Industrial Combustible Gas Alarm

In the process of industrial use of combustible gas, if the combustible gas is in an incomplete combustion state or has gas leakage, etc., the combustible gas will cause personnel poisoning or fire accidents, directly threatening the life safety of personnel. Therefore, it is necessary to install an industrial-grade gas alarm. If the gas exceeds the standard in the on-site environment, the alarm can give an early warning, thereby reducing the probability of danger.

There are many types of combustible gases in the industrial field. Generally speaking, sensors are used in portable detectors or online detectors. There are also various options for different detection objects and application.

The infrared principle is suitable for the detection of hydrocarbons.

The catalytic principle is suitable for the detection of combustible and explosive gases or organic vapors within the lower explosion limit of petroleum, chemical and other industrial fields.

Winsen technology industrial gas sensor has a wide range, multi-range optional, high sensitivity, and a variety of sensors have passed the explosion-proof certificate. Detectable gases include: alkane gases, enyne gases, organic vapors such as alcohols, ethers, aldehydes, ketones, benzene, toluene, xylene, gasoline, and diesel.

What is the Difference Between Semiconductor Sensors and Electrochemical Sensors?

There is no good linear correspondence between the gas concentration and voltage of the semiconductor sensor, and it is generally only used for fixed-point calibration products; there is a good linear correspondence between the gas concentration and the output current of the electrochemical sensor, and can be made into quantitative detection products.

What Are the Precautions for Manual Soldering of Semiconductor Sensors?

1. Flux: rosin flux with the least chlorine; 2. Constant temperature soldering iron; 3. Temperature: 250℃; 4. Time: no more than 3 seconds.
