Common Instrumentation Faults - 4-20 mA Loops

[@jsbaltimore3405]

This channel is awesome. Great explanations. I’ve been doing E&I work for over 10 years and I still learn new things everyday. I look up videos to review and refresh things I haven’t done in a while and found this channel while looking up an EH FMR52. I wish I had this channel years ago when I was brand new to the industry.

Awesome channel! How I know you have experience is from your very first fault…that improper diagnosis from operations cause them to blame the instrument when in fact the instrument is working perfectly fine! And the comment on how working with your operations group to help eliminate some of those issues of always blaming the instrument is always a good way to keep up productivity.

Extraordinary explanation ❤❤

Nice video, well covered in 7 mins! Glad to see you uploading again. Keep them coming :)!

Thanks Lee. It has taken me a while to get back into it with one thing and another. Hoping to keep the videos more regular. Hope you are well mate?

Thanks, will do!

I worked in a complex nickel/cobalt plant and using a milliamp clamp meter was more convenient. You can narrow it down fairly quick without disconnecting. For Level transmitters of radar or ultrasonic type, a power cycle or removal and cleaning usually remedied. For differential transmitters, check the lines are clear through bleeds, if not flush. Check operation by hand pumping to 50,100% in relation to the range in kPa etc.. if this is good likely a process issue. Using a laptop can be advantageous if possible in sub station rather than a communicator depending on the system you have. Always remember to have loops put into calibration before working as process interruptions can happen from you unexpectedly making the instrument read something.

[@InstrumentationControl]

You make some great points here Gary. Having the control room operators put loops into manual is definitely a big one. Thanks for sharing your experience.

I've worked in the Telephone industry and a bit of access controls even. My hobby is electronics and circuits. I've always been interested in control systems and instrumentation. I wish I could go back a few decades and take a different fork in the road..

Which voltage regulator are reliable ?

Very fine knowledge. Thanks alot.

@@InstrumentationControl yes I did. Please I need your support, I'll going for instrumentation interview tomorrow. Any possible guide?

Hello. What will happen on digital display if the termination of wire interchanged on transmitter

[@jsbaltimore3405]

The other day I had something happen for the first time. I was getting 60 mA in my 0-20 mA loop. I would assumed too high of resistance somewhere but it’s a first

[@williamcollett4726]

I used to come across lots of faults on dip pipe level measurement systems, could you do a video on these please? Also just wondering if you ever experienced faults on effluent PH monitoring ?

[@InstrumentationControl]

Dip pipe level measurements are a simple technology but can work great. Often the issues with these are installation related. I may do a video on them one day. In regards to PH monitoring , calibration errors can cause issues. As well as isolation of process mediums. Thanks for your comment William, nice fish!

Hello... I am a new instrument technician. Are there any technical tips that you can help me with? Thank you

[@InstrumentationControl]

Hi there, it's a great career to be involved in. It depends on industry etc. My best tip would be to never stop learning.

[@عبدالرحمنالشجراوي]

Make a video on analyser, ph sensor and gas chromatography. It's complete working.

[@ejchicas7289]

Was wondering where you where at?

[@EricPham-gr8pg]

Resistance change with heat that is why light control is much better but will public trust engineering in military that is the reason for using resistor in circuit

[@johnjones5354]

Operators never trust the instrument reading. That's why they are operators..

[@michealplater9007]

Spending a lot of time, it's not an electrical issue. It does not work that way, in correct selection, it's turned off, it's has been in fault for weeks, the PLC code has changed overnight, etc. etc.
