Abstract:
1. A system for monitoring an operating condition of an electrostatic precipitator comprising a rapper configured to mechanically actuate to disengage pollutants from a plate of the electrostatic precipitator, the system comprising: a solenoid coil and a slug disposed within the solenoid coil, the solenoid coil configured to move the slug within the rapper when the solenoid coil is energized; a piezoelectric sensor disposed on the slug for movement therewith, said sensor configured to obtain and transmit signals representative of the movement of the slug within the rapper; an intermediate device electrically coupled to the sensor and configured to wirelessly transmit the signals received from the sensor; and a base station including a receiver configured to receive the signals from the intermediate device and a processor configured to determine whether the rapper is mechanically actuated.
