Product Description
XHT-3 ultraviolet flame detector is a kind of ultraviolet furnace flame detection device designed and manufactured according to gas safety standards and specifications. The flame detector consists of a processor and a probe. The processor and the probe are connected by two core twisted pair shielded cables.
1. Working principle: the light signal from the flame is transmitted to the UV photosensitive tube at the tail of the probe, and the UV photosensitive tube completes photoelectric conversion. The signal transmission between the probe and the processor adopts the current transmission mode to improve the anti-interference ability, and is transmitted to the processor through two core shielded cables. After the electrical signal is processed, the fire signal and no fire signal are output in the form of switch

4. Full series of XHT flame detector
XHT-1 Flame detector
The heat resistant probe detects flame with the ion generates during combustion. It is available for all kinds of gas boiler flame.
XHT-3 UV Flame detector
The UV sensor element is applied in this flame scanner. There is a dust proof lens at detector front. It is not focused on incident light, has lower requirement on cooling condition, and is applicable for the flame scanning of large and medium size oil and gas boiler.
XHT-5 Visible Light Flame detector
It is applicable for all fuel flame. The flame rigidity and pulse frequency is displayed. It is available for fault self-check, indication and signal output. This is a digital process scanner with newest technology software and hardware.
XHT-6 Digital Integrated Flame detector
It has three independent routes that detect target flame. It amplifies, detects and traces the flame rigidity and frequency to realize single nozzle scanner with multiple flame accompany. It is applicable for single burner and multi burner system with different load, fuel and combustion methods. The detector and signal amplifier are integrated together and realize convenience communication with control room.
XHT-8 Image Flame detector
It is new flame scanning device with reliable performance and is easy to handle. It consists of image detector, image processor, touch screen, and LCD displayer. The optics image technology and CCD camera are sensor elements that send flame images to screen through video distributor. Through another route, video is sent to image processor, which analysis the image data and output flame switch signals to relative protection system that is FSSS. Consequently, potential bugs and incident are eliminated and the unit efficiency is raised.
