Title: Sensor connection judging circuit for constant potential electrolysis type gas measuring apparatus

IPC: G01N27/27
Filed: 1987-12-14
Abstract: PURPOSE: To enable monitoring of a connection state constantly without affecting a sensor itself by grounding either the operation electrode or the counter electrode of a constant potential electrolytic type sensor via a reactance coil. CONSTITUTION: When a target gas enters a sensor 1 in a state where a constant potential is being applied by a measurement circuit 3, an electrolytic current that is proportional to gas concentration flows between a counter electrode 2 and an operation electrode 4 so that the resistance of the sensor 1 changes in proportion with the gas concentration, thus measuring gas concentration. Pulses outputted from a pulse generator 6 are applied to the operation electrode 4 of the sensor 1 and a reactance coil 5. However, since the counter electrode 2 and the operation electrode 4 are arranged oppositely via an electrolyte in the sensor 1 and a capacitor is formed in terms of AC, pulses pass through the sensor 1 at a low impedance and flow to the ground via the circuit 3.  As a result, the operation electrode 4 is placed in the state of being grounded for the pulses and voltages at a level that can be detected are generated between the terminals of the coil 5.
