An embodiment of a system is described that comprises an ionization chamber electrically coupled with a charge amplifier circuit by a reed switch. The reed switch of the embodiments described herein produces substantially no leakage current and electrically insulates the charge amplifier from the ionization chamber.

System and method for an interrupt mode ion chamber

A signal adapter comprising an explosion proof housing, a circuit member disposed on an inside of the explosion proof housing, a signal input connector electrically connected to the circuit member, a signal output connector electrically connected to the circuit member, and a seal disposed on the inside of the explosion proof housing and around the circuit member, creating an explosion proof seal between the signal input connector and the signal output connector.

Signal adapter

A proximity sensor module includes a housing; and a proximity sensor disposed in the housing, wherein the proximity sensor comprises a sensor plate configured to contact inside of the housing such that substantially no gap exists between the sensor plate and the housing. The housing may be a substantially explosion-proof housing. The housing may include two members coupled by a thread engagement, wherein a sensor plate of the proximity sensor is placed off-center with respect to an axis of rotation for the thread engagement.
