Power meter for engine / motor testbeds
This versatile, high precision power measuring display takes two digital signals (RS485) from our INT4-L Torque and INT4-C RPM meters and computes kW, HP or BHP with extremely high precision.
It can provide serial data out to your data acquisition system and can be combined with our INT4-P Pressure and temperature displays so you can measure, display and record any important physical variable.
Ideal for internal combustion, electric, renewable and stored-energy motors.
