Amphenol SGX Sensortech VQ600 Pellistor Gas Sensors for Hazardous Areas

Amphenol SGX Sensortech VQ600 Pellistor Gas Sensors for Hazardous Areas detect and monitor various gases from 0 to 100% LEL for combustible gases and 0 to 100% volume in thermal conductivity mode when using the SGX range of pellistor gas sensors. The VQ600 components are designed for use as an integral part of a fixed gas detection system. The head comprises a stainless steel flameproof enclosure constructed with an integral stainless steel sinter. This sinter allows the safe entry of the atmosphere being tested. Three types of mounting threads are available to allow easy fixing to the junction box of the fixed system and the facility to attach accessories to the sensor via an external M46 thread.
