Compressor probe temperature compensation
Thread Content
Previously, six or seven centrifugal compressors were installed, including imported models from Siemens and Atlas, as well as domestic models from Shenyang Gear. No consideration was given to temperature compensation at that time. Recently, Hitachi’s units require that temperature be taken into account, with temperature compensation calculations needed. Could you roughly explain how such calculations are done, based on those previously performed?
I’ve never heard of such a requirement before; since they’re making a request, of course they should provide the formula
Compensate for what? Are they using thermocouples? Thermistors don’t require compensation.
The temperature probes of Kobe Steel’s compressor motors all use thermistors for compensation!
Don’t thermal resistors have safety gate compensation? How to provide compensation on-site
Where can one see that there is a thermistor here? Please mark it, so I can learn from it too. Thank you. Also, is the thermistor accurate? It seems that the temperature used by the compressor isn’t that high; this PT100 type is probably the most reliable option, and compensation should also be done using a PT100.

When installing the displacement probe, thermal expansion and contraction were taken into account; it is not used for measuring temperature.
