1. INTRODUCTION 

This manual describes how to install and use SINTROL digital triboelectric 
ambient dust monitor Dumo. 

Sintrol shall not be held liable for any loss or damage whatsoever arising 
from omissions or errors in this manual or any misuse of the product.  

1.1. Safety 

Dumo ambient dust monitor is virtually maintenance free. Under no 
circumstances should the user attemp to replace any components or the PC 
board. If, for some reason the monitor fails to operate, contact your local 
distributor or the manufacturer. 

It is essential that the unit is correctly grounded!  

(see section 3.)

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.
