Embodiment Construction

[0047] figure 1 An electrochemical gas sensor 100 for the detection of hydrogen sulphide is shown schematically with a test gas generator 18 for hydrogen sulphide. The gas sensor 100 comprises a sensor housing 1, two, preferably three, noble metal electrodes 2, 5, 6 (in the form of a measuring electrode 6, an auxiliary electrode 2 and a reference electrode 5), an electrolyte 14 and for electrodes 2, 5, The associated contact wires 15 , 16 , 17 (preferably platinum wires) of 6 are inserted into the sensor housing 1 . On the end side, the sensor housing 1 is closed by a gas-permeable membrane 7 (preferably made of a fluorinated porous polymer) impermeable to the electrolyte 14, which seals off the sensor interior from the surrounding atmosphere. open. Measuring electrode 6 is located directly behind gas-permeable membrane 7 in the sensor interior. The electrodes 2 , 5 , 6 are connected to an electronic controller 12 for evaluating the signal of the measuring electrode 6 .

Abstract

The present invention relates to a gas sensor with a test gas generator, concretely, a gas sensor (100) arranged in a sensor housing (1) (the sensor housing (1) has a gas-permeable membrane (7) for the inlet of a gas sample to be analyzed to a measuring electrode (6)) is improved as follows: functional test also includes a gas path to the measuring electrode (6). Thus, provided is the gas sensor (100) with a test gas generator (18) which has a generator housing (6). The generator housing (8) is fastened in the area of the gas-permeable membrane (7), and the gas generator (18) has a central gas outlet opening (21) for the gas sample to pass into the sensor and outlet openings (19) directed towards the gas-permeable membrane (7) for the test gas.

Description

technical field [0001] The invention relates to a gas sensor (Gassensor) with a detection gas generator (Prüfgasgenerator). technical background [0002] Gas warning devices with gas sensors must undergo a function test at regular intervals. Thus, gas sensors can fail, for example due to a blockage of the gas inlet or an ineffective sensor element. The prescribed function of the gas sensor is preferably tested by applying a target gas, wherein the entire functional chain from the gas supply to the signal generation is tested. [0003] Gas sensors commonly used in commerce have a sensitivity drift with respect to the gas components to be detected. This performance of gas sensors cannot be described or predicted by mathematical formulas. It is therefore necessary to calibrate the gas sensor with a known concentration of the target gas at certain time intervals. The length of the calibration interval is determined by the requirements for the accuracy of the gas sensor being...
