Point source catalytic detector

Where overall large area coverage is necessary or desired, such as the monitoring of facility borders, pump alleys, entire onshore units or offshore modules, "line of sight" IR beam detectors are used, otherwise "point source", catalytic detectors are provided. The point source locations should be at least on either side of the leak point, which at least one of the detectors downstream ventilation pattern. 

Gas detection is provided in the process industries to warn and possibly prevent the formation of a combustible gas or vapor mixture that could cause an explosive overpressure blast of damaging proportions or initiate a fire. There are three types of gas detectors used in the process industries. The most common and widely used is the point source catalytic detector.
