GTH500 Carbon Monoxide Sensor Working Principle of GTH500 Carbon Monoxide Sensor

Description :

　　Introduction to GTH500 Carbon Monoxide Sensor GTH500 Carbon Monoxide Sensor is a high-precision instrument that can be used for continuous detection of carbon monoxide concentration in coal mines. Sensors can measure and display the concentration of carbon monoxide underground in coal mines in real time, and can emit sound and light alarm signals when the set concentration value exceeds the limit, while outputting analog signals corresponding to the concentration of carbon monoxide. The GTH500 carbon monoxide sensor is suitable for measuring the concentration of carbon monoxide in the air in various workplaces underground coal mines. The sensor has infrared calibration function; It has over limit sound and light alarm functions. In addition, due to the lack of adjustment holes and parts that need to be adjusted in the sensor, the sealing performance is better and the operation is more reliable. Sensors have multiple signal output formats and can be used in conjunction with various monitoring systems in China. GTH500 Carbon Monoxide Sensor Model Meaning Model: GTH500 Carbon Monoxide Sensor

　　Working voltage 12-21VDC

　　Intrinsic safety parameters: Ui 21V Ii 75mA Ci: 0.5nF Li: 0mH.

　　The storage temperature is (-40-60) ℃.

　　Function Introduction of GTH500 Carbon Monoxide Sensor

　　After the sensor is powered on, the version information of the microcontroller software is displayed, and the sensor performs a self check internally. After the self-test result is normal, the sensor enters the working state and displays the concentration of carbon monoxide.

　　After the sensor enters normal working state, it can be calibrated or set alarm points. The calibration of the sensor should be carried out after the sensor is powered on and preheated for 30 minutes.

　　When the sensor and the matching device are connected normally, the red diode on the sensor display board will emit red light, indicating that the sensor and the matching device are connected normally.
