General Monitors IR5500 Open Path Infrared Gas Detector

The General Monitors IR5500 is an Open Path IR Gas Detector that provides continuous monitoring of methane and propane gas concentrations. The system consists of an IR source and receiver which continuously monitors for methane and propane in both the ppm/m and LEL/M range.

The IR5500 IR Gas Detector provides two 4 to 20 mA analog signals proportional to each of the above ranges, in addition to a digital display and relay contacts. The General Monitors IR5500 is easily aligned using the digital display and adjustable mounting arms, therefore it does not require any bulky setup equipment (e.g. digital volt meters, handheld alignment aids). The IR5500’s sensitivity can be checked by placing a test gas film in front of the receiver.

The General Monitors IR5500 Open Path Infrared Gas Detector is calibrated at the factory and needs no further calibration. It also requires little maintenance save for a periodic visual inspection, test gas film check, and cleaning of the windows to assure dependable performance. Sensor data and status information from the IR5500 can be transmitted up to 9,000 feet to any industrial analog to digital (A/D) converter for use in multipoint computer-based monitoring.

Features
