What Is an Open Path Gas Detector?
An open path gas detector is designed to detect the presence of combustible gases in a relatively straight path and most commonly along fence lines. Therefore, they are vital for protecting the perimeter of your premises. Additionally, they may lead you to save costs, since these detectors have a long range and may cover a large fence line. For example, the FlexSight LS2000 line-of-sight (LOS) detector has an open sensing path 5 to 120 meters between transmitter and receiver.
Infrared Gas Detector Working Principle
The LS2000 is an infrared gas detector that measures the absorption of infrared light by specific gas molecules. To do this, the device has a transmitter module with a Xenon flash lamp, which produces a collimated infrared light source. This light source illuminates the path between the transmitter and receiver. As a side note, the transmitter uses a filter to block visible light emissions, so it is eye safe. When a hydrocarbon gas is present, it emits infrared radiation. Subsequently, the heat is detected from this deflected radiation, and the photosensitive material in the detector converts the incoming infrared radiation into an electrical signal. Different gases have different radiation absorption coefficients, which allows the detector to identify what gas is present. What this results in is extremely reliable and fast detection, with real-time measurements and automatic self-testing functionality.
