What distinguishes portable gas detectors from fixed gas detectors?
According to different installation and usage methods, gas detectors can be divided into portable gas detectors and fixed gas detectors. Fixed gas detectors and portable gas detectors are convenient gas monitoring detectors developed for employees in different usage environments. What is the difference between a fixed gas detector and a portable gas detector?
Fixed gas detectors are commonly used in industrial equipment and production processes. Because fixed gas detectors can be installed on specific detection points to detect specific gas leaks.
The detection head composed of sensors and transmitters is installed on the detection site, and the secondary instrument composed of circuits, power supplies and alarm systems is installed in a safe place for staff to monitor.
Only in terms of process and technology, the measurement principle is the same as that of general detectors, but in terms of process and technology, it is more suitable for the continuity, long-term and stability required for fixed inspection. The application of fixed gas detectors should also be selected according to the type and concentration of on-site gases, and fixed gas detectors should be installed in locations where specific gases may leak. For example, the effective height of the sensor should be selected based on the weight of the particular gas.
Due to the simple operation and small size of the portable gas detector, it can be carried to different production locations and has a long working time. If the electrochemical detector is powered by alkaline batteries, it can be used continuously for 1000 hours; the new LEL detector, PID and composite instruments use rechargeable batteries, which can run continuously for nearly 12 hours. Therefore, portable gas detectors are widely used in various factories and health departments.
If you use a portable gas detector as a safety alarm in an open place, because it can continuously, instantly and accurately display the concentration of toxic and harmful gases on site, you can use a portable gas detector.
Following are the differences between fixed gas detectors and portable gas detectors. Although there are many differences between fixed gas detectors and portable gas detectors, they also have many things in common, such as simple operation and long-term measurement of specific gas content in the environment.
