Use

MoistIQ is a state-of-the-art system designed for measuring online moisture in bulk solids. Measurement results can be used to control a dryer, automate humidification or to continuously monitor the process.

Function

The MoistIQ uses a capacitive measurement method, generating an electromagnetic field to detect changes in the dielectric constant and high-frequency attenuation of bulk solids. Because water has a significantly different permittivity than dry material, the system accurately infers total moisture content—not just surface moisture—in real time. Its sensor field penetrates up to 8 inches into the product, delivering highly reliable readings even in challenging industrial environments.

Mounting and Installation

SENSOR MOUNTING PROCEDURE :

Position the circlip on the waveguide regarding depth of the bushing + valve +
bracket + thickness of the pipe.
For optimal operation, the sensor head should be at least flush with the inside of the
pipe or slightly inside.
Use a depth gauge to determine the exact depth
Unscrew the headless screws of the blue holder bracket.
If you have a valve, open the valve to allow the passage of the waveguide.
Insert the waveguide sensor proper depth.
Secure the sensor with the screws.
