EGE Elektronik Sensor for Explosive Productseries ST 110 KH

Description

EGE Elektronik Sensor for Explosive Productseries ST 110 KH is the authoritative choice for industrial applications where explosive risks and high thermal loads overlap. Designed for Zone 0 and Zone 1 (Gas) as well as Zone 20 and 21 (Dust), this sensor ensures that process monitoring does not become an ignition source, even when the medium is significantly heated. Operating on the thermodynamic principle, the ST 110 KH uses a solid-state probe to detect flow velocity. This technology is critical for hazardous zones because it contains no moving parts. Traditional flow switches with paddles or turbines can create mechanical friction, heat, or static electricity—all of which are potential ignition sources. The “KH” designation indicates the presence of a thermal decoupling neck, which physically separates the sensitive transducer elements from the extreme heat of the media, supporting continuous operation at 120°C.
