Optimized for the unique challenges of protecting and monitoring reciprocating machines

Avoid unexpected failures of reciprocating compressors with Reciprocating Machine Protectors. Proven methods of monitoring the condition of rotating equipment do not work well on reciprocating machines. This RMP product detects impacts caused by the loosening of internal parts. Depending on the impact amplitude and the number of times the impact occurs within a specified time window, the appropriate 4-20 mA signal is provided. Industry-leading USB programming capability makes it easy to adapt the RMP to any alternative application. To keep machines running smoothly, the RMP is used to trend peak acceleration data.
