Description

The EGE Elektronik Sensor for Explosive Productseries STS 111 KH-L110 is the authoritative choice for precision flow monitoring in deep-walled vessels or heavily insulated small-bore pipes. While most sensors with a 110mm probe length require large mounting threads, the STS 111 series maintains a compact G1/4″ profile, allowing for deep immersion even in space-constrained manifolds or reactor lids. Operating on the thermodynamic principle, the sensor utilizes a solid-state probe to monitor flow velocity. This technology is vital for Zone 0 (Gas) and Zone 20 (Dust) safety as it contains no moving parts. In explosive environments, mechanical flow switches are prone to failure, friction-induced heat, or static discharge—all potential ignition sources. The STS 111 KH-L110 provides a spark-free, maintenance-free alternative.
