Infrared (IR) point sensor is one type of gas detectors.Infrared point sensors are usually made of tungsten alloy. Tungsten alloy infrared point sensors can be used to detect hydrocarbons and other infrared active gases such as water vapor and carbon dioxide. Tungsten alloy infrared point sensors are commonly found in waste-water treatment facilities, refineries, gas turbines, chemical plants, and other facilities where flammable gases are present and the possibility of an explosion exists.
Tungsten alloy infrared point sensors infrared point sensors use radiation passing through a known volume of gas; energy from the tungsten alloy sensor beam is absorbed at certain wavelengths, depending on the properties of the specific gas. Tungsten alloy infrared point sensor is advantageous because it does not have to be placed into the gas to detect it and can be used for remote sensing.
