    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.

    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.

      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..

    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
      @InstrumentationControl  2 года назад

      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!

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

    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

    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.
