EGE Elektronik Sensor for Explosive Productseries ST 101 K

Description

EGE Elektronik Sensor for Explosive Productseries ST 101 K is the authoritative choice for engineering teams managing volatile fluids in restricted spaces. In chemical, pharmaceutical, and oil-and-gas environments, traditional mechanical flow switches can create ignition risks through friction or static buildup. The ST 101 K series eliminates these hazards by using an intrinsically safe (Ex i) design. Operating on the thermodynamic principle, the ST 101 K utilizes a solid-state probe to monitor flow velocity. It contains no moving parts, ensuring a maintenance-free life cycle and high resistance to vibration. The G1/4″ thread allows for seamless integration into compact manifolds and small-diameter lines without requiring heavy-duty plumbing adapters.
