規格介紹:WIKA GDM-100
Gas density monitor
詳細介紹:
氣體密度計
With the help of the firmly welded calibration valve, the gas density monitor can be shut off from the process and calibrated without having to disassemble it. This not only reduces maintenance time but also minimises the risks of SF6 gas emissions and potential leakages during recommissioning.
Features:
- • Local indication with switch contacts
- • Temperature-compensated and hermetically sealed
- • Compensation possible for gas mixtures
- • Functional check or calibration possible without dismounting
- • Test connection is welded to prevent leakage

WIKA GDM-RC-100-T Hybrid gas density monitor with reference chamber
混合式氣體密度計 Via the on-site indication, the pressure based on 20 °C [68 °F] can be read directly on the instrument. The model GDM-RC- 100-T can also be configured for alternative insulating gases consisting of N2, CF4, O2, CO2, C4-FN, He and Ar. Features: • Ideally suited for smart grid or modernisation projects • Modbus® delivers measured values for pressure, temperature and gas density as a digital signal • The 4 ... 20 mA version outputs the absolute pressure at 20 °C [68 °F] or the gas density in g/l as an analogue signal • Suitable for SF<sub>6</sub> and alternative insulating gases • Complete on-site indication of the density and vacuum range on a 100 mm [3.94 in] dial
WIKA GDM-RC-100 Gas density monitor with reference chamber
氣體密度計 The model GDM-RC-100 works according to the reference gas principle. The reference gas enables accurate isochore switching and display over the entire temperature range. Temperature changes and atmospheric pressure variations do not affect the measurement. Features: • Accurate isochore, temperature-compensated switching and display over the entire temperature range • Complete local display of the density and vacuum range on a 100-mm dial • Increased plant safety through self-diagnostics • Prepared for any alternative gases • Very high long-term stability through welded reference gas volume
WIKA GDM-100-T Hybrid gas density monitor
混合式氣體密度計 The model GDM-100-T can also be configured for alternative gases consisting of N2, CF4, O2, CO2, 3M™, Nove™ 4710, He and Ar. 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 °C [68 °F] or the gas density in g/l as an analogue signal for SF6 gas • Compact design with only one process connection • Suitable for alternative gases
WIKA GDM-063 Gas density monitor
氣體密度計 The WIKA gas density monitor is hermetically sealed and temperature-compensated. Measured value fluctuations and false alarms caused by changes in either ambient temperature or atmospheric pressure are therefore prevented. Features: • Case and wetted parts from stainless steel • On-site display with switch contact • Temperature-compensated and hermetically sealed • Compensation possible for gas mixtures • Traceability by serial number
WIKA GLTC-CV Recalibration valve for retrofitting
This connection part is used for retrofitting in order to be able to calibrate an existing gas density monitor. The model GLTC-CV is fitted between the gas tank and the gas density monitor. With the help of the calibration valve, the gas density monitor can be shut off from the process and recalibrated without having to disassemble it. Features: • Retrofitting for leakage detection systems • Functional check or recalibration possible without dismounting • Test connection from stainless steel
