HRP-H1000UVIR2 Flame Detector

HRP-H1000UVIR2 Point-Type UV/IR Flame Detector (hereinafter referred to as the flame detector) benefits from years of data accumulation and field installation experience, giving it advanced flame detection capabilities and a wide range of interfaces. Its rational structural design makes installation and wiring convenient. The 360° adjustable bracket allows the detection range to be adjusted at any time, providing convenience for subsequent maintenance and adjustment.

Multi-spectrum flame detection technology is one of the best solutions for timely fire warning. This technology detects fires by detecting the characteristic ultraviolet and infrared radiation emitted by flames, providing faster alarm response than traditional smoke or temperature-based fire detection technologies. Especially in open areas, the warning time can be greatly reduced. The flame detector uses high-performance photosensitive sensors combined with signal-processing algorithms built into the microprocessor to effectively distinguish real flame radiation from interference sources. While providing rapid fire alarm response, it also greatly reduces the impact of environmental factors such as moving objects, sunlight, lighting, and air conditioning on the detector, thereby significantly reducing false alarms.

HRP-H1000UVIR2 Point Ultraviolet/Infrared Flame Detector

Product Introduction

HRP-H1000UVIR2 point ultraviolet/infrared flame detector is an explosion-proof flame detection device specially designed for dangerous and industrial environments, which can detect open flames quickly and reliably.

The detector adopts the dual-spectrum flame detection technology of ultraviolet (UV) and infrared (IR), and judges the flame by identifying the characteristic radiation generated by the flame. The detection range of ultraviolet sensor is 180–260 nm, and that of infrared sensor is 3.8–4.3 μm. By analyzing the signals in two different spectral ranges, the reliability of flame identification can be improved and the possibility of false alarm caused by some non-flame radiation can be reduced.

The product has an infrared field of view angle of 90° and an ultraviolet field of view angle of 120°, and can be used for large-scale monitoring of industrial equipment, production areas, fuel storage facilities and other high-risk areas.

HRP-H1000UVIR2 supports DC24V power supply, relay output, 4–20mA output and standard RS485 communication, and can be flexibly connected to fire alarm system, industrial control system, emergency stop system and centralized safety monitoring platform.

The product is made of metal shell, the protection level reaches IP66, and the explosion-proof mark is Ex db IIC T6 Gb, which is suitable for dangerous industrial environment meeting the corresponding requirements.

Principle of Operation

HRP-H1000UVIR2 works based on UV/IR dual-spectrum flame detection technology.

When a flame occurs in the detection area, the flame will produce ultraviolet and infrared radiation in a specific band. The ultraviolet sensor detects ultraviolet radiation in 180–260 nm band, and the infrared sensor detects infrared radiation in 3.8–4.3 μm band.

The detector continuously analyzes the signals received by the two detection channels. When the detected radiation characteristics meet the preset flame recognition conditions, the detector judges that there is a flame event and starts the corresponding alarm output.

The basic detection process is:

Flame radiation → UV/IR sensor detection → signal processing → flame identification → alarm output.

The detector provides relay contact, 4–20mA analog signal and RS485 communication, which can transmit alarm status and monitoring information to external control and safety system.
