High-precision gas insulated substation Density Monitors

The gas density transmitter GDS-M continuously monitors the pressure and temperature of the insulating gas sf 6. For this purpose it possesses a piezoresistive pressure sensor and an evaluation unit with microprocessor. The measured values can be transmitted to a PC or the customer's own diagnostic system.

  • High-precision density sensor for concentration monitoring

    Nov 01, 20132. Monitoring of gas-insulated electrical equipment. For electrical insulation of high and medium voltage equipment, pure SF 6 or mixtures of SF 6 with other gases (e.g., N 2, CF 4) are commonly used . The reliable operation of such devices requires that the gas content is kept in a safe range. Typically, for this purpose the gas density isCited by: 11
