摘要： An electrochemical gas sensor with a stacked arrangement of electrodes and nonwoven layers arranged in parallel, comprising at least one measuring electrode (3) and at least one counterelectrode (5). A porous membrane (8) that is permeable to air is in contact with the stacked arrangement of electrodes and nonwoven layers arranged in parallel at least on one side, at least one layer of a hydrophilic nonwoven (7) is located between the electrodes. The porous membrane (8) that is permeable to air and the hydrophilic nonwoven (7) extend into a separate equalization volume (9), which is filled with electrolyte at least partially and is located at least partially in one plane with the electrodes. The separate equalization volume (9) surrounds the electrode arrangement at least partially in this plane, and the porous membrane (8) that is permeable to air is exposed to ambient pressure at least in partial areas. Such sensors are characterized by a flat shape, high insensitivity to shocks, independence from the position, and high tolerance to variations in environmental humidity.

摘要： The invention is directed to an electrochemical measuring cell 1 for detecting different gas components. The electrochemical measuring cell includes several measuring electrodes (8, 12, 13), a common counter electrode 21 and a common reference electrode 20 in an aqueous electrolyte 3. The measuring electrodes each include a diffusion membrane (7, 11) and individual diaphragms (9, 14) limiting the inflow of gas to the individual measuring electrodes (8, 12). The diffusion membranes (7, 11) cover the measuring electrodes (8, 12, 13). The measuring cell 1 is so improved that the selectivity of the detection of different gas components is improved. An electrolyte barrier 19 is provided at least between one of the measuring electrodes 8 and the remaining measuring electrodes (12, 13). The electrolyte barrier 19 prevents lateral diffusion within the diffusion membrane (7, 11).

摘要： The present invention pertains to an electronic measuring cell for detecting components in fluid media. Such a measuring cell is to be improved such that hermetic sealing of the contact wires leading out of the measuring cell is possible in a housing of a slightly modified design to prevent electrolyte from escaping. To achieve this, an annular space extending in parallel to the circumferential direction of the housing between the measuring cell cover and the housing is filled with an electrolyte- and temperature-resistant sealing material, and the contact wires are led through.

摘要： An explosion-proof gas sensor has a measuring element (2), which generates a measured signal that depends on the concentration of the measured gas and is delimited against the environment by means of a porous, gas-permeable and sintered metal body (7). The sintered metal body (7) has a high mechanical stability, so that the use of additional components, which hinder the diffusion of the gas to be measured into the gas sensor and thus prolong the response time of the gas sensor, can be eliminated.

摘要： A gas sensor is provided that is delimited from the environment with a preferably replaceable cap (8) made of a porous, gas-permeable and water-impermeable material, especially sintered PTFE. The gas sensor is protected against environmental moisture and can be permanently provided with the cap (8) and with a special calibrating adapter (9) both during the gas measurement and during the necessary calibration. Due to the special design of the cap (8) and the calibrating adapter (9), the gas sensor offers the possibility of remote calibration, which can be carried out with high accuracy and is independent from weather effects, especially wind.
