The working principle and function of catalyst gas sensor
In manufacturing environments, it is crucial to have systems for detecting flames and toxic gases in research laboratories, water treatment facilities, and other buildings. From workers who spend hours in confined spaces to production workers handling sensitive equipment, the importance of these detection systems in protecting areas from these potential catastrophic threats is self-evident. However, when choosing a system for your facility, many factors may be affected, such as working conditions, system costs, installation process, etc. Therefore, for many companies that require industrial flame detection systems, the wisest choice is to install catalytic sensors.
Open Path Technology
The use of open path technology can scan large areas faster, and catalyst sensors are typically installed throughout the entire building, near areas where gas leakage or accumulation is most likely to occur, such as in narrow spaces or near pipelines, Valves and storage tanks. However, it is important to note that when determining the position of the sensor, it is better to avoid areas that may be exposed to hydrocarbons for a long time, as this may weaken the transmission signal of the sensor.
Independent monitoring
Although catalyst bead sensors work well in many facilities, some companies now prefer to use independent catalyst detectors that can be placed in a central position. In this way, a building only needs one monitor to scan for large areas of hazardous gas accumulation and leakage. However, if your company's budget is limited, please pay close attention to the type of detector purchased. For example, although magnetic bead sensors are relatively inexpensive and have a universal placement method, independent detectors may cost up to $10000 per unit, and placement guidelines may be more stringent.
Maintenance requirements
Like any type of gas detection equipment, catalyst monitors also have specific maintenance requirements to maintain high accuracy and reliability. This is particularly true for calibration methods, which require regular calibration by trained technicians or engineers. As these detectors will be placed in areas where chemical contamination issues such as chlorine may occur, technicians should regularly test the sensors by exposing them to small amounts of various gases. In this way, not only will the sensor remain active, but it can also transmit data in real-time to engineers for immediate analysis, ensuring that the sensor is in normal working condition.
Shock and vibration
When these detectors are placed in working areas with equipment, they may be subjected to varying degrees of impact and vibration. Although most detectors can withstand this situation, sometimes excessive shock and vibration can cause problems in the sensor circuit, increasing the possibility of occasional erroneous readings. To avoid this situation, it is better to place the sensor in areas with limited impact and vibration. In many cases, portable detectors are used instead of fixed monitors, especially in areas such as narrow spaces that are difficult to monitor.
