EGE Elektronik Sensor Air Flow Sensors Productseries LG 518 GPL

Description

The EGE Elektronik LG 518 GPL is the authoritative choice for industrial air management where a flange mount is insufficient. The G1/2 thread allows the sensor to be screwed directly into a T-piece or welded sleeve, ensuring a pressure-resistant seal up to 20 bar. This makes it the ideal candidate for monitoring secondary compressed air lines or gas delivery systems where mechanical integrity is paramount. The “GPL” designation signifies a standard 24V DC operating voltage with a PNP transistor output, compatible with virtually all industrial PLC architectures. Unlike the plug-in version, the LG 518 GPL features a factory-sealed fixed cable, which provides a superior hermetic connection and eliminates the risk of accidental disconnection or moisture ingress at the connector point.
