Product Overview and Industrial Role
The Honeywell 2104B2071 Short Range Transmitter Incl Conduit ATEX is part of the Searchline Excel open-path infrared gas detection system, designed for hazardous industrial environments requiring reliable flammable gas monitoring over short distances.
It operates as a transmitter unit paired with a receiver, forming a continuous infrared beam that detects hydrocarbon gas clouds across open areas. This model is specifically optimized for short-range coverage (typically 5–40 meters), making it ideal for compact installations such as process modules, tank farms, and congested plant layouts.
