Жанғыш газды детекторлар қалай суық немесе жоғары температуралы ортада тұрақты жұмыс істеуге болады?

In many industrial fields such as chemical, petroleum, and gas, as a key equipment to protect production safety and personnel lives, the stable operation of combustible gas detectors is crucial. However, the two extreme environmental factors of extreme cold and high temperature are like "killers" hidden in the dark, threatening the performance and reliability of the detector at all times. Once the detector "fails" in an extreme environment and cannot accurately capture the traces of combustible gas leakage in a timely manner, it is very likely to cause catastrophic accidents such as fire and explosion, causing immeasurable economic losses to the company and even causing serious casualties. So, in the face of the many challenges of extremely cold or high temperature environments, how can we ensure the stable operation of combustible gas detectors? The following is the sharing of the editor of Zechuan Technology.

In extremely cold or high temperature environments, ensuring the stable operation of combustible gas detectors requires equipment selection, protective measures, regular maintenance, etc. The following are specific measures:

1. Guarantee measures in extremely cold environments

1. Temperature compensation: Use a temperature sensor to measure the ambient temperature and correct the measurement results to avoid the influence of temperature on the measurement and ensure the accuracy of gas concentration measurement.

2. Insulation treatment: Use insulating materials to wrap the detector shell to reduce temperature conduction, maintain the normal working temperature of the instrument, and prevent low temperature from causing reduced sensitivity or false alarms.

3. High sensitivity design: Improve the instrument's ability to detect low-concentration gases, and ensure that leaks can be found in time when low temperature causes gas concentration to decrease.

4. Regular calibration: Since cold environments may affect the stability of gas concentrations, the instrument needs to be calibrated regularly to ensure the accuracy of measurement results and timely response.

II. Safeguards in high-temperature environments

1. Comply with temperature range limits: Use strictly according to the maximum operating temperature specified in the instrument manual to avoid high temperature damage to the sensor or affect measurement accuracy.

2. Shorten exposure time: Reduce the continuous use time of the instrument in a high-temperature environment, and transfer it to a low-temperature environment for cooling after use to reduce the risk of component damage.

3. Calibration and maintenance: High temperature may change the calibration status of the instrument. Calibration is required in time after use to ensure that the measurement results are accurate and reliable.

4. Protective measures: Reduce the impact of high temperature on the instrument through sunshade, heat insulation and other means, such as using a sunshade or heat insulation board outdoors.

3. General safeguard measures

1. Protection level adaptation: Select instruments with high protection levels (such as IP65 and above) to effectively resist dust and water vapor intrusion and adapt to complex environments.

2. Anti-interference design: Use electromagnetic shielding shells and filter circuits to reduce the interference of strong electromagnetic fields and radio signals on instrument circuits and ensure data transmission stability.

3. Regular maintenance: Establish a regular inspection mechanism, clean the sensor filter, check the connection lines, and replace aging parts in time to ensure long-term stable operation of the instrument.

In summary, although the extremely cold and high temperature environment has brought many difficulties to the stable operation of the combustible gas detector, through scientific and reasonable equipment selection, effective protective measures and rigorous and meticulous maintenance, we are fully capable of building a solid "protective wall" for the detector to ensure that it can still work accurately and reliably under extreme conditions. This is not only a high degree of responsibility for the safe production of the enterprise, but also a solid protection for the life safety of every employee. Let us pay attention to every security detail, let the combustible gas detector continue to play an important role as a "safety sentinel" in extreme environments, escort the safe production of enterprises, and jointly create a safe and stable production environment.
