EGE Elektronik Sensor for Explosive Productseries ST 110 K-L80

Description

EGE Elektronik Sensor for Explosive Productseries ST 110 K-L80 is the authoritative solution for monitoring flow in volatile industrial sectors where standard probe lengths are insufficient. The “L80” designation refers to the sensor’s 80mm total length, providing a deeper reach into the process stream to ensure the measuring tip is positioned in an area of stable, representative flow. Operating on the thermodynamic principle, the sensor utilizes a solid-state probe that monitors flow velocity by measuring heat dissipation. This method is exceptionally safe for explosive zones because it contains no moving parts, thereby eliminating the risks of mechanical friction, sparks, or static electricity—common ignition hazards in traditional mechanical flow switches.

Features

Extended 80mm Probe (L80): Optimized for large pipe diameters, insulated piping, or deep welding sleeves.
ATEX / IECEx Certified: Approved for hazardous gas atmospheres (Zone 1) and combustible dust (Zone 21).
Intrinsically Safe (Ex i): Engineered to operate at energy levels below the ignition point of flammable mixtures.

Applications

Insulated Piping Systems: The 80mm length allows the sensor to bypass thick thermal insulation and welding sleeves.
Large Diameter Pipelines: Ensuring the sensor tip reaches the center of the flow profile for accurate detection.
Chemical Processing: Monitoring solvent flow in hazardous zones where corrosion resistance is vital.
