CO sensor solution expert

CO sensors are involved in all fields, such as commercial CO detectors, home fire alarms, vehicle fields, etc.

In the early stage of a fire, due to incomplete combustion, a large amount of carbon monoxide will be produced at the fire site. If the carbon monoxide concentration in the building is transmitted to the fire control center in real time, it is very important to guide fire rescue.

For reducing and avoiding cross gas interference, Winsen can help you.

CO sensor application scenarios

CO sensor application scenarios

CO sensors are mainly divided into civil fields and industrial fields. In the civil field, CO sensors are widely used in household CO alarms and domestic gas water heaters to detect carbon monoxide concentration in real time and prevent carbon monoxide poisoning. In the industrial field, carbon monoxide does not react with acids and bases at room temperature, but it can form explosive mixtures when mixed with air. Therefore, it is inseparable from the measurement of carbon monoxide concentration in petroleum and petrochemical, metallurgy, mining and other industrial places.

CO Sensor Guide

We have summarized the following questions to help you make better choices.

Question

What is the reason for the low data of the CO sensor (electrochemical type)?


Answer

Use inappropriate air source and gas path materials during the test. The measured gas is adsorbed on the gas path material, and the actual concentration decreases. We recommend using PTFE/PP/stainless steel material as the gas path to reduce the gas adsorption by the gas path. Please do not use strong adsorption pipes such as silicone tubes, copper tubes, and rubber. (Especially for the test of toxic gases such as NH3, H2S, CL2, etc., the test gas path must be of low adsorption material.)

 

Directly replace other brand products without calibration, the display is low due to the difference in sensitivity.

Question

What does the spring between the CO sensor electrodes do?


Answer

When the CO sensor (electrochemical type) is stored, we should short-circuit the working electrode and the reference electrode with a metal spring. Because when the sensor is not in use, there will be charge accumulation across the electrodes. We short-circuit it to release the charge and ensure the balance of the charge, which can greatly shorten the initial balance time of the sensor.

Question

Why is soldering prohibited when the CO sensor is installed?


Answer

The material of the outer package of the CO sensor (electrochemical type) is plastic. The high temperature when soldering can cause it to deform. In addition, thermal expansion and cold contraction lead to broken wires, destroying the sealing structure of the sensor, causing leakage and damage to the sensor.

We recommend that you solder the pins to the board first, then plug the sensor on the board.

Question

Why do CO sensors (semiconductor type) need to be aged?


Answer

This is determined by the characteristics of the semiconductor sensor. When it is put on hold (no power supply, normal temperature), water vapor and impurities will adhere to the surface of the sensor, which will affect the performance of the sensor. The sensor is heated by aging to remove the impurities attached to the surface of the sensor, so that the gas-solid interface of the sensor can reach the best state and maintain the activity and stability of the sensor.

Question

What problems should be paid attention to when using and storing CO sensors (semiconductor type)?


Answer

Exposure to silicon vapor, highly corrosive environments must be avoided.

Try to avoid high concentration environments.

Avoid contact with organic solvents (including silica gel and other adhesives), paints, chemicals, oils.
