Honeywell 2104B2111 Infrared Flammable Gas Detector

Honeywell 2104B2111 infrared combustible gas detector is a device produced by Honeywell for detecting combustible gas. The following is an introduction to it:

Working principle

Based on the principle of infrared absorption, the detector emits infrared light of a specific wavelength. When combustible gas exists, gas molecules absorb infrared light of a specific wavelength, causing the intensity of infrared light to change. The detector determines the concentration of combustible gas by detecting this change. This principle has high accuracy and stability, and can effectively avoid false alarms and missed alarms.

Product features

High-precision detection: Using advanced infrared sensing technology, it can accurately detect low-concentration combustible gases and can be used for the detection of a variety of combustible gases, including but not limited to natural gas, liquefied petroleum gas, hydrogen, etc.

High reliability: It has good anti-interference ability and can work stably in complex industrial environments, reducing false alarms caused by electromagnetic interference, temperature changes, humidity changes and other factors. At the same time, the equipment has a self-test function, which can automatically detect the working status of sensors and circuits, detect faults in time and send out alarm signals.

Fast response speed: It can quickly detect changes in the concentration of combustible gas and send out alarm signals in a short time, providing guarantees for timely safety measures.

Easy to install and maintain: Standardized installation interfaces and electrical connections are usually used, which is convenient for installation in different places. In addition, the maintenance cost of the equipment is low, and the sensor has a long service life, which reduces the frequency and cost of replacing the sensor.

Application scenarios

Industrial field: It is widely used in production sites of industries such as petroleum, chemical, natural gas, electricity, and steel to detect the leakage of combustible gases and prevent fire and explosion accidents. For example, in the device area and storage tank area of refineries and chemical plants, as well as along the natural gas transmission pipeline, combustible gas detectors need to be installed to ensure safe production.

Commercial field: It is suitable for gas use areas in commercial places such as hotels, restaurants, shopping malls, and office buildings, such as kitchens and gas boiler rooms, to monitor gas leaks and protect personnel and property safety.

Other fields: In some places where there may be a risk of combustible gas leakage, such as garages, warehouses, laboratories, etc., the detector can also be installed to improve the safety of the place.

Technical parameters

Detection gas: A variety of combustible gases can be detected, depending on the configured sensor, common ones are methane, propane, butane, etc.

Detection range: generally 0 - 100% LEL (lower explosion limit), which can be adjusted according to actual needs.

Alarm setting value: usually preset to 20% LEL and 50% LEL two-level alarm, which can also be customized according to user needs.

Response time: T90 response time is generally less than 30 seconds.

Working temperature: -40℃ - +70℃.

Working humidity: 0 - 95% RH (non-condensing).

Power supply: usually 24V DC, and other power supply methods can also be selected according to needs.

Output signal: generally 4 - 20mA analog signal, which can be easily connected to other control systems, and can also provide relay output for controlling sound and light alarms, exhaust fans, emergency shut-off valves and other equipment.
