The Model 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 in both the 0 to 5000 ppm meter and 0 to 5 LEL meter range. A 0 to 2000  ppm meter and  0 to 1 LEL meter range is also available for monitoring propane. The IR 5500 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 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 IR5500  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.
