How does a UV IR flame detector work?

How does a UV IR flame detector work?

A UV/IR flame detector consists of ultraviolet (UV) and infrared (IR) sensors that are joined together in a single apparatus. UV sensors work by detecting the UV radiation emitted by the flame and are sensitive to a wide range of flammable fuels including hydrocarbons, sulfur, hydrazine and ammonia.

What is a disadvantage of a combination UV IR fire detector?

A severe disadvantage is that almost all radiation can be absorbed by water or water vapour; this is particularly valid for infrared flame detection in the 4.3 to 4.4 μm region.

How does flame detector sensor work?

This type of flame detector works by detecting the UV radiation at the instant of ignition. Mostly all fires emit UV radiations, so in case of the flame, the sensor would detect it and creates a series of the pulse which is converted by detector electronics into an alarm output.

What part of the flame is UV detection?

In the emission spectrum of flames, there are some bands which are characteristic of their signature. These include: A “bump” in the UV radiation around 200 nanometers; and a near infrared and visible part between 0.4 and 3 microns, which is more or less intense, based on the nature of the fuel.

What is ultraviolet sensor?

UV sensors measure the power or intensity of incident ultraviolet (UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation, but is still longer than x-rays. UV sensors are used for determining exposure to ultraviolet radiation in laboratory or environmental settings.

How do you use a flame sensor?

Flame Sensor has three pins (some may have four pins): VCC, GND and DO. Connect VCC and GND to +5V and GND of the power supply (can be connected to Arduino’s +5V). the DO (short for Digital Output) is connected to Digital I/O Pin 11 of Arduino. In order to indicate the detection of a flame or fire, a Buzzer is used.

What are the specifications of a flame sensor?

The IR flame sensor is used to detect the presence of fire or other infrared source (Flame or a light source of a wavelength in the range of 760 nm to 1100 nm can be detected)….Specifications.

Range 760 nm to 1100 nm (Light Wavelength)
Power Supply
Phase Voltage 5V

How many volts should a flame sensor read?

Now we want to check flame sensor voltage. If the voltage is not within range there will not be enough electrical pressure to push the current through the flame. With your voltmeter, check the voltage between the sensor wire and the burner – it should be 90-107 volts AC.

Why choose detdet-Tronics for your flame detector?

Det-Tronics has designed and manufactured certified solutions (such as SIL 2/FM/CSA/ATEX/IECEx) for hazardous industrial fire and safety environments for over four decades. During this time, our flame detectors’ field-proven mechanical designs have protected customers’ sites for over 10 and, in some cases, up to 25 years.

What are the different types of optical flame detectors?

Our optical flame detectors combine sophisticated algorithms with detection technologies such as ultraviolet (UV), infrared (IR), UVIR, dual IR and multispectrum IR, to boost detection while minimizing false alarms. Which is the right detector for your application?

How does the Det-Tronics EQP work?

The EQP model is designed for use exclusively with the Det-Tronics Eagle Quantum Premier system. The detector communicates with the system controller over a digital communication network or LON/SLC (Local Operating Network / Signaling Line Circuit).

What are the x5200 flame detectors?

The X5200, X5200G, and X5200M UV Flame Detectors meet the most stringent requirements worldwide with advanced detection capabilities and immunity to extraneous sources, combined with a superior mechanical design. The mounting arrangement allows the UV and IR sensors to monitor the same hazardous location with a 90 degree cone of vision.
