Description

Gas density is a crucial operating parameter for medium-voltage switchgear. If the required gas density is not present, safe operation of the plant cannot be guaranteed.

The WIKA gas density measuring instruments provide reliable warnings against dangerously low gas levels, even under extreme ambient conditions. Electrical switch contacts warn the plant operator when the gas density drops below defined levels due to leakage.
