Density monitoring device ZMJ60XD

humidityfor tankSF6

These instruments are used to monitor SF6 gas density in sealed tanks. They are applied to indicate the gas density and to provide a signal outputs when the density reaches the set value. They are designed to monitor High Voltage systems. They can provide multiple solutions to support new substations and the intelligent transformation of existing substations. • SF6 Gas Insulated Switchgear (GIS) • SF6 Insulated Circuit Breakers • SF6 Insulated Pole-Mounted Switch • SF6 Insulated Transformers • SF6 Insulated Mutual Inductor • SF6 Insulated Busbar Systems 1. Gas compensation ensures higher set point accuracy 2. Suitable for different indoor and outdoor installation needs 3. Micro switch enables normally open contacts and normally closed contacts freely switch to each other. 4. Up to Four switch contacts can achieve overpressure alarm, dual alarm or double locking and many other solutions, ensuring the monitoring more secure and reliable 5. High shock resistance 6 Without oil, no leakage risks 7. Normally closed contacts will not trigger false alarms due to vibration 1. Scale range: -0.1 to 0.9MPa 2. Accuracy of set point: ±10 kPa （ –30 to +50 °C） 3. Accuracy of indicator: ±10 kPa at 20 °C (within scale range) 4. Degree of protection: IP65 5. Ambient conditions: -40°C to +60°C, relative humidity ≤ 95%RH Leakage rate: ≤1×10-9 Pa·m3/s（Helium leakage inspection） 6. Interface size:M20 × 1.5 (customizable) 7. Installation method: radial or axial
