Abstract

A valve monitoring system includes a latching valve, a travel sensor, and a processor. The latching valve has a snap spring, a valve piston, and an inlet port. The travel sensor is for measuring travel of the valve piston between an activation pressure and a zero pressure. The processor is connected to the travel sensor for calculating a rate of travel of the valve piston and determining a latched state of the valve. In some example embodiments, the activation pressure is greater than a normal operating pressure. In some example embodiments, determining a latched state of the valve includes calculating a derivative of the rate of travel.
