IR25TT-M Application Field and Working Principle

Gas sensors are important tools utilized in the detection and measurement of combustible, hazardous, poisonous, or hazardous gases in numerous different industrial and scientific applications. The IR25TT-M is a gas sensor model engineered to detect a wide range of hazardous gases including methane, propane, butane, and ethylene. Beyond being widely used in residential and commercial applications, this gas sensor can be seen in medical, automotive, scientific, environmental, and aerospace applications. This gas sensor works through the detection of combustible gases with an infrared absorption curve. The sensor is tailor designed with a special patterned optical filter to produce a curve which allows it to detect the desired gas. This curve, known as an absorbance curve describes a molecule’s ability to absorb light at certain wavelengths. In terms of the IR25TT-M, this gas detector is specifically engineered to detect combustible gases by focusing on the wavelengths of infrared light they absorb. The IR25TT-M specifically contains three main components: the detector IC, the infrared diode, and a thermistor. The thermistor is an electrical component utilized to measure temperature changes and assist in the calibration of temperature drifts. The infrared diode is used to generate the infrared light and the detector IC is the main component which analyzes the absorbance of the desired gas. To determine gas concentration, the gas sensor relies on the system’s sensitivity to the absorbance curve. When a combustible gas is detected, the absorbance of the infrared light increases. The detector IC digitizes the information from the absorbance curve and then adjusts the sensitivity of the system. The increased absorbance is then amplified within the IC and sent to the system’s output. These outputs are then converted into signals to indicate the presence of the targeted gas. The most attractive features of the IR25TT-M gas sensor are its low power consumption, high sensitivity, high accuracy, and wide dynamic range. This gas detector is incredibly efficient, consuming only 0.1mA of electricity during normal operation. The continual measurement of this sensor is incredibly precise and accurate due to the calibration of the thermistor. Lastly, its wide dynamic range allows the gas detector to accurately sense tiny gas concentrations and large concentrations of gas. Due to its various features, the IR25TT-M gas sensor is a valuable tool utilized in a variety of industrial and scientific applications. From medical, automotive, and scientific research applications to residential and commercial applications, this gas sensor model is an incredibly practical resource in the detection and measurement of combustible gases.
