# Gas density switches

> Our gas density switches operate on the reference chamber principle: A chamber filled with SF 6 gas serves as a reference. With environmental influences, the reference chamber behaves the same as the tank and thus does not cause any change in the switching status. The instruments are suitable for medium and high-voltage levels and can be fitted with up to 4 micro switches. They are notable for their compact dimensions and the very high leak tightness of the reference chamber.
