Sensor location
The
Humi
Core
™
Pro
sensor is designed for continuous moisture measurement in production flow stream.
A prerequisite for correct moisture measurement in bulk materials is always to select the right place to in-
stall the moisture sensor. In connection with bulk material chutes or conveyor belts, you additionally have to
ensure that the material to be measured is fed over the sensor at a constant layer height.
4.1 Mounting in the screw conveyor
Mounting the moisture sensor in the screw conveyor has proven to be particularly advantageous since the
measured product is guided over the sensor at regular intervals with a constant thickness. The moisture
sensor has to be placed underneath the screw conveyor as depicted in Figure 4.

NOTE: In the case of hard bulk materials, the sensor surface is subject to a latent risk of material getting
stuck between the screw conveyor and the
Humi
Core
™
Pro
sensor. This can be prevented by cutting off
a small section of the spiral screw flight. (See Figure 5) As a substitute for the cutoff spiral, you can install
a rubber scraper that then performs the function of material transport.
