What are the specifications of a flame sensor?
Operating voltage: 4.75 – 5V max. Working current: 20 mA. Spectral bandwidth range: 760 – 1100 nm. Detection range: 0-1 m.
How do I choose a flame detector?
Flame Sensing Technologies Detection instruments should always be selected to suit the requirements of the application which commonly include fuel type(s), fire size, maximum detection range, Field of View limits, fire alarm response time, and potential nuisance or false alarm sources.
What are the different flame detectors?
There are three types of flame detectors currently available. They are Infrared (IR), Ultraviolet (UV), and a combination of UV and IR.
What is the purpose of a flame sensor?
The flame sensor in your furnace is a safety device that ensures the gas that fuels your furnace is being burned and not escaping into the vent system. The sensor detects when a flame is burning inside the burner assembly of your furnace.
What is the use of flame detector?
A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection.
How does a UV IR flame detector work?
Ultraviolet flame sensors work within wavelengths of no more than 300 nm. Within 3-4 milliseconds, ultraviolet flame sensors can detect explosions and fires by measuring the levels of radiation in the atmosphere (additional radiation is emitted at the moment of ignition).
What kind of light does a flame sensor detect?
The flame sensor can detect flame and infrared light sources with wavelengths ranging from 760 nm to 1100 nm. The flame sensor can detect flame and infrared light sources with wavelengths ranging from 760 nm to 1100 nm. It uses the LM393 comparator chip, which gives a clean, stable digital output signal and driving ability of 15 mA.
What is the wavelength range of the Grove flame sensor?
Based on the YG1006 high speed, high sensitive NPN silicon phototransistor, the Grove – Flame Sensor is one that’s capable of detecting fire source or other light sources in the 760nm – 1100nm wavelength range!
How long does it take for a flame sensor to work?
Within 3-4 milliseconds, ultraviolet flame sensors can detect explosions and fires by measuring the levels of radiation in the atmosphere (additional radiation is emitted at the moment of ignition). Unfortunately, false alarms are fairly commonplace.
How does a near IR flame sensor work?
Near IR array flame sensors, which are also known as “visual flame detectors”, boast flame recognition technologies. These sensors confirm the presence of flames by “reading” near IR radiation via the pixel array of a CCD.
