The difference between fixed gas detector and portable gas detector
Gas detectors can be divided into portable gas detectors and fixed gas detectors according to different installation and use methods. Both fixed gas detectors and portable gas detectors are developed for the convenience of personnel in different environments. What is the difference between a fixed gas detector and a portable gas detector?
In industrial installations and production processes, fixed gas detectors are generally used. Because the fixed gas detector can be installed on a specific detection point to detect specific gas leaks.
Most of the fixed detectors are two-body type. The detection head composed of sensor and transmitter is installed on the detection site as a whole, and the secondary instrument composed of circuit, power supply and display alarm device is installed in a safe place as a whole, which is convenient for staff to monitor. .
The detection principle of the fixed gas detector is the same as that of the ordinary detector, but it is more suitable for the continuous, long-term and stable characteristics required by the fixed detection in terms of technology and technology. The use of fixed gas detectors should also be selected according to the type and concentration of the on-site gas, and at the same time, attention should be paid to installing them in places where specific gases may leak, such as selecting the effective height of the sensor installation according to the specific gravity of the specific gas, etc. wait.
Because the portable gas detector is easy to operate and small in size, it can be carried to different production sites and has a long working time. For example, the electrochemical detector is powered by alkaline batteries and can be used continuously for 1000 hours; the new LEL detector, PID and composite The instruments use rechargeable batteries, so that they can typically work continuously for nearly 12 hours. Therefore, portable gas detectors are more and more widely used in various factories and health departments.
If it is in an open place, such as an open workshop using a portable gas detector as a safety alarm, you can use a portable gas detector that you can wear because it can continuously, real-time, and accurately display the concentration of toxic and harmful gases on site.
The above differences between fixed gas detectors and portable gas detectors are shared here for everyone. Although there are many differences between fixed gas detectors and portable gas detectors, they also have many things in common, such as easy operation and long-term operation. Detect the specific content of the gas in the environment to be tested.
