EGE Elektronik Sensor for Explosive Productseries ST 110 K-L140

Description

EGE Elektronik Sensor for Explosive Productseries ST 110 K-L140 is the authoritative choice for monitoring flow in volatile industrial environments where standard probes cannot reach the core flow profile. The “L140” designation refers to the 140mm probe length, which allows the sensing tip to bypass thick thermal insulation jackets, protective cladding, or exceptionally deep mounting sockets to reach the center of the medium stream. Operating on the thermodynamic principle, the sensor utilizes a solid-state probe to monitor flow velocity. This technology is inherently safer for hazardous zones because it contains no moving parts, eliminating the risks of mechanical friction, static discharge, or paddle fatigue—all common ignition hazards in traditional mechanical flow switches.
