Jeti Telemetry Sensor RPM Opto MRPM EX

Jeti Telemetry Sensor RPM Opto MRPM EX. MRPM EX module is designed to measure the RPM of all types of engines. The measurement is performed by using optical sensor. Module MRPM measures actual rotation and actual power of the propeller. The max speed and the max propeller output power are recorded as well. For display of measured values JETIBOX terminal is used, with the possibility of wireless transmission of information in real time using the DUPLEX 2,4 GHz system. The Opto MRPM EX sensor is used to optically measure the speed (RPM) of propeller driven models. The optic sensor calculates RPM by monitoring the interruption of light (sunlight or incandescent light). The optical sensor is housed inside a metal tube to help reduce unwanted reflections for better accuracy. Using the JetiBox, the Opto MRPM EX allows you to set your propeller blade count, multiple alarms and can even display the motor power in Watts.
