EGE Elektronik Sensor Air Flow Sensors Productseries STS 212 S

Description

The EGE Elektronik STS 212 S is the authoritative choice for facilities requiring an industrial-grade sensor that is easy to maintain and replace. The “S” designation indicates the presence of a standardized M12 connector, allowing for rapid “plug-and-play” installation. This modularity is a major advantage over fixed-cable models, as it significantly reduces downtime during sensor replacement or maintenance cycles. The G1/2 threaded process connection ensures the sensor can be installed directly into a T-piece or welded sleeve with a pressure-resistant, leak-proof seal (capable of withstanding up to 20 bar). This makes the STS 212 S ideal for secondary compressed air lines or process gas systems where mechanical security is paramount.
