EGE Elektronik Sensor Air Flow Sensors Productseries LG 518 GPLS

Description

The EGE Elektronik LG 518 GPLS is the authoritative choice for industrial applications that require a pressure-resistant, secure mechanical connection. The “G1/2” threaded design allows the sensor to be screwed directly into a T-piece or a welded sleeve, making it ideal for compressed air lines, nitrogen systems, or high-velocity ventilation pipes where a simple flange mount is insufficient. The “GPLS” designation signifies a 24V DC operating voltage with a PNP transistor output and a standardized M12 connector. This modular electrical interface simplifies installation and allows for rapid sensor replacement during maintenance cycles without the need to rewire the control cabinet.
