Gas expansion thermometers with alarm contact Typ: G21

Accuracy class 1.0
NG 100 and 160, bayonet housing
Probe stainless steel

application:
These very robust thermometers are suitable for use in chemical process engineering and in the food industry. Electrical or pneumatic limit switches close or open circuits depending on the respective actual value pointer position. The functions of the individual contacts can be executed optionally. The limit switches can be adjusted independently of each other over the entire measuring range. In places with high dynamic loads, fast load changes and pressure peaks or vibrations we recommend the version with a special oil filling (only possible with round housings).
