    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 adapter (1) and electrochemical gas sensor (2) is provided with an electrochemical gas sensor housing (14) accommodating an electrolyte (13), with at least one measuring electrode (12) arranged therein and with a membrane (11), which screens the measuring electrode (12) from a measured gas and is permeable to the measured gas. The measuring sensitivity of an electrochemical gas sensor is increased by the adapter (1) having a gas-impermeable surface (15) extending in parallel to and at a spaced location from the membrane (11). The adapter (1) and the membrane (11) form a flow gap (10) for the measured gas delivered by a pump. The adapter (1) may be plugged onto the electrochemical sensor (2) at its outer edge (1a). The measured gas enters through a central opening (17), expands in the flow gap (10) radially to the outside and leaves same via the ring-shaped gap (16).
