FXM100H Series Mixed Gas Density Monitor

Information:

The FXM1000H Series Mixed Gas Density Monitor is a precision instrument specifically designed for monitoring the density(P20) value of mixed gases which comprising SF6 and various other gases (including) nitrogen, carbon tetrafluoride, oxygen, and carbon dioxide) in sealed containers. 

It is primarily used in gas-insulated equipment utilizing SF6 and mixed gases, such as GIS switchgear, circuit breaker, pole-mounted switches, and transformers.

Via the on-site display, 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 SF6 gas. According to the Chinese JB/T0549-2006 standard, the calibration cycle after the product is put into use generally does not exceed one year.

With the help of the firmly welded calibration valve, the gas density monitor can be shut off from the process and recalibrated 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.
