why 4 to 20 ma signal is used|| process instrumentation || industrial automation || plc

In this video, we will discuss why 4 to 20 ma signal is used in process instrumentation instead of 0 to 20 ma signal. Engineering study is a youtube channel to learn instrumentation engineering. this video is helpful for instrumentation interview questions and answers. the video is delivered in Hindi language. this video is helpful for instrument technicians and instrumentation and control engineers. video is helpful for field instrumentation and instrumentation training videos.

Sir plz one question explain in Hindi
Control valve me class 4 and class 5 kiyaa hotaa h iska mtlb kiyaa plz immediately Just now video upload kre

[@jkbox299]

Par 2to20mA bhi to use kar sakte hai, sir iska bhi answer bataiye

[@masaleemic]

Nahi min3mA needed for transfer

Sir thermocouple ke milivolt ko voltage m kese convert karte h kon se formula se karte h

[@EngineeringStudy]

Aap hamare channel par rtd and thermocouple check video dekh lijiye

[@kuldeeplowvanshi1916]

What Tc , Ti & Td in control valve .& How to set these values

[@EngineeringStudy]

Ok

Mannual me level transmiter ko adjust zero trim kaise karenge sir not used hart

[@ravitechnicali.e7379]

Transmitter me zero & span krne ke liye screw hota he ush se kr de. So not use HART Communicator.

[@mdgulzar4192]

@@ravitechnicali.e7379 screw hota but usko open karne ke baad threee button hota ek button zero trim ke liyeee or dusra span karne ke liye usko adjust kaise karenge sir
For example tank me level hai 90% but transmitter me show kar raha hai 10% ye solution kaise hoga mannual calibration no use hart sir

[@SyedHamedinstrumentation]

6 to 24 kyun nahi lete sir answer bataye

[@instrumentstudy6836]

Because plc dcs card is 1to 5 v working in 4to 20ma according so not use 2 to20ma jk

4 to 20 ma ka jagah 10 to 50 ma bhi to rkha ja skata tha 4 to 20 ma kyun rakha gya ye batao

[@vickygec87]

@@wakilraza1366 Using a standard multimeter we can detect failures or check the 4-20 mA loop easily. Besides there is no personal risk if we touch the wire because voltage is 24VDC and the dangerous current threshold for the heart is 30 mA.

[@wakilraza1366]

@@vickygec87 yes bro i know just given the question 10 to 50 ma because 30ma up current to may be heart shock and another reason 4 t0 20 ma any transmitter electron start to need 3.5 ma so 4 ma given the stander value so 4 to 20 ma start
