What are the common types and materials of gas detectors?
What is a gas detector? A gas detector is an important security equipment that detects the concentration value of gas leaks. Its installation and use can effectively prevent the harm caused by gas leaks to industrial production and life. It is an important industrial demand for users in related industries. So what are the common types of gas detectors and what are the differences between different types of materials?
1. Type of gas detector
According to type, they can be divided into fixed gas detectors and portable gas detectors.
Fixed gas detector: Fixed gas detector can be fixedly installed and used in flammable and explosive gas leakage sites and chemical plant areas where toxic and harmful substances exist. According to different detection gases, the current industry's high-quality electrochemical, infrared, catalytic combustion, Gas sensors based on thermal conductivity and PID photoion principles, Swiss high-precision capacitive digital temperature and humidity sensors, advanced circuit design, and mature kernel algorithm processing have achieved multiple software works and appearances. The products have the advantages of stable signals and high accuracy.
Portable gas detector: Portable gas detector is convenient for workers to carry around. It is mainly used for harmful gas detection, organic VOC gas detection, combustible gas detection, single gas detection and other gas tests. It can accurately detect early warning hidden dangers and detect precursors of accidents. Elimination applications are also becoming more widespread. Portable gas detectors can be divided into diffusion type and pump suction type according to their sampling principle. The so-called diffusion type means that the probe is placed in the dangerous zone of the gas detection, and the gas to be measured diffuses into the probe from the space, while the alarm is placed in the monitoring room to provide instructions and alarms. The pump suction type uses a pump to suck the gas to be measured into the detection probe. The suction pump is set together with the built-in gas detector. The detector is placed at a dangerous location of the gas to be measured to detect execution instructions and alarm functions.
What kind of detector users choose depends on their own needs. Fixed gas detectors under the same brand are more expensive than portable gas detectors. When choosing the type of gas detector, you need to choose based on It is determined by the company's own actual use environment, specific uses and specific needs for gas detection.
