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.

Is the Dust Sensor Wired when Shipped?

Laser dust is wired, infrared dust is not wired.

How to Install and Place the Infrared Dust Sensor?

It must be installed vertically. Keep away from artificial air flow such as fans. When used in air purifiers, the front and rear of the fan cannot be installed. Optionally install it on one side of the shell, but keep vents on the shell to ensure that the external air can diffuse in.

Can the Two Voltages of Mq-7 Exist All the Time, or Do They Need to Be Powered Alternately? if It is an Alternate Power Supply, What is the Appropriate Power Supply Time?

It requires alternate power supply. Please check the information on the product manual. This sensor is powered by 1.5V and 5V alternately. The low temperature and low voltage (1.5V) state can detect CO, and the high voltage (5V) is the desorption process. The recommended 5V voltage duration is 60s, 1.5V voltage duration is 90s to alternately supply power. Since it is a desorption process at 5V, it is normal for the voltage to drop when CO is 150ppm.
