EGE Elektronik Sensor for Explosive Productseries ST 111 KH-L110

Description

EGE Elektronik Sensor for Explosive Productseries ST 111 KH-L110 is the authoritative choice for critical process monitoring in refineries, chemical plants, and pharmaceutical reactors. While most explosive-rated sensors are limited to Zone 1, the ST 111 series meets the stringent requirements for Zone 0 (Gas) and Zone 20 (Dust). This means it can safely be installed inside tanks and pipes where a combustible atmosphere is a permanent condition. The “L110” designation signifies a 110mm probe length. This extra reach is specifically engineered to bypass thick thermal insulation jackets, protective cladding, or deep mounting nozzles. By reaching deep into the process stream, the ST 111 KH-L110 ensures the sensing tip captures an accurate representation of the core flow velocity.
