2108N4000N | Honeywell Optima Plus Gas Detector
It operates based on the infrared - absorption spectroscopy technique. Different gas molecules have characteristic absorptions for specific wavelengths of infrared light. When infrared light passes through the gas to be measured, the gas absorbs the light at the corresponding wavelength, causing the light intensity to decrease. The detector calculates the gas concentration by measuring the change in light intensity according to the Lambert - Beer law.
- High - Precision Detection: It can accurately detect the concentration of the target gas with high sensitivity, and is hardly affected by other gases, providing reliable data for gas - safety monitoring in industrial sites.
- Rapid Response: It can quickly detect changes in gas concentration and send out alarms, helping to respond in a timely manner to potential gas - leakage hazards.
- Good Stability: With a robust and durable design, it can operate stably in harsh industrial environments for a long time, with a low false - alarm rate.
- Versatile Gas Detection: It can be equipped with different sensor modules to achieve the detection of various combustible or toxic gases, such as methane, propane, and carbon monoxide, meeting the needs of different industrial scenarios.
- Easy Maintenance: It is designed with user - friendly maintenance features. The sensor is easy to replace, and the device has self - diagnosis and fault - indication functions, reducing maintenance costs and time.
- Detection Range: Varies depending on the gas being detected. For example, when detecting methane, it generally covers a concentration range of 0 - 100% LEL.
- Accuracy: Usually within ± 5% LEL, which can accurately detect small changes in gas concentration.
- Response Time: The T90 response time is generally between 30 seconds and 60 seconds, which can respond in a timely manner to gas leaks.
- Operating Temperature and Humidity: The operating temperature range is generally - 40℃ to + 70℃, and the operating humidity range is 0 - 95% RH (non - condensing).
- Output Signal: Common output signals include 4 - 20mA analog signals, digital signals (such as HART, Modbus protocols), and relay outputs, which can be easily connected to various control systems and alarm devices.
