Power Monitor

Finish Thompson’s deluxe M20 Power Monitor with digital display and PLC output provides outstanding protection against pump failure due to run dry, dead heading, excess power, de-coupling and lack of priming (SP Series).

The M20 operates at 50 or 60 Hz, is easy to install, and offers four levels of protection (pre-alarm minimum & maximum power; alarm minimum & maximum power). Just three models cover all motor voltages up to 690 VAC and a transducer is included with each M20 at no additional charge.

For selection assistance, please contact Finish Thompson. Please have the voltage the motor will operate at and, if not ordering a motor with the pump, please also provide the motor data (i.e. brand, single or 3-phase, HP, etc.).
