Humidity Measurement System
The device for measuring the moisture content of bulk materials (hereinafter referred to as the device) is intended for technological control of the mass of sheet and bulk materials during their manufacture on specialized equipment.
The one-sided humidity sensor (hereinafter referred to as the DVO) is used at enterprises as part of a complex of means for controlling material parameters.
The system includes a control and display panel, as well as an optical sensor for measuring the moisture content of bulk materials of paper or cardboard.
It is possible to connect up to 4 sensors to the panel simultaneously.
The connection range without special modules is up to 30 meters from the sensor to the panel.
