EGE Elektronik Sensor for Explosive Productseries STS 110 S

Description

The EGE Elektronik Sensor for Explosive Productseries STS 110 S is the authoritative choice for facilities that prioritize high operational uptime alongside rigorous safety standards. The “S” designation indicates a plug-in connector interface. Unlike fixed-cable models, the STS 110 S can be disconnected from the signal line in seconds, allowing for fast sensor exchange, cleaning, or calibration without the need to re-run complex wiring through the plant. Operating on the thermodynamic principle, the STS 110 S utilizes a solid-state probe to monitor flow velocity. In Zone 0 (Gas) and Zone 20 (Dust), the absence of moving parts is a critical safety requirement. Mechanical flow switches with paddles or turbines are prone to friction, mechanical fatigue, and static discharge—all of which are potential ignition sources. The STS 110 S eliminates these risks entirely by using heat-dissipation sensing.
