Monitoring system and method for energized solenoid valves mounted in close proximity to one another

Abstract

A system includes a baghouse filter system comprising a plurality of fabric filters; and a valve system comprising a plurality of solenoid pilot valves each of the plurality of solenoid pilot valves including a solenoid coil, the plurality of solenoid pilot valves being operable to selectively release compressed air into the plurality of fabric filters, respectively, responsive to one or more valve control signals, the valve system further comprising a plurality of sensors associated respectively corresponding to the plurality of solenoid coils, each of the plurality of sensors being configured to output an ambient voltage when its corresponding solenoid coil is not energized, a first voltage when its corresponding solenoid coil is energized, and a second voltage when a neighboring solenoid coil is energized.
