Interpretation of the cause analysis of the carbon dioxide sensor failure phenomenon and elimination method

The carbon dioxide detector detects carbon dioxide in the environment of the field through the principle of absorption of the infrared light source. The infrared detector uses the principle of infrared light source absorption to detect flammable hydrocarbon gases in the field environment.

 Methods for analyzing and troubleshooting carbon dioxide detector failures:
1. Insufficient charge or the battery has reached the end of its life. Check the charging cradle to make sure that the charging cradle contacts are in good contact or replace the battery. During maintenance, the model, specifications and parameters of the original circuit components should not be changed, and the original case should not be modified. All repairs must be carried out by pit personnel. If the user cannot repair it, it can be returned to the factory for repair or rlocation. 2. Insufficient working hours.
3. The alarm is silent and the contact is bad or the circuit is faulty. Check solder joints, wires and circuits.
4. The digital tube is missing or not bright. The digital tube is broken or the solder is loose. Replace nixie tube or repair welding.
