Scattered light dust measuring device, FW101 Ex

Главная » Продукция » SICK » Анализаторы » Dust Measuring Devices » Scattered light dust measuring device, FW101 Ex
 
 

The FW101 Ex is designed for continuous measurement of very low to medium dust concentrations - independent of the gas velocity, humidity, or charge of the particles. The probe design of FW101 Ex enables mounting on one side of the gas duct and does not require any mechanical adjustment or calibration with a dust-free measurement path. The measuring device can be used for a wide range of applications, including gas ducts with extremely small or large diameters, as well as thick and thin-walled stacks.
