How does a flame sensor work?

How does a flame sensor work?

A furnace flame sensor works by detecting the presence of a flame within the furnace. As the gas valve opens to begin the combustion process, the current is sent out from the sensor in order to detect the presence of heat from a flame.

Are there different types of flame sensors?

There are four primary optical flame-sensing technologies in use today: ultraviolet (UV), ultraviolet/infrared (UV/IR), multi-spectrum infrared (MSIR), and visual flame imaging. They are all based on line-of-sight detection of radiation emitted in the UV, visible, and IR spectral bands by flames (see Figure 1).

What is infrared flame sensor?

Infrared Flame Sensor / Infrared Flame Monitoring The pyroelectric detector of a flame sensor detects the typical spectral radiation of burning, organic substances such as wood, natural gas, gasoline and various plastics. In addition, burning produces water, which can also be detected in the infrared range.

What is the difference between a thermocouple and a flame sensor?

FLAME SENSOR VS. Thermocouples are used on standing pilot furnaces that have pilot lights. The thermocouple sits near the pilot light and gauges whether it’s working properly, while the flame sensor detects that the burners are lit once they start to emit gas and the igniters light them up.

What is the range of flame sensor?

760 nm to 1100 nm
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.

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

Where are fire flame detectors used?

Flame Detection Industrial and commercial applications include oil and gas pipelines, turbine enclosures, off-shore platforms, automotive manufacturing facilities, aircraft hangers, munitions plants, nuclear facilities, and many, many more.

How far can a flame sensor detect a fire?

IR3 detectors can detect a 0.1m2 (1 ft2) gasoline pan fire at up to 65 m (215 ft) in less than 5 seconds. Triple IRs, like other IR detector types, are susceptible to blinding by a layer of water on the detector’s window.

How to use a phototransistor to detect flame?

First Method: The first idea is to use a cheap phototransistor as the flame sensor which is very easy if you have quick access to the YG1006 high-speed NPN phototransistor. The 5mm phototransistor with probe angle of 60 degree can be used to sense flame or similar sparkles in 760 nm – 1100 nm wavelength.

What is a flame sensor and how does it work?

This sensor basically detects IR (Infrared) light wavelength between 760 nm – 1100 nm that is emitted from the fire flame or light source. The flame sensor comes with a YG1006 Phototransistor sensor which is a high speed and high sensitivity.

What is the function of a phototransistor?

Phototransistors are used in almost all electronic devices that depend on light including smoke detectors, laser-ranging finding devices, and optical remote controls. They detect visible, ultraviolet and near-infrared light from a variety of sources and are more sensitive than photodiodes.

What are the different types of IR flame sensor module?

Two types of IR Infrared Flame Sensor Module available in the market one having three pins (D0, Gnd, Vcc) and another one having four pins (A0, D0, Gnd, Vcc) both are can be easily used with Arduino and other microcontroller boards. Two types of flame sensors available in the market both types are consist of the same components.
