Description:
SF6 gas sensor module adopts non dispersive infrared technology, which has the characteristics of high sensitivity, high resolution, oxygen free dependence, stable signal, accurate measurement, low power consumption and long service life. SF6 gas sensor module has diffusion type and pump type, which can be selected according to the demand.
Sensor principle:
(1)Using NDIR technology
After the infrared radiation emitted by the infrared light source is absorbed by a certain concentration of the gas to be measured, the spectral intensity proportional to the gas concentration will change. The concentration of the gas to be measured can be inversed by calculating the change of the spectral intensity;
(3)The principle of NDIR is adopted
The advanced optical path, precision circuit and intelligent software are combined to form a universal infrared SF6 sensor.
Features:
(1)Large scale monitoring
The good selectivity of SF6 gas sensor module makes up for the deficiency of traditional electrochemical sensor in the selection of high range test range.
(2)Fearless of harsh environment
With imported infrared light source and dual channel pyroelectric measurement, and automatic temperature compensation function, stable and reliable measurement results can be obtained even under harsh temperature and environmental conditions.
(3)Long life
Compared with the traditional electrochemical sensor, NDIR sensor has no obvious consumption and long service life.
(4)Zero calibration function
It is convenient for users to calibrate the zero point.
Application:
SF6 gas sensor module is widely used in flue gas emission, power industry, freezer, metallurgical plant and other scenes.
