EGE Elektronik Sensor for Explosive Productseries ST 111 KH-L140

Description

EGE Elektronik Sensor for Explosive Productseries ST 111 KH-L140 is the authoritative choice for facilities that require uncompromising safety and maximum probe length. While standard sensors are often restricted to Zone 1, the ST 111 series is specifically built for Zone 0 (Gas) and Zone 20 (Dust), allowing it to be submerged directly into tanks and pipelines where flammable vapors are a constant condition. The “L140” designation refers to the 140mm sensor probe. This extended length is essential for reaching the core of large-diameter pipes or bypassing extreme thermal insulation jackets and deep mounting nozzles. By ensuring the sensor tip is positioned in the center of the flow stream, the ST 111 KH-L140 provides the most accurate data for critical process control.

Features

Ultimate Ex-Protection (Zone 0/20): Approved for use where explosive atmospheres are present continuously.
Extra-Long 140mm Probe (L140): Optimized for the largest pipelines and deep-nozzle/insulated installations.
High-Temperature Endurance (KH): Engineered for continuous flow monitoring in media up to 120°C.
Thermodynamic Measurement: Solid-state design with zero mechanical wear, jamming, or friction-induced sparks.

Applications

Large-Scale Refining: Monitoring hot solvent and fuel flow in large-bore pipelines in Zone 0 areas.
Chemical Distillation: Precise flow monitoring in heated, highly explosive columns.
Heated Storage Tanks: Monitoring flow in tanks for bitumen or volatile reagents where vapors are permanent.
Insulated Process Trunk Lines: Reaching through heavy cladding to monitor pre-heated fluids in hazardous zones.
