QJ2-40C type multifunctional gas relayDetailed product description：

QJ2-40C Multi functional Gas Relay

1. The floating ball is made of imported stainless steel material, which completely solves the problems of oil absorption aging and buoyancy.
2. The gas detection range is large, completely solving the problem of frequent alarms and trips. The oil levels for alarm signals and cut-off signals can be set as needed.
3. It has installation detection function. After the product installation and wiring are completed, the probe can be used to detect whether the wiring is correct and whether the alarm signal and disconnection signal can be output normally.
4. It has a low oil level alarm function.
5. It has an oil level display function, and the oil level above the lid can be observed through the left window, while the oil level below the tank lid can be observed through the right window.
6. It has the function of a pressure relief valve.
7. It has temperature display and alarm function. By outputting temperature signals through temperature sensors, the transformer oil top temperature can be displayed on the remote temperature display controller, and an alarm or cut-off signal can be issued to limit the temperature.
