ZMJ100PRDH Density Micro-Moisture Integrated Collector

Remote density monitor and dew point sensor are integrated to achieve in situ collection and processing and report the density, pressure, temperature, and micro-water content information simultaneously. These instruments are used to monitor the density, pressure, temperature and micro-water content of SF6 gas in sealed tanks and able to display the gas density on the site display and to provide signal outputs when the density value reaches the set value; they can transmit the real-time remote data of SF6 gas density, pressure, temperature, and micro-water and achieve the online remote monitoring. They are designed to monitor High Voltage systems. They can provide multiple solutions to support new substations and the intelligent transformation of existing substations.
