Application Medium and high-voltage switchgear Special features Functional check or recalibration possible without dismounting,in accordance with EU regulation No. 517/2014 on fluorinated greenhouse gases. People can operate independently without disassembling the screws,which saves effort and time. It can facilitate on-site personnel to measure micro-water and supplement air for switch. Avoid surface scoring and joint damage from disassembly Test connection from stainless steel pipe/or copper pipe for testing other parameters

Applications Medium-voltage equipment Gas density monitoring of closed SF6/or mixed gas tanks Raising an alarm when defined limit values have been reached Special Features Hermetically sealed case from stainless steel On-site display with switch contact Temperature-compensated and hermetically sealed, therefore no influence of temperature fluctuations, differences in level and atmospheric pressure fluctuation Compensation possible for gas mixtures Traceability by serial number Pressure interface customised in accordance with customer requirements. Utmost three pairs of switching contacts can be provided according to the needs of the user

Application Permanent monitoring of the relevant gas condition parameters in closed tanks. For internal and external SF6/ or mixed insulated equipment Special features High-accuracy sensor technology Modbus® output protocol via RS-485 interface, real-time data collection Case from stainless steel,ingress protection IP65 Very good long-term stability and EMC characteristics Compact dimensions Interface size can be customized

Application Medium and high-voltage equipment Handing at SF6/or mixed gas tanks For indoor and outdoor equipment Connecting to SF6/or mixed gas charging and vacuum device Connecting to SF6/or mixed gas recovery device Special features The valves can be disconnected or coupled under pressure or vacuum Vacuum and pressure-tight (-1∼+64 bar) Working temperature -40∼+80℃ Leak rate: ≤ 1·10-8 mbar · l / s Tested helium tightness of 100 % Self sealing: If the device or connector is removed, it can be self sealing Reusable Interface size can be customized

Applications Medium and high-voltage equipment Gas density monitoring of closed SF6/or mixed gas tanks Raising an alarm when defined limit values have been reached Special Features On-site display with switch contact Temperature-compensated and hermetically sealed, therefore no influence of temperature fluctuations,differences in level and atmospheric pressure fluctuations Compensation possible for gas mixtures Functional check or recalibration possible without dismounting, in accordance with EU regulation No. 517/2014 on fluorinated greenhouse gases Hermetically sealed case from AISI 304 stainless steel, test connection is welded to prevent leakage To achieve a maximum of four switch contacts,an overpressure alarm, dual alarm or double locking and many other options make gas density monitor safer and more reliable

Applications Medium and high-voltage equipment Density monitoring of closed SF6/or mixed gas compartment Remote monitoring of the SF6/or mixed gas real-time condition Raising an alarm when defined limit values have been reached Special Features Ideally suited for smart grid or modernisation projects Modbus® delivers measured values for pressure, temperature and gas density as digital signal The 4∼20 mA version outputs the absolute pressure at 20℃[68 °F] or the gas density(g/l) as an analogue signal for SF6 gas Compact design with only one process connection,achieving remote control.High resistance to electromagnetic interference Suitable for alternative gases
