ABSTRACT:
A non-invasive apparatus and method is disclosed which is adapted for testing of solenoid valves to verify valve operation. The non-invasive apparatus and method monitors with time both the stroke of the solenoid valve plunger to identify associated impacts and the state of the solenoid valve as being energized or de-energized to determine valve operability.
