BK51Ex/IR3/闭路电视录像有三个带有红外线的火焰德

Brief IntroductionThe miniature color video camera integrated in the video IR3 infrared flame detector can not only help the user to determine the monitoring zone of the instrument in order to guarantee an optimal mounting position, but also carry out interconversion between the real-time transmission mode and the alarm start transmission mode. The detector adopts three infrared sensors sensitive to the infrared rays to detect the fire infrared radiation wavelength in a specific range. The programmable algorithm is adopted to check the proportion and correlation of the data received by the three sensors. A unique built-in microprocessor can ensure a very high immunity from false alarm. The detector is widely applicable to detection of flame of petrol, kerosene, diesel oil, aero oil, hydraulic oil and hydrocarbons like ethene, polyethylene, natural gas, commercial fuel gas, liquefied petroleum gas, methane, ethane, propane, etc. with the range of detection reaching 45m. The detector works in environmental extremes like high/low temperature, high dampness, knock, etc.Characteristics-Real-time color image transmission -High explosion prevention and dustproof grade -Long-distance detection -Detection in a 90 DEG wide taper zone -Real-time self-diagnosis function -Triple infrared IR3 spectral detection -Patented and industrialized contour design -Immunity from electromagnetic radiation -Adjustable sensitivity -Standard current output of 4-20mA, standard RS-485interface, passive contact outputTechnical ParametersBasic Technical Parameters -Monitoring Angle: ≤90° -Ambient Temperature: -40°C 70°C -Fire response time: <10S -Ambient Humidity: ≤95 percents RH(40 + 2°C) -Spectral Response: 0.7 1.0umIR,4.0 4.4umIR,5 6umIR -Detection Distance: 30m(0.1 square meterspetrol fire) -CCTC image: closed-circuit real-time image of the 0.1 square meters petrol fire alarm monitoring zone 30m away.Electrical Parameters-Operating Voltage: 18V 32VDC -Indicator Lamp: flash for normality and keep lighting for alarm - Operating Current: ≤20mA in a standby status (24VDC)≤40mA (24VDC)in an alarm status -Output Mode: relay output--------for normality: the contacts of the fault relay are normally closed,while the contacts of the 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 Rating of contact: 0.5A /125VAC 1A /30VDC 0.3A/ 60VDC 4-20mA Output-------For Fault: 0+0.5mA For Normality: 5 mA±10% For Early Warning: 12mA±10% For Fire Alarm: 18mA±10% RS-485 Output------- RS-485 standard interface for being connected with equipment such as controllers - Color video: Standard CATV interface, NTSC or PAL transformation, which are suitable for monitoring, recording and scanning carried out by various standard image apparatusesMechanical Characteristics-Cable Outlet Screw: standard 3-G3/4" (1"=25.4mm) - External Dimensions: 103mm×149mm×160mm(length × width × height) -Material: cast aluminum with stainless steel optional -Weight: <1.7kg(cast aluminum) <3.2kg(stainless steel)Certifications-Explosion Prevention Mark: ExdIICT6 -Dust Explosion Prevention Mark: DIP A21 TA,T6 -Protective Grade: IP65 -Model Inspection: In accordance with national standard of GB15631-1995 -Standards: GB15631-1995, GB3836.1-2000, GB3836.2-2000, GB12476.1-2000Applications-Chemicals--- production, storage and transportation -Electricity generation--- pump zones, machine rooms and unmanned zones -Explosive and munitions---storage, loading and unloading -Printing ---solvent treating, flattening and drying techniques -Waste disposal plants---processing, burning and storage of combustibles -Automobiles--- manufacture, spray booths -Paint--- manufacture -Warehouses--- storage of combustibles -Petrochemicals--- production, storage and transportation -Pharmaceutical industry -Petroleum and natural gas---exploration, production and storage -Offshore Oil Platforms -Coastal facilities--- refineries, charging stations and pipelines -Oil Depots---floating and fixed top grooves of oil depots -Hangar;Immunity
