A method for purifying a gas sensor from the cross-flow type and apparatus for the detection of a gas concentration under application of the method

摘要

a sensorreinigungsverfahren and nachweisvorrichtung, a simple and accurate measurement of gas concentration over a prolonged period possible.$a procedure is based on the value of a grenzstroms, for creating a dc voltage on a pair of a positive (3) and negative (2) electrodes of a sensor (1) is produced, and the electrodes (3, 2) of a porous material is formed in close contact with the surface of e ines festelektrolytsubstrats (10) are arranged in the level of oxygen ion conductivity.and in the pores of the negative electrode at the same time as gasdiffusionsbegrenzungsu00f6ffnungen (7) to limit the diffusionsmenge of the gas to be measured is used.if the grenzstromeigenschaften of the sensor (1) to the voltage applied to deteriorate, a voltage of the opposite is used during the measurement, and to return to a normal properties.
