N4 infrared gas sensor is an intelligent micro-gas sensor designed based on the principle of NDIR. It is used to measure the gas by the absorption characteristics of specific infrared spectra. The sensor is not dependent on oxygen and can not be poisoning like the catalytic sensor, The sensor has long life, high accuracy and stable performance.The sensor has both analog and digital signal output interfaces, which can output directly the gas concentration value signal with linearized treatment and temperature compensation, and is convenient to use.
Application
N4 infrared gas sensor is used to detect gases including methane, carbon dioxide and hydrocarbon gases, has a maximum range to 100%VOL. The sensor meets the requirements of GB 15322 Combustible Gas Detector, Non-dispersion Infrared Methane Sensor for AQ 6211-2008 Coal Mine and General Technical Conditions for Carbon 2 Sensor for AQ 1052-2008 Mine. It can be used for industrial plants, transportation tunnels, energy and power, petroleum and petrochemical, coal mine roadway, gas pumping and other dangerous environments, as well as more industrial environment health and safety monitoring.
The N4 IR gas sensor can working on the condition as below:
Operating temperature- - - - - - - - - - - - - - - (-40~ + 70) ℃;
Working humidity- - - - - - - - - - - - - -highest 98%RH, no condensation;
Atmospheric pressure- - - - - -80 to 120kPa;
Characteristic：
High resolution, 0-10%Vol range resolution of 0.01% and 10% -100%Vol range resolution of 0.1%
Has wide range for 0 to 100% Vol
Data output with linearity, temperature compensation
With both digital and analog signal output
Has wide range of working temperature for-40℃ to 70℃
Long-term stability, easy to calibration
No "poisoning" like the catalytic sensor
No dependent on oxygen
Intrinsic safety explosion-proof
