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.
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?
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.
