EGE Elektronik Sensor for Explosive Productseries ST 101 S

Description

EGE Elektronik Sensor for Explosive Productseries ST 101 S is the authoritative choice for modular industrial systems operating in potentially explosive areas. The “S” designation indicates a plug-in connector design, allowing for rapid sensor replacement or maintenance without the need to re-route fixed cabling—a significant advantage in complex chemical or pharmaceutical skids. Operating on the thermodynamic principle, the ST 101 S uses a solid-state probe to monitor flow velocity. This technology is vital for hazardous zones as it contains no moving parts. Mechanical switches with paddles or turbines can create friction, jamming, or static electricity—all of which are high-risk ignition sources. The ST 101 S provides a spark-free, maintenance-free alternative.
