The MT-15, a self-powered digital hour meter for electric motors, keeps track of true motor running time for all types of AC or DC electric motors. The unit is powered by an internal lithium battery. No external power connections are required. Resettable version also available. The operation of the hour meter is triggered by a sensor attached at the end of a 4 feet (1.3m) external cable. When placed on the motor, the sensor senses the magnetic field through the motor casing. Since the unit is triggered by the motor's magnetic field, the hours display actual operation. This is useful for maintenance and warranty applications for any type of AC or DC powered electric motor. When the motor is ON, the hours icon will blink indicating hour meter is active.
With solid state technology, the unit is built for maximum durability for harsh environments and rugged applications.
