MicroSafe IR-522

Model IR-522 is a “Smart” gas detection sensor designed to detect and monitor combustible gas in air over the range of 0-100% LEL (lower explosive limit) using matched-pair catalytic bead technology.

Model IR-522 features Detcon’s MicroSafe™ intelligent electronics, non-intrusive operator interface and comprehensive fault diagnostics. The sensor transmitter features an advanced universal design that fits all existing Detcon matched-pair catalytic bead sensors dating back more than 20 years. The sensor assembly includes the detector in stainless steel housing, a base connector board, an explosion proof enclosure (available in aluminum or stainless steel),a plug-in control transmitter circuit, and a splashguard with integral cal port. The packaging is Explosion Proof (Class I, Division 1, Groups C and D).

Model IR-522 is equipped with a standard analog 4-20 mA current signal equivalent to the sensor range of detection, one-man remote calibration, self-adjusting zero and span, and LED indicators for fault and calibration status. A HART communications option is also available. Detcon’s combustible gas sensor has an infinite shelf life and is supported by a 2-year warranty.
