Process density sensor GD-20-W

compact

Permanent monitoring of the relevant gas condition parameters in closed tanks For indoor and outdoor SF6-insulated equipment Density measurement of alternative gases in electrical equipment or in the laboratory General pressure and temperature measurement of non-corrosive media, e.g. transformer oil, in power transmission applications Special features High-accuracy sensor technology Wireless LoRaWAN® output signal Long battery life Very good long-term stability and EMC characteristics Very compact design Description Permanent monitoring In order to prevent system failures in switchgear and network outages, the permanent monitoring of the gas density is essential. The model GD-20-W calculates the current gas density from the pressure and temperature using a complex virial equation in the gas density sensor’s powerful microprocessor. Pressure changes resulting from temperature effects will be compensated by this and will not affect the output value. Signal stability Due to its high long-term stability, the sensor is maintenance-free and requires no calibration. Due to the hermetically sealed weld seam and a measuring cell design without sealing elements, the permanent sealing of the measuring cell is ensured. LoRaWAN® output signal This gas density sensor requires no external power supply due to an integrated, easily replaceable battery. By means of the integrated antenna, the sensor reliably transmits the measured values based on the LoRaWAN® protocol even over long distances. Integrated alarm function The independent sensor enables a variety of alarm settings, including alarms at low densities or high temperatures.
