Open Path Infrared Detector

Feb. 10, 2015

Get continuous monitoring of methane, propane, and other combustible gases with the Ultima Open Path Infrared Detector. The system consists of an IR source and receiver which continuously monitor 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 Ultima OPIR-5 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.

This infrared detector is calibrated at the factory and needs no further calibration. It also requires little maintenance except 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 receiver can be transmitted up to 9,000 feet to any industrial analog to digital (A/D) converter for use in multipoint computer-based monitoring. 

With multiple communication outputs, automatic gain control that compensates for dirty optics, and performance approval for harsh environments, this detector is a great solution for many applications such as compressor stations, drilling and production platforms, fence line monitoring, and fuel loading facilities to name a few. The Ultima OPIR-5 Detector 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).
