Density monitoring device MDK

pressureSF6

These instruments are used to monitor the density of SF6 gas in sealed tanks, and can be widely used in medium voltage switchgear and RMU. They’re suitable for outdoor harsh external conditions. They can provide multiple solutions to support new substations and the intelligent transformation of existing substations. Application SF6 gas insulated RMU SF6 gas Insulated Switchgear Features Gas compensation ensures higher set point accuracy. Micro switch enables normally open contacts and normally closed contacts freely switch to each other. High shock resistance Normally closed contacts will not set a false alarm due to vibration Technical Data Scale range: 0 to 3 bar Accuracy of set point：±2.0% (–30 °C to +50 °C ) Degree of protection: IP42 Ambient conditions: -30°C to 60°C, relative humidity ≤95%RH Leakage rate: ≤1 × 10-9 Pa·m3/s (Helium leakage inspection) Interface size: G1/4 (customizable) Installation method: axial Electrical connection: Plug-in connection cable size: 0.2mm to 2.5mm2 Insulation properties: Insulation resistance: >100 MW (500 V DC) Withstand voltage: 2kV, 50/60 Hz 1 min Contact type: Mirco switch Impact rating: 15g Contact electrical parameters: 30W/50VA, 1A (maximum) 220VDC/380V 50/60Hz (maximum) Weight: 0.3kg Pressure element: European bourdon tubes Options: Measurement Scale Wide temperature range -60°C to +60°C Can detect SF6, Air, N2, SF6 + N2 and other gases
