The DTM20-A4 is designed for monitoring reciprocating compressors & engines. It is a multiple parameter monitor with both impact monitoring and acceleration monitoring. Alarm can be the combination of these two parameters. You can conveniently decide the alarm level of each of the monitored parameters and setup accordingly. In addition to analog transmission, the monitor also supplies a digital output, dual alarms, and a condition monitoring. Thus greatly enhanced the analysis and monitoring capabilities of the system. The looseness monitor conforms to ISO10816-6.
