FUNCTIONAL TESTING OF THERMAL CONDUCTIVITY GAS SENSORS

摘要

#CMT# #/CMT# The method involves determining the signal current value of a gas sensor based on the determination of measuring voltage of the gas sensor. A first control value is determined by comparing the signal current value with preset current value, if measuring voltage lies within preset voltage value. A second control value is determined by comparing the signal current value with first control current value. An error message regarding the malfunction of sensor is displayed based on the comparison result of control values with a preset control value. #CMT# : #/CMT# An independent claim is included for a gas sensor. #CMT#USE : #/CMT# Method for functional testing of thermal conductivity gas sensor (claimed) used in laboratory and industrial application. #CMT#ADVANTAGE : #/CMT# The functional testing of the thermal conductivity gas sensor can be performed easily and efficiently. The malfunction of the sensor can be determined accurately. The operational efficiency and reliability of the gas sensor can be improved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the thermal conductivity gas sensor. 1 : Sensor main portion 3 : Connection terminal 4 : Flange 5 : Socket 6 : Measuring chamber.
