This example shows how to make rotating speed measurement and rotation direction determination of a finished fuel pump simultaneously, which is widely used such as in a vehicle. Since the rotating shaft is not come out, it is difficult to make direct measurement by attaching a sensor to the rotating shaft.
The rotating speed and direction of the motor built in a fuel pump can be measured by the FT-2500 advanced tachometer with the FT-0501 magnetic flux leakage sensor. The FT-0501 attached to the fuel pump detects the magnetic flux leakage, and the FT-2500 performs frequency calculation of the magnetic flux changing periodically.

Upper- / lower-limit comparator output function is provided as standard to make OK, LOWER, or UPPER decision in production line use.

Enables data transfer by RS-232C.
