261A1812P012 Overview of GE Flame sensors

I. Product overview

The 261A1812P012 GE Flame sensor is a device specifically designed to detect flames, which identifies the presence of a flame based on the spectral properties produced by the flame, particularly changes in the intensity of infrared and ultraviolet light. This kind of sensor has a wide range of applications in industry, fire safety and other fields.

Second, the working principle

Spectral detection: The flame sensor is capable of detecting infrared light in the range of 700nm to 1000nm, especially near 880nm with high sensitivity. In addition, some flame sensors can detect ultraviolet radiation below 400nm.

Signal conversion: The photosensitive element in the sensor (such as a photoresistor or photodiode) receives the light signal generated by the flame and converts it into an electrical signal. The strength of this electrical signal is proportional to the spectral intensity produced by the flame.

Signal processing: The converted electrical signal goes through processing steps such as amplification, filtering and analysis to determine whether there is a flame. These processing steps are usually completed by signal processing circuits.

Output control: Once a flame is detected, the sensor outputs a control signal to trigger the appropriate response, such as an alarm, turning off the circuit, or starting the fire extinguishing system.

Three, the main parameters

Detection distance: This parameter indicates the maximum distance at which the sensor can detect the fire source. The specific value depends on the sensor design and application environment.

Response time: This is the time required from the sensor detecting the signal generated by the fire source to the output of the signal to the control system. In general, the shorter the response time, the faster the sensor responds to the flame.

Operating voltage: The voltage required for the normal operation of the sensor. The exact value also depends on the sensor design and application environment.

4. Application field

261A1812P012 GE flame sensors have a wide range of applications in:

Industrial safety: Used in fire warning and protection systems, especially in flammable and explosive places, to detect and control fires in time.

Fire safety: In residential, commercial buildings and public places, it is used in automatic fire alarm systems to improve fire prevention and control capabilities.

Other areas: such as engines, boilers, furnaces and other flame alarm systems, as well as fire detection in robot competitions.

V. Summary

The 261A1812P012 GE flame sensor is a powerful and reliable flame detection device, which determines the presence of the flame by detecting the spectral characteristics generated by the flame and outputs the corresponding control signal. It plays an important role in industrial safety, fire safety and other fields, helping to improve fire prevention and control capabilities and reduce fire losses.
