ABSTRACT:
An electrochemical/gas analyzer providing a rugged contact system for removable sensors capable of withstanding inexpert sensor insertion or removal, providing protection for high impedance input electronics against electrostatic discharge (ESD) damage, and providing automatic connection to diagnostic circuitry upon sensor removal has been developed. The contact system includes a plurality of stamped contacts electrically connecting a diagnostic circuit, including a source of diagnostic signals and a ground path, to analyzer signal processing circuitry. Removal of a sensor from this system electrically connects the sensor signal processing electronics to the diagnostic circuit. Insertion of the sensor interrupts electrical connection between the diagnostic circuit and the stamped contact, which connects the sensor terminals to the signal processing circuitry.
