Open Path Gas Detector Meets LEL-Meter And PPM-Meter Requirements

With an advanced feature set, the new IR5500 open path gas detector from General Monitors meets agency performance requirements on both the LEL-meter and ppm-meter scales. The IR5500 is certified for operation at -55ºC and for FM approvals, EN, and IECEx performance standards.

The IR5500 open path gas detector provides continuous monitoring of combustible gas concentrations. The system consists of an IR source and receiver, which continuously monitors for methane in both the 0 to 5,000 ppm-meter and 0 to 5 LEL-meter range. Zero to 2,000 ppm-meter and 0 to 1 LEL-meter scales are also available for monitoring propane. The IR5500 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 IR5500's advanced infrared sensor technology features a single-beam detection design, which can improve accuracy and reduce drift. The design of the sensor includes continuous self-check monitoring for fail to safe operation. Automatic gain control compensates for dirty optics, rain and fog.
 
The IR5500 features a built-in display designed for simple installation and maintenance and lower total cost of ownership. The IR5500 requires no tools for alignment at any range and can be aligned without a scope at 100 meters or more. At installation, technicians can utilize the IR5500's integral display and adjustable mounting arms, which also eliminates bulky setup equipment.
