A flame detector is a fire protection device, which detects the flame in the place where it is fixed and issues an alarm thereby alerting nearby people to the danger of fire. In most of the manufacturing companies, furnace flame detector is used in order to detect and prevent fire. Flame detector responds either to radiant energy visible to the human eye or outside the range of human vision. Most flame detectors work either by optical flame detector or flame ionization detector but some of them use combination of both detectors.
Flame detector works at specific ranges, which uses optical sensors to record the incoming radiation at a particular wavelength. The energy radiated from the flame is electromagnetic radiation and it can be identified at various spectral ranges like UV, IR and VIS. Depending upon the sensor used there are number of flame detectors available they are infra red flame detectors, ultra violet flame detector, UV/IR, IR/IR and tripe IR spectral band detector. Flame detector has a cone of vision that defines the effective capability of sensing fire. It is inefficient for slow fires however it responds faster for rapidly developing fire like combustible gas and liquid. It is available in different shape and size.

A Bolometer.
To use the PLL (Phase Lock Loop) as FM detector, you need to know the Free-running frequency.
the lie detector
really old rapter
Most cutting and welding is done with a neutral flame.
How does a rain detector works
To test a UV flame detector, you can use a UV flashlight to simulate the presence of a flame by shining the light near the detector. The detector should respond by triggering an alarm or other designated response. It is important to follow the manufacturer's guidelines for testing procedures and frequency.
The normal color of the gas flame in a halide leak detector is blue. If the flame changes to a different color, it can indicate the presence of halides in the gas being tested.
digital signal
i think it detect the voltage left by the battery
Checking for gas leaks with a naked flame is dangerous because if there is a gas leak present, the flame can ignite the gas causing an explosion. It is safer to use a gas detector or soapy water to check for gas leaks.
You can try shaking it , it usually works
The flame detector on the pilot assembly is probably defective. If you do not know how to fix this, call you gas supplier and have it repaired.
I am not sure... But I would suggest using a metal detector. Hope it works!
The retention time of hexane in gas chromatography using a Flame Ionization Detector (FID) can vary depending on the specific chromatographic conditions such as column type, temperature, and flow rate. However, typically, the retention time for hexane using an FID ranges between 2-4 minutes on a non-polar column.
Flame Light Bulbs are light bulbs that are designed to look like flames or candles burning.Simple Electrical system. it works from electricity.
A flame eye in a boiler works by detecting the presence or absence of a flame in the combustion chamber. It uses a sensor that measures the UV light emitted by the flame. If the flame is extinguished, the flame eye will signal the control system to shut off the fuel supply to prevent unsafe conditions.
