General Technical Description
The gas detector functions using semiconductor gas sensors that respond to even small traces of gases with a reducing effect.
This instrument has proven itself thousands of times over not only through its robustness and long service life but also under unfavourable working conditions.
The instrument is built into an aluminium die-cast casing and has an adjustment potentiometer on the side along with an LED to indicate its switching state.
If the value set is exceeded, then a relay built-in switches over, and the LED lights up or goes dark, depending on the operating mode.
When the gas concentration set is again fallen short of, then the relay switches back to the normal position.
The relay can be connected in two operating modes:
A The relay pulls in when the set point value is exceeded.
B The relay is pulled in and releases when the set point value is exceeded.
