EGE Elektronik Sensor Air Flow Sensors Productseries STS 215 S

Description

The EGE Elektronik STS 215 S is the authoritative choice for industrial applications where the sensor must reach deeper into a pipe or duct to capture an accurate flow profile. The STS 215 S is distinguished by its extended probe length, ensuring the sensing tip is positioned correctly beyond the boundary layer of the pipe wall, even in larger diameter systems. The “S” designation indicates the inclusion of a standardized M12 plug connector. This modular interface is highly valued in modern manufacturing for reducing “Mean Time To Repair” (MTTR), as it allows for rapid sensor replacement or disconnection for calibration without the need to pull new cables through conduits.
