Sensors for Monitoring Reciprocating Machinery

Optimized for the unique challenges of protecting
and monitoring reciprocating machinery

Years of frustrating unanticipated reciprocating compressor failures have lead to the development of the new line of IMI® Reciprocating Machinery Protectors. We have learned that the proven successful methods of condition monitoring on rotating equipment do not yield good results on reciprocating devices. IMI® has developed the RMP product line to detect impacts caused by looseness of internal parts. Depending on the amplitude of the impact and how many times the impact occurs within a specified time window, the appropriate 4-20 mA signal is provided. The industry leading USB Programming capability makes it easy to match the RMP to any reciprocating application. For properly running machinery, the IMI® RMP allows you to trend peak acceleration data.
