OUTPUT VOLTAGE TEMPERATURE TRANSDUCER

OUTPUT VOLTAGE TEMPERATURE TRANSDUCER

OUTPUT VOLTAGE TEMPERATURE TRANSDUCER

(OP)
I have some questions on what internal components could affect the Output Voltage of a Temperature Transducer.  In particular causing the output to spike and than go to 0 or just to go directly to 0 or no voltage output.  My background is mechanical, but I have been tasked with solving this one and electronics is not my strong suit.  Any information would be greatly appreciated to help me at least get pointed in the right direction and concentrate my search on the correct components.

Thanks,

Major

RE: OUTPUT VOLTAGE TEMPERATURE TRANSDUCER

The first thing I would look at (and it's the most common problem) is a damaged cable.  You mentioned intermittent operation so the cable may have a damage contact or conductor.

RE: OUTPUT VOLTAGE TEMPERATURE TRANSDUCER

Is the transducer a thermocouple, or an RTD? I agree with C. Hugh, the most likely problem is in the cable or connector. Also make sure you don't have a ground problem. If it is a TC make sure you don't have a bad reference.
