Abstract
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.
Claims20
An electrochemical measuring cell for detecting components in fluid media, comprising:
- a housing accommodating a counterelectrode, a measuring electrode and an electrolyte, said counterelectrode and measuring electrode being in liquid connection with said electrolyte;
- a gas-permeable, electrolyte impermeable diaphragm disposed on one side of said housing, said diaphragm for allowing diffusion contact with said measuring electrode from one side of said housing;
- a measuring cell cover disposed on another side of said housing, said housing being closed by said measuring cell cover, said housing having a recess formed on an inner side of said housing extending in parallel to a circumferential direction of said housing, said recess and an inside surface of said cover cooperating to define a space between said measuring cell cover and said housing;
- and
- electrolyte-temperature-resistant sealing material means filling said space.
