Visibility sensor FT-N2

Measuring principle

Smog is composed of many tiny water droplets and various fine particles in the air. Infrared light emitted from the light source is scattered by the water droplets and detected by highly sensitive detectors. Within a certain range, the more water droplets or other tiny particles detected, the greater the scattered light intensity. Through the calculation of embedded software, the light scattering intensity is converted into the standard visibility value.

main feature

The transmitting and receiving unit and the controller unit are installed in the same chassis, which is small in size, light in weight, compact in structure, and easy to install and debug;

With automatic detection of optical pollution, correction and compensation; exceeding the warning value to send a maintenance alarm:

direct continuous measurement

No moving parts - low maintenance

Simple installation and debugging
