  • System of monitoring rotational time of rotatable equipment
    Patent number: 9567850
    Abstract: A system for monitoring rotational time of a rotational equipment. At least some of the illustrative embodiments are systems comprising a rotatable equipment, a sensor, and an electronic system. The sensor is coupled to the rotatable equipment, and is configured to sense rotation of the rotatable equipment. The electronic system is electrically couple to the sensor. The electronic system is self-contained, and is configured to power the sensor to determine rotational time of the rotatable equipment.
