QJ4-50C type multifunctional gas relayDetailed product description：

Structural characteristics of QJ4-50C multifunctional gas relay product

1. This product has an oil level display function, and the oil level can be observed through the window.
2. At the same time, it has an installation detection function. After the product is installed and wired, the probe can be used to detect whether the wiring is correct and whether the cut-off signal can be output normally.
3. The gas detection range and the oil level of the alarm signal can be set as needed (for light gas).
4. The range of oil flow velocity detection and the flow rate for cutting off signals can be set as needed (for heavy gas).
5. Equipped with temperature display and alarm function. By outputting temperature signals through temperature sensors, the transformer oil temperature can be displayed on the remote temperature display controller, and an alarm or cut-off signal can be issued to limit the temperature.
