SMKBVIS-ECO Visibility Sensor
SMKBVIS-ECO visibility sensor is working based on forward scattering principle, It has robust, lightweight and compact structure, and can be mounted to vehicle for mobile monitoring. Aluminum alloy shell with spray-powder make it will never rust, applicable to drilling platforms, hips, highways and other transport sector.
The visibility meter adopts light forward scattering principle, built-in microprocessor-controlled atmospheric visibility monitoring equipment. It emits pulses of infrared light and measures the intensity of the forward-scattered light of the suspended particles in the atmosphere, using suitable algorithms to convert the measurements to meteorological visibility values.
Working Principle
When SMKBVIS-ECO is working, emitting module emits a bunch of infrared light with a center wavelength of 0.88μm through the infrared light emitting diode to the atmosphere, and the receiver converges a certain volume of atmospheric forward-scattered light onto the receiving surface of the silicon photoelectric sensor and converts strength of light to electrical signal, then signal is processed and collected by DAM(Data Acquisition Module), and then processed as visibility values by CPU and sent to PC via RS485.
Application
- Easy installation and start-up
- Analogue and digital Interfaces
