Displacement sensor and wear monitoring on reciprocating compressors

2025-09-02T10:58:25+02:00

Displacement sensor and wear monitoring on reciprocating compressors As shown in previous movies there are different probes to monitor the compressor behavior. In the video we would like to talk about the proximity probe to monitor the vertical piston rod displacement. This probe is installed close to the packing [...]
