Detcon Model IR-700-CH is a non-intrusive “Smart” sensor designed to
detect and monitor combustible hydrocarbon gases in air over the range of
0-100% LEL using 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 O2 to be present. The plug-in, field replaceable detector features
over-sized 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 protec-
tion. 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 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 analog 4-20mA, and ModbusTM
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), HART, Foundation Field-
bus, and Profibus. Detcon’s combustible gas sensor has an infinite shelf life
and is supported by a 5-year pro-rated warranty.
