IEC335 China Manufacturer High-tech Enterprise Laboratory Fire Detector Test/Testing Machine
1. Product Description
The device is designed and manufactured according to the requirements of standards such as IEC335 and EN 54-10 point ultraviolet (infrared) flame detectors.
The burner uses a photosensitive element to control the on-off of the gas solenoid valve.
Including methane combustion furnace, 2m precision test track (optional), test source, shutter device. Ordinary type / computer type.
2. Standards
IEC335 and EN 54-10
3. Technical Parameters
1) burning furnace
| Flame height adjustment range |
1-5cm |
| The flame is burned at a horizontal distance from the center of the flame |
1.5m |
| The variation in illuminance |
≤ 5% |
| Flame extinguishing automatically cuts off the test gas source |
|
| The gas must use methane gas with a purity |
not less than 99.9% |
2) Light source modulation system
| Light-reducing film |
Neutral UV light-reducing film can pass ultraviolet radiation with wavelength greater than 200nm and less than 300nm (neutral infrared light-reducing film is optional). |
| Modulator (adjustable) |
The modulator consists of a dimmer and a dc motor. The d.c. motor drives the chopper to rotate at the desired frequency to modulate the radiation generated by the flame. (Checkout sensors and radiators are not included). |
| Twilight frequency |
10-100Hz |
| Drum radius |
70mm |
