EGE Elektronik Sensor Air Flow Sensors Productseries LG 518 GSP

Description

The EGE Elektronik LG 518 GSP is the authoritative choice for industrial air management where a high-integrity mechanical connection is required. The G1/2 thread allows the sensor to be screwed directly into a pipe T-piece, a welded sleeve, or a specialized duct boss. This threaded mounting ensures a leak-proof seal capable of withstanding internal pressures up to 20 bar, making it far more secure than traditional flange-mounted sensors in pressurized environments. The “GSP” designation signifies a standard 24V DC operating voltage with a PNP transistor output, designed for seamless integration into modern industrial control architectures. The fixed cable design provides a superior hermetic seal compared to plug-in versions, eliminating the risk of accidental disconnection or contact corrosion in high-humidity or high-vibration environments.
