3.3.2 Technical Implementation
A block made of stainless steel contains two
gas paths. Both, the volume of the block and
the mass of the sensors have been minimi
-
zed in order to obtain short response times.
To suppress influences by changing ambient
temperature the block is thermostatted and
isolated against ambience.
The sensors are fully glass packaged to with-
stand aggressive gases.
