NDIR Technology Freon Sensor Principle Application

Freon is a common refrigerant, and there are many types of it, the common ones are R22, R32, R134a, and so on. Generally, Freon is an inert gas, and traditional electrochemical gas sensors make it difficult to detect Freon leaks. Nowadays, the more mature method is the NDIR principle to determine the concentration of Freon in space through the absorption of specific wavelengths of light by Freon gas.

NDIR Freon Sensor Principle

The Freon Sensor is a sensor based on the optical principle. It works by using Freon molecules to interact with a specific light source and determines the concentration of Freon in the environment by detecting changes in reflected or absorbed light. The light source in the sensor can be a radiation source such as a laser or LED, and the signal processing unit converts the reflected or absorbed light into an electrical signal through a photodetector, which is processed and judged.

How to use Freon Sensor?

Freon sensors usually need to be used in conjunction with alarms or other control systems to realize automatic monitoring and alarm functions. When selecting a Freon Sensor, factors such as the sensor’s operating range, sensitivity, stability, and response time need to be considered to ensure accurate and reliable detection.

Application of Freon Sensor in Environmental Monitoring

Freon Sensor is widely used in environmental monitoring mainly because Freon is a common organofluorine compound that is widely used as a refrigerant, fire extinguishing agent, various foams, and lubricants. However, due to its stable chemical properties, Freon is difficult to degrade naturally and therefore can cause damage to the ozone layer of the atmosphere, which can lead to a series of environmental problems. Freon Sensor can be used to measure the concentration of Freon in the environment to detect environmental problems in time and protect environmental health.

Application of Freon Sensor in Industrial Field

Freon Sensors are also widely used in the industrial field, mainly because Freon is widely used in various production processes, such as refrigeration, fluorine chemicals, semiconductor manufacturing, and so on. Freon sensors can perform real-time detection of Freon in the production process to ensure environmental safety in the production process and prevent accidents in the process. In addition, Freon sensors can also be used to monitor industrial exhaust gases to protect the environment.

In summary, the Freon sensor is based on the optical principle, through the detection of the concentration of Freon in the environment to carry out gas detection, with high sensitivity, fast response speed, and other advantages. It has been widely used in environmental monitoring and industrial fields.
