The Detcon IR-700-CH by Teledyne is a non-intrusive, “Smart” sensor designed to detect and monitor combustible hydrocarbon gases in the air over the range of 0-100% LEL, utilising miniature, non-dispersive Infrared Optical (NDIR) sensor technology, as compared to catalytic bead sensors. With NDIR, there is no risk of sensor poisoning, no risk of high-concentration saturation, and no need for oxygen to be present.
The plug-in, field-replaceable detector features oversized gold-plated connections that help prevent corrosion. The IR-700-CH’s rugged framework includes an electro-polished 316 stainless steel housing with fully encapsulated electronics and dual-layer surge protection. This innovative design virtually eliminates sensor failure due to water ingress, corrosion, vibration, and transient spikes.
A primary feature of the Model IR-700-CH is embedded intuitive software that simplifies the operator interface by guiding the user through routine calibration, configuration, and fault diagnostic functions using a built-in alpha/numeric display. The Model IR-700-CH is equipped with standard analogue 4-20mA and Modbus RS-485 outputs. Among its unique features is a wireless option that can be used with Detcon’s SmartWireless product line.
Additional integration options include a Remote Alarm Module (RAM) and HART. Detcon’s combustible gas sensor has an infinite shelf life and a 5-year warranty.
Suitable for Oil and Gas, FPSOs, LNG/CNG Plants, Refining and Petrochemical, Pulp and Paper Mills and Waste Water Treatment Plants.
Gas detected: Methane, Hexane, Ethane, Ethylene, Propane, Gasoline Vapour, Butane, Diesel Fuel Vapour, Pentane, Jet Fuel Vapour.
