What types of gas detectors are there?
Diffusion type and pump suction type gas detectors operate on the same principles. The so-called diffusion type involves positioning the probe in the hazardous area for gas detection, allowing the gas to be measured to diffuse into the probe from the surrounding area, and installing an alert in the monitoring room to serve as a warning and alarm. The gas to be measured is pumped into the detection probe using a pump suction type. The gas detector built into the suction pump is configured together. In order to detect and carry out the instruction and alarm functions, the detector is placed at the hazardous location of the gas to be measured.
According to the type of detected gas, it can be divided into: toxic gas detector and combustible gas detector;
detectors that react to either a single or several amounts of flammable gas. A fully working combustible gas sensor transmitter is used in the detector's smart sensor. Among them, the infrared flammable gas detector is a great option in the following application environments: environments with a high frequency of high flammable gas emissions, anoxic environments, and environments where detection is difficult to achieve.
There are two types of gas detectors: pump suction gas detectors and natural diffusion gas detectors.
Diffusion gas detectors must be installed on-site because the gas in the detected area slowly flows the sample gas into the instrument with the free flow of air for detection. Low-pressure air sources cannot be detected using this method because it is sensitive to the detecting environment, which includes factors like ambient temperature and wind speed. The economic advantage of the diffusion gas detector over the pump suction type is that it is less expensive.
Pump-suction gas detector: The device has a gas sampling pump, which is powered by the power source. The gas is extracted and sampled by the gas sampling pump in the measurement area, and the sample gas is then sent into the device for detection. Pump-suction gas detectors are known for their quick detection times, extensive measurement ranges for hazardous areas, and maintenance of personnel safety. When the gas detector cannot be installed on the site or when there are specific requirements for response time and pressure difference, it is appropriate.
It can be divided into single gas detectors and all-in-one gas detectors depending on the quantity of detection. the
Using a single gas detector, which adopts a high-performance catalytic combustion sensor, it is possible to detect a variety of combustible gases, such as alkanes, liquefied petroleum gases, natural gas, hydrogen, and others, in the petrochemical, environmental accident, natural gas, liquefied petroleum gas, coal gas, and other industries.
A single, two-in-one, three-in-one, four-in-one, or optionally four poisonous gas sensors, as well as an additional single gas sensor to test, are all configuration options for an all-in-one gas detector.
