HRP-T1000-C Infrared Fixed Combustible Gas Detector

Industrial Gas Monitoring Solution Based on NDIR Non-Dispersive Infrared Technology

HRP-T1000-C is an industrial-grade fixed combustible gas detector with NDIR detection technology, which is specially used to continuously monitor the concentration of combustible gas in industrial environment.

Different from the traditional catalytic combustion gas detector, HRP-T1000-C does not rely on oxygen to participate in the detection process, and can realize full range, high precision and long-term stable gas monitoring.

The equipment is especially suitable for monitoring combustible gas in oxygen-deficient environment, high-concentration gas environment and complex working conditions, and can be widely used in oil and gas, chemical industry, energy, electric power, environmental protection and special industrial places, providing reliable guarantee for safe production of enterprises.

What is an Infrared Combustible Gas Detector?

Infrared combustible gas detector is a kind of detection equipment which uses the absorption characteristics of gas to infrared light with specific wavelength.

Different gases will absorb infrared light with a specific wavelength. When the gas to be detected enters the detection cavity, the infrared light energy changes. The equipment calculates the gas concentration by analyzing the attenuation degree of the optical signal, thus realizing accurate detection.

Because the detection process does not need chemical reaction, infrared detection technology has higher stability, longer service life and stronger anti-poisoning ability.

Working Principle of HRP-T1000-C

HRP-T1000-C adopts advanced NDIR (Non-Dispersive Infrared) non-dispersive infrared detection technology.

Detection Process

The infrared light source continuously emits infrared light with a specific wavelength.
The gas in the environment enters the detection cavity.
Combustible gas absorbs infrared energy of corresponding wavelength.
The infrared receiver detects the change of light intensity.
The built-in microprocessor analyzes and calculates the signal.
The detection result is converted into real-time gas concentration data.
The concentration data is displayed in real time and uploaded to the control system through the communication interface.
When the concentration exceeds the preset alarm value, the equipment automatically starts the acousto-optic alarm and relay linkage output.

The whole detection process does not need to consume sensor elements, and can maintain stable detection performance for a long time.
