Density monitoring device GDM-100

alarmenvironmentalSF6

Medium and high-voltage equipment Gas density monitoring of closed SF6 gas tanks Raising an alarm when defined limit values have been reached Special Features Local indication with switch contacts Temperature-compensated and hermetically sealed, therefore no influence of temperature fluctuations, height differences and atmospheric pressure fluctuations Compensation possible for gas mixtures Functional check or calibration possible without dismounting, in accordance with EU regulation no. 517/2014 on fluorinated greenhouse gases Test connection is welded to prevent leakage 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. Via the on-site indication, the pressure based on 20 °C [68 °F] can be read directly on the instrument. 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 [48.50 lb] SF6 gas and the plant was commissioned after 1 January 2017. With the help of the firmly welded calibration valve, the gas density monitor can be shut off from the process and calibrated without having to disassemble it. This not only reduces maintenance time but also minimises the risks of SF6 gas emissions and potential leakages during recommissioning.
