The MRPM-AC EX sensor is used to measure the speed (RPM) of brushless motors through direct connection with two of the three motor wires. For accurate data, you must set your motor`s pole count in the MRPM-AC EX using the JetiBox. The MRPM-AC EX allows you to set multiple alarms and can even display the motor power in Watts.

Through the Duplex 2.4GHz system and either a JetiBox Profi or Jeti Transmitter you can monitor your motor`s RPM data and alarm conditions in real time.
