IR-522 Combustible Gas Sensor

Manufacturer: Teledyne| Detcon
Detcon Model IR-522 sensors are non-intrusive “Smart” sensors designed to detect and monitor Combustible Hydrocarbons over the range of 0-100% LEL (lower explosive limit). 

The sensor assembly consists of a miniature infrared optical sensor in a stainless steel housing that includes a splashguard with integral cal port, a plug-in control transmitter circuit, a base connector board and an explosion proof enclosure.
Features
