  • High-Precision Density Sensor for Concentration Monitoring

    The gas density sensor is self-calibrating and specifically designed to operate as a sulfur hexafluoride (SF6) monitor and control device in gas insulated high-voltage switchgears (GIS), but can

  • High-precision density sensor for concentration monitoring

    2013-11-1A pre-requisite for highly precise concentration readings with a (pTρ)-sensor system is a high absolute density measurement accuracy which we realized by an empirical temperature compensation.The density sensor consists of two identical microcrystal tuning forks of resonance frequency f = 2 15 Hz = 32,768 Hz, which are electrically excited to resonant oscillations.

  • US6125692A - Density sensor for monitoring the rate of

    A density sensor for monitoring a rate of leakage from the case of electrical switchgear filled with dielectric gas under pressure, the sensor comprising a fixing support mounted from the outside in the thickness of the case and communicating with the dielectric gas. A radiator is placed around the fixing support of the density sensor, thereby enabling a measurement artifact that is due to the

  • Gas density monitors and gas density sensors for SF6 and

    Trafag gas monitoring devices measure the gas density directly, i.e. SF 6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF 6 Gas Density Sensors, or by combining both principles, i.e.SF 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF 6 gas density.

  • On-line PD Monitoring of Gas Insulated Switchgear (GIS) - HVPD

    PD monitoring is an essential part of any electrical condition monitoring programme, as it is the best early warning indicator of incipient faults in GIS due to insulation degradation. Unplanned outages due to GIS switchgear failures can cost millions of pounds in equipment replacement cost and loss of income, for example, the failure of only
