GTS MoistIQ - Continuous Inline Moisture Measurement for Bulk Solids
Real-time, inline moisture measurement (up to ±0.1% accuracy depending on material). Measures and averages up to 8” into the material for total moisture – not just the surface. Ideal for screw feeders, bins, conveyor belts. Maintenance-free, ceramic/Teflon/POM sensor surfaces. ATEX Zone 20/0 options available for Ex. User-friendly Windows software and intuitive calibration. Up to 24 calibration recipes can be stored, 16 of which can be selected via digital input. Long-term data logging, alarms, and Modbus integration. No lab delays – act instantly on moisture changes.
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.
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.
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.
