EGE Elektronik Sensor for Explosive Productseries ST 111 K-L80

Description

EGE Elektronik Sensor for Explosive Productseries ST 111 K-L80 is the authoritative choice for facilities that operate in “permanently hazardous” areas. Unlike standard sensors, the ST 111 series is certified for Zone 0 (Gas) and Zone 20 (Dust), meaning it is safe for use where explosive atmospheres are present continuously or for long periods. The “L80” designation indicates an 80mm sensor length, providing the necessary reach to penetrate through pipe walls, welding sleeves, and thermal insulation to ensure the sensing tip is submerged in the core flow profile
