Brief introduction BN-VIF206H flue dust / transmittance detector, cross flue, double light path measurement system, by the launch, receiving system and thermal reflector. Transmitting and receiving system is provided with a high brightness LED as the light source, it emits a beam through the diffuser is projected to a spectroscope. The beam is divided into two parts: a part of light through the lens fired heat reflector, returned to be focused onto the detector measurements; another part is focused directly to the reference detector. By calculating the ratio of the signal intensity obtained on the two detectors, we can get the light transmittance or not through the photometric value, so the smoke concentration and dust concentration can be obtained indirectly. Features Direct and continuous measurement Small in size, light in weight, compact in structure Direct display of light transmittance or transmittance Pollution monitoring and compensating device with lens Automatic calibration and manual calibration, convenient and flexible The measuring path 0.55 meters Air purge path Long life LED signal light source No moving parts maintenance Simple installation and debugging Technical parameter Working principle: across the flue, dual / single path transmission Light source: high brightness LED Response time: 5 seconds to reach the final 98% Measurement range: light transmittance 0-99.99% Distinguishing rate: 0.01% To detect gases: smoke, methane, or related gases. Optical path length: 0.35 meters standard (other length can be customized) Average time: 1-59 seconds Calibration and calibration: manual calibration and calibration (with calibrator) Display: LCD liquid crystal display Analog output: 4-20mA current loop Digital output: RS485/232 Relay output: two way switch output (alarm value setting) Working temperature: -20 50 DEG C Working humidity: 0-99% (no condensation) Supply voltage: 220VAC; optional 12, 24VDC Power consumption: the maximum 18W transceiver system, thermal reflector 8W Vibration: 2Hz-60Hz maximum amplitude 2mm Shell material: Die Cast Aluminum Protection level: IP67
