ZMJ100PR Remote-Transmission Density Monitor

These good gas density monitors are used to monitor SF6 gas density in sealed tanks. They are applied to indicate gas density and to provide a signal outputs when the when the density reaches the set value. They are able to transmit the real-time data of SF6 gas density remotely 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.

Feature of ZMJ100PR Remote-Transmission Density Monitor

  • The temperature compensator ensures greater accuracy of instrumentation pressure measurement. 

  • Perfect mechanical and electronic combination, local indication and instrumentation control. The precise mechanical structure allows the electronic signal to be transmitted in real time. 

  • RS485 bus interface, system expansion facilitating, remote control and remote control. High capacity for anti-electromagnetic interference. 

  • Suitable for installation indoor or outdoor. 

  • Hermetically sealed case of stainless steel AISI 304 

  • AISI 316 stainless steel gas connecting tubes 

  • The display value and output signals on the screen are independent of the external impact, such as altitude 

  • 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
