What types of primary elements are used to measure the compressor bearing temperature? Give example with the equipment name

At lower range of temperature ‘RTD’ (resistance temperature detector)is preferred to thermo-couples.

On dresser gas compressors: PT 100-RTD is used for measuring the journal and thrust bearing temperature.

On solar gas compressors: ‘k’ type thermo-couple is used for measuring the journal and thrust bearing temperature.
