Red-ultraviolet flame detector test set

1. Equipment size:L*W*H:2780mmx530mmx1370mm
2.Optical track:Double motorized displacement track to ensure large load and high displacement accuracy.
3. Load: 20KG.
4.Displacement precision:0.5mm.
5.Length:2m.
6.Straightness:less than 0.04mm.
7. Flame height adjustment range:1-5cm.
8. 1.5m from the center of the flame at the level of combustion illuminance changes ≤ 5% (user-provided illuminance meter).
9. Test flame: the use of purity of not less than 99.9% of the methane combustion flame. In the test process, the light source radiation energy changes should not be greater than ± 5%
10. Scrim: neutral infrared scrim, through the wavelength greater than 850nm, less than 1050nm of infrared radiation, its transmittance rate depending on the specific test requirements (configured according to product characteristics)
11. Chopper chopping frequency: 10-15Hz (when in use, you can continuously adjust the chopping frequency, when not in use, the chopper automatically rotates to the stop position, without blocking the light path)
12. Modulation disk radius: 70mm
13. Modulator: the modulator consists of light chopper and DC motor.
14.The DC motor drives the light chopper to rotate at the required frequency to modulate the radiation generated by the flame combustion.
