爆炸的证据的高速火焰探测器

Brief IntroductionExplosion-proof High Speed Flame Detector, designed on basis of principle that combining IR and UV spectrum with flame flash frequency, adopts dual microprocessor to monitor the flame spectrum and frequency in high speed with sophisticated software algorithm to ensure high speed response and reliability of detector. The detector possesses high explosion-proof and dustproof grades with strong self diagnosis function and electromagnetic immunity. It is widely applicable to high-risk places like processing industries of military gunpowder, ammunition, fuse, and priming system, etc. Characteristics- UV&IR duplex detection and multifrequency diagnosis- High explosion prevention and dustproof grades- MS response speed - Real time self diagnosis function- Detects hydrocarbon and non-hydrocarbon flame- Patented and industrialized contour design- Operation with a wide range of temper -Detection in a 120 DEG cone of visionTechnical ParametersBasic Technical Parameters- Spectral Response: 185 260nm UV; 4.3umIR - Fire response time: <150ms- Monitoring angle: ≤120° - Ambient Temperature: -40°C 70°C- Ambient humidity: ≤95%RH(40 + 2°C)- Detection distance: 25m(0.1 square metersstandard normal heptane fire)Electrical Parameters- Operating voltage: 18V 32VDC- Indication lamp: flash for normality and keep lighting for alarm- Operating current: ≤20mA(24VDC)in a standby status ≤35mA (24VDC)in an alarm status- Output mode: relay output---for normally: the contacts of the fault relay are normally closed. While the contacts of fire alarm relay are normally open. For fault: the contacts of the fault relay become normally open from the normally closed status For alarm: the contacts of the fire alarm relay become normally closed from the normally open status Capacity of contact: 0.5A/125VAC 1A /30VDC 0.3A/ 60VDC4-20mA output ---For fault: 0+0.5mA normally: 5mA±10% fire alarm: 18mA±10%RS-485 output --- RS-485 standard interface for being connected with equipments like controllerMechanical Characteristics- Weight: <1.7kg(cast aluminum) <3.2kg (stainless)- Material: cast aluminum with stainless steel optional- Cable outlet screw: standard 3-G3/4" (1"=25.4mm)- External dimensions: 103mm×149mm×160mm(length × width × height)Certifications- Explosion prevention mark: ExdIICT6 - Dust explosion proof mark: DIP A21 TA,T6- Model inspection: In accordance with national standards of GB15631-1995 and GB12791-2006- Protective Grade: IP65- Executive standard: GB12791-2006, GB15631-1995, GB3836.1-2000, GB3836.2-2000, GB12476.1-2000
