Sniff IR Gas Detector
This stand-alone detector is a direct plug-in replacement for conventional catalytic-type units. But because of its design, it virtually eliminates the frequent costly and time-consuming calibration required with catalytic detectors.
The unit reacts swiftly to virtually any hydrocarbon gas- propane, methane, ethane, gasoline, kerosene and the like. This means that it is particularly efficacious for offshore platforms, pipeline systems, pumping stations, refineries, tank farms, petrochemical plants- or wherever hydrocarbon gases present a potential explosion problem.
To guard against false alarms, it uses two precision sensors tuned to different infrared frequencies. Any change- however slight- in the ratios between the two IR signals triggers an immediate alarm. Patented control algorithm automatically compensates for component aging and changing environmental conditions.
The unit's design uses simple optics- no mirrors or beam-splitters- for trouble free operation even in inclement atmospheres. Unlike catalytic models, it works in high hydrocarbon vapors or low-oxygen environments.
The unit measures 6½ inches long and 2½ inches diameter; input is 10/30 VDC, output 4-20 mA. Alarm relays can drive warning lights and sirens, turn on fans, close emergency doors, and bring help on the run.
