FRT Sentry Visibility Sensor

The visibility of the meteorological sense (MOR) is determined by the amount of light scattered by the suspended particles in the atmosphere (smoke, dust, fog, rain, snow). Through the measurement of the extinction coefficient, and then through the transformation of the standard formula will be able to obtain the desired value of human eye. Using the principle of pre scattering measurement (42 degree angle), which is recognized by the World Meteorological Organization, it can ensure a larger measurement range, which makes the detected data more representative.

FRT VREVisibility Sensor

FRT VRE visibility sensor is composed of optical transmitter, optical receiver and micro processing controller. The infrared transmitter receiver pulse light, simultaneous detection of atmospheric aerosol particles prior to the pulse of the scattered light intensity, all measurement information through the micro processing controller collects and mathematical model of specific algorithms into meteorological visibility. The visibility of a 12DC power detector and a three line RS232/RS-485 communication cable. The meteorological information and the state information are transmitted to the host computer through the communication interface.
