The PMM-300 "Four-channel" system is perfectly suited for the protection and monitoring of all rotating machines.

It has been mainly developed for the monitoring of hydro generators. The system performs shaft and bearing vibration monitoring according to ISO-7919 and ISO-10816, including advanced monitoring functions such as harmonic and phase calculation. It can also monitor air gap, magnetic flux, endwinding and runner clearance monitoring.

The system is equipped with 4x 4...20mA outputs, 4x relays, 13x digital outputs and 1x modbus RTU interface. It can be configured via TCP/IP using specific configuration software. The configuration software includes a real-time module for data visualisation.

The PMM-300 can be connected to the CMS-500 Orca database for data logging.
