1.2. Product overview
Dumo is a dust monitor based on particle charge transfer. It utilises the
experience and test data of the same technology Sintrol has developed and
perfected over almost two decades. The device has been developed for
continuous dust monitoring in industrial environment and it is equipped with three
colour LED indicating different dust concentration levels. Dumo is designed for
easy installation and operation.
1.3. Operating principle
Dumo measurement principle is based on the charge transfer of solid particles.
When solid particles enter into the flow channel, they interact with a sensor rod
and affect a small electrical charge. This charge provides a signal which is
proportional to the ambient dust level. Schematic diagram of the measurement
principle is presented in Figure 1.
