Description

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.

With regard to switchgear safety, asset protection and environmental protection, it is common to perform functional checks on a regular basis. Article 5 of EU regulation no. 517/2014 on fluorinated greenhouse gases, provides for checking of the leakage detection system at least every 6 years if it contains > 22 kg SF6 gas and the plant was commissioned after 01 January 2017.
