Name:Continuous Inline Moisture Measuring System
Type:HUMY3000
Introduction:

The moisture in solids is an important parameter which strongly influences the quality of the product and can increase the economic efficiency of a production fundamentally. HUMY3000 is in many processes successfully in use, e.g. for sugar, tobacco, grain, malt, flour, coal, sand, wood shavings, dried food, fertilizer, powder, pigments and plastic granules.As installation places conveyor belts, screw conveyors, silos, funnels are particularly suitable. The inline moisture measurement is also possible in batch processes.
Main Benefits:

● No samples for the laboratory necessary
● Saving of energy costs
● Improvement on the product quality
● Very short amortization time
● High selective sensitiveness
● High measuring speed
● Precision better than 0.1% (depends on product)
● Easy and economic installation
●Fast and simple calibration
●Optional ATEX-Version for zone 20 and zone 0

At the measuring the relative permittivity and the high-frequency recession of the solid is measured in the high-frequency range.
The measurement procedure makes a short and simple calibration as well as a high precision better than 0.1% possible. The measuring probe transmits the data digitally. This makes the measurement assignment disturbance insensitive and allows a distance of the sensor to the end judging unity up to 1000m.The system supervising itself has an integrated data logger besides an automatic compensation of temperature and ageing drift, digital and alarm exits. On the LC display are represented the measurements analogously and digitally.A simple control and parameter setting of all functions is carried out via soft keys. For product or process changes different product parameters can be stored.

Inline moisture meter mounted on the screw feeder for moisture measurement
德国MuTec在线固体水分仪螺旋给料机上的应用
The Inline moisture sensor mounted on the screw feeder works very good, because the measured material is continuously and consistent forwarded on the sensor by spiral blade,  the sensor must be installed under the screw conveyor.

The advantage of Humy3000 installed in the screw conveyor
1. Compared to other installation position, the measurement is best, flow state is relatively stable,the measured data is more representative;
2. Moisture and temperature can be measured at the same time, so that man can control material drying or humidifying;
3. Measurement unaffected by rotation of metal blade, dust and vibration, reliability is extremely high;
4. Material density is needed to keep relatively stable,the best installation position is lower part 20-40 under screw conveyor;
5. Maintenance-free.

HUMY3000 is designed for continuous moisture measurement in der production line. Prerequisite for accurate measurement of bulk materials is to select the correct installation position. We shall ensure that the material fully contact  sensor surface and material thickness as consistent as possible.
