We are experiencing RTD failures on the high temperature discharge measurement on a reciprocating compressor. This is a 4-cylinder compressor (2-stage, I think), and the RTDs on nozzles #3 and #4 fail after a few weeks.
We think it is from vibration, so we bought new AllTemp RTDs that were designed to withstand high vibration. They failed after two weeks.
We're crawling along using the old pneumatic shutdowns.
Anybody else have a similar problem? I'm thinking that thermocouples would last longer, since they're more robust than RTDs. Otherwise, any suggestions are welcome. Thanks.
