure transmitters and RTDs and other parts I've got squirreled away in case the warehouse is out of stock, even though it never is.....
Pressure transducers, decomissioned PLCs, entire functioning building alarm systems that were meant for the bin. My parts hoard grows and grows. You never know, I might need to install an entirely dedicated alarm system with card access, electric door strikes and a door intercom in my garage.
Hello, thanks for the video. I am trying to calibrate Omega PX-319 pressure transducer with omega's wireless voltage data logger. I am not able to figure out a way to do so. Kindly help me with this.
Strain gauges running on a balanced dc offset inside a complicated bridge similar to a Wheatstone. They usually also have temperature compensating resistors to maintain consistency as well as modulus balancer resistor(s) to keep that dc offset.
These things are really everywhere. More and more gas stations are starting to utilize pressure transducers for line leak detection. Like stated they rarely do go bad and normally the pigtail and connectors go long before the actual transducer goes out. If you get your hands on one you should do a year down on a mechanical leak detector for people.
‼️‼️GREAT video brother
Hmm could the pitch of a smaller bolt maybe get more tension :? since the pitch is smaller usually that results in more torque ? although the thing can twitch but what if you used the same thickness rod with the smallest pitch possible ? as long as it wont strip.
Same deal as a load cell for industrial weighing of carcasses. Turning gravity into different amounts of angry pixies. The most I remember from those days is having to check the load cells for accuracy by manually moving 300 kg of weights on and off the scales 20kg at a time for the most part.
Do they make a transducer that converts flatulence pressure into beautiful music?
While some of it has to do with marketing wank, it's mainly for repetition. It's a lot easier to polish the washers, use fresh grease and standardize the size than it is to repeat the same level of corrosion, the same thread galling, the same schmoo in the threads and all of those real-world variables. It does give a higher number, but mainly it gives a more consistent number to allow more accurate comparisons between different tools. Some marketing "geniuses" (not naming names here but they're Fraught of Horror) try to throw those numbers out there as if they were real-world numbers when it's really just meant to be a way to compare it to another brand.
Your set-up is excellent and you're a genius to use a pressure transducer and an o-smell-oscope to see the actual pressure waves. I deal with these nearly every day for oil and boost pressure logging and it would have taken me a long time to think of using them in the way you just did. I think it would be interesting to see different types of harmonic balancers (and maybe imbalancers, if that's a thing) and see if the oil transducer picks up any spikes.
G'day, sir.
I have actually used sockets almost that big. swapping castings from old boilers too new, because the castings contour the round boiler shell the only way to get them off is is to cut the studs off flush with the boiler. a good way to do this is to use an impact to twist the stud right off. they usually shear off right at the boiler.
is there any way, that you know of to use something like the transducer to INJECT a signal into a closed pressure system. I am trying to use the device to find pinhole leaks in refrigerant circuits
There are a lot of techs taking the cheap eBay transducers for in cylinder compression testing on cars. Some of the issues are slow sample rates and they won’t read below zero when the cylinder has a slight vacuum. Do you have a source for the better quality ones?
Would using a zener diode or a voltage regulator be necessary to provide a constant reference voltage level from your battery supplies? Would that effect the accuracy of the results?
In industry pressure transducers/transmitters usually (at least pre-digital systems) used 4-20 mA. This allowed using only 2 wires to the device which would compensate for lead length.
I've got half a dozen on my shelf that are worth $10k each that can't be used because we did major environmental testing on them.
hay. what do you think about those stanley grinders and that company overall. their tool line.
very interesting, thanks for sharing.
Question!!! I've always been vexed on why a ducer reads higher pre check valve (flapper style) than post!!! We're dealing with 8-9k psi at 2,500 to 3,000 gpm, and pre is always (no matter what) several hundred psi more than post! These ducers are regularly calibrated and replaced as needed!
I get all nostalgic about little Denmark when you describe a part form Danfoss as a LEGO brick part ;)
I maintain sterilizers (autoclaves) , and they use pressure transducers, so i look forward to this video.
Live Zero - I learnt something! Thank you!
Great video to show to the students :) I'll go order some stickers
Did you account for the 14.7psi that is sea level pressure? That might account for the difference in what live zero and what is registered.
Ave, looking at these transducers, is a Chevy knock sensor a type of transducer?
great video will be putting one of those in the truck
We use these transducers all over town to measure pressure at points of our water distribution system. We have to replace them often.
For your blips in the hydraulic noise, is it possible you're seeing a 60 Hz signal from your AC mains power? It's a little hard for me to see your axis, but thought I'd ask.
gotta love a scope I use them to diagnose bad fuel pumps all the time. kinda interested if I can adapt this into making a compression tester for my scope
Thank you for this
good flow in the rant there. a bit of self checking then up a notch for the conclusion. the synaptic harmonics of the system.
Are these used for long term logging? That would be pretty handy
PTFE tape. Just how much do you use on fittings?
yeeeeeees!!! I was thinking you should replace that gage with a transducer!
In converting the voltage readings to pressure, is that relationship (math) always linear? I've seen one or two data sheets which supply a formula for converting the reading to a pressure. Also, does the makeup of the fluid effect the reading for these type of sensors? Can you show us a test rig that could verify the accuracy of the transducer? Thanks in advance.
So 4-20mA is a standard? I dug up an electric adjustable pressure valve that takes a 4-20mA signal and I was scratching my head trying to figure out how to hook it up to an Arduino. Are they generally used with a pressure transducer to self regulate?
Hey AVE
what would be your suggestion for a book for someone, who is studying mechanical engineering and would like to learn more awesome tricks like these?
Does that thing also measure BAC when you blow on it? Or just groan happily when you're done.
Any idea what the transducers in the plumbing section of a local hardware store are for? I has the feller who does plumbing and he told me "Gary knows, but he retired."
7:00 .. an overpressure valve pooping ;)?
popping*
What leads did you end up putting on your el-cheapo meter?
It's like sweeps weeks watching a half dozen previous videos of his meshing to some climax.
Dr Richard Head might be the best thing I've ever heard.
havent commented in a while but im still here. been busy with the company take over and 40% pay raise so im all business lately. need more boltr's
those things are like flame rods/sensors in gas fired equipment. turns a direct flame into a dc signal using flame ionization. then you measure it using microamp reading. most residential and commercial are around 2-4micro amps
For arduino take a look at the ams1115 it's a 16 bit i2c based a2d. good enough for some medium speed data logging, cheaper than dirt, and easier to use than SPI ones.
Ave please do a video on stepless drill bits and step bits.
