Honeywell 2108B4000N Infrared Gas Detector

Honeywell 2108B4000N infrared gas detector is a device launched by Honeywell for detecting specific gases. Here is some information about it:

Working principle

Based on infrared absorption spectroscopy technology. Different gas molecules have characteristic absorption of infrared light of specific wavelengths. When infrared light passes through the measured gas, the gas absorbs the light of the corresponding wavelength, which weakens the light intensity. The detector calculates the gas concentration according to the Lambert-Beer law by measuring the change in light intensity.

Features and advantages

High-precision detection: It can accurately detect the concentration of target gas without interference from other gases, and provide reliable data for gas safety monitoring in industrial sites.

Quick response: It can detect changes in gas concentration and issue an alarm in a short time, which helps to respond to potential gas leakage hazards in time.

Good stability: It has a rugged design and stable performance, and can operate stably in harsh industrial environments for a long time with a low false alarm rate.

Multiple gas detection: Different sensor modules can be configured to detect a variety of combustible or toxic gases, such as methane, propane, carbon monoxide, etc., to meet the needs of different industrial scenarios.

Easy maintenance: The structure and functions are designed to facilitate maintenance. The sensor is easy to replace. The equipment has self-diagnosis and fault prompt functions to reduce maintenance costs and time.

Technical parameters

Detection range: The detection range of different gases is different. For example, when detecting methane, it can generally cover a certain concentration range of 0-100% LEL.

Accuracy: It can usually reach within ±5% LEL, and can accurately detect slight changes in gas concentration.

Response time: The T90 response time is generally around 30 seconds to 60 seconds, and it can respond to gas leaks in time.

Working temperature and humidity: The working temperature range is generally -40℃ to +70℃, and the working humidity range is 0-95% RH (no condensation).

Output signal: Common output signals include 4-20mA analog signals, digital signals (such as HART, Modbus protocols, etc.), and relay outputs, which are convenient for connection with various control systems and alarm devices.
