Troubleshooting A 4-20mA Submersible Level Transducer In the Field With A Fluke 789 Process Meter

Step by step in the field troubleshooting of a submersible level transducer with a Fluke 789 process meter. Understanding and troubleshooting 4-20mA signals is one aspect of being a Control Systems Technician.

Great video! Super informative nice to see real life issues!

[@ender198]

Awesome! Very enjoyable.

Excellent ! Thanks for the training

[@williemasonjohnson]

Awesome, thank you for sharing very informative!

Very interesting seeing troubleshooting in real time.

The wiring is busch league, install some Panduit and clean it up so it looks professional.

Welcome to the industrial world

My millwright brain can barely process this but very interesting!

Will the 789 meter generate 12 volts on a 12 volt system, such as a vehicle or only good for the 24 volt systems?

It's built in power supply is only for sourcing 24vdc loop power for 0-24ma current circuits. It can also sink using an external power supply.

Hay, Can I ask you something? How does the radio guy know the PLC raw value is from 6500 to 32k for that level sensor range? If we don't know, could we just give the 4-20mA from 789 and find out the min & max raw data range for that level sensor? Or Have to find that PLC manual for analog card raw data? Or is there another way?

[@Up-CountryElectric]

That's the standard range for an analog input converted to a signed 16-bit integer. Some PLCs and equipment use different values, but the PLCs we use all utilize a signed 16-bit integer with a range of 0-32k.

Where can I get those very useful equations like the one you used 15 ÷ 2.31 ) like is there any books or anything like that?

[@Up-CountryElectric]

That equation is "feet of head (elevation) to PSI"
Google.com and TH-cam videos 😜
