Measuring device i.e. solid electrolytic gas sensor, for determining partial pressure of components contained in gas mixture, has sensor element arranged in measuring chamber and staying in contact with measuring gas by diffusion element

摘要

The device (2) has a sensor element (3) arranged in a measuring chamber (4) such that the sensor element with a carrier element is arranged on an inner base surface of the device and a non gas filled space is formed below the sensor element. The sensor element is free from forced convection, and stays in contact with measuring gas (6) by a diffusion element (5). The sensor element is fixed at thermal insulating material and is provided with heat radiation reflecting, and partially or completely enclosing surfaces.
