摘要
An air operated pump (10) uses a magnet (14) mounted in the valve cup (16) of the air motor (18) and two reed sensors (20) mounted in the valve cover (22) to monitor the speed and position of the valve (16). A solenoid (24) is mounted on the valve cover (22) and can be commanded to extend a plunger (26) into the valve cup (16) to stop valve movement and therefore the pump from running away. Three methods may be used to increase battery life and monitor the solenoid plunger position, two of which use the changing inductance of the solenoid (24) to monitor the solenoid movement.
