Continuous inline moisture measurement
Application
Moisture in solids is an important parameter that in-
fluences the quality of a product and the economic
efficiency of production. Nevertheless, in many
companies, product moisture is only determined in
the laboratory. These random sample measure-
ments are time-consuming and the results are only
available with a delay.
The HUMY 301 inline moisture measurement sys-
tem is the better alternative. Its real-time measure-
ment enables an immediate response to moisture
changes in the process. The measurement results
can be used to control a dryer or automatic humidi-
fication or to continuously monitor the process.

Page 15: Intended Use
06/24 Intended Use The moisture measuring system consists of the HUMY 301 control and evaluation unit in a top- hat rail housing and the FMS 410 moisture sensor. The inline measuring system for process monitoring guarantees trouble-free measurement of the internal product moisture of solids and emulsions. -
Page 16: Setup Oft He Sensor
06/24 Setup of the Sensor Built into a solid cylindrical stainless steel housing, the probe is largely insensitive to external influences. A special internal encapsulation protects the entire electronics from the ingress of moisture and increases resistance to alkalis, acids and solvents. The electrical connection is made via a fixed cable connection in the probe and guarantees IP67 tightness thanks to the high-quality PG screw connection. -
Page 17: Assembly
06/24 Assembly Mounting of transmitter The ME-MAX housing can be combined with a 5-pole TBUS connector/ DIN rail connector. The RS485 interface and the supply voltage can be conveniently wired through via the TBUS con- nector snapped into the top-hat rail. The TBUS connection is set up automatically in the grid of the devices involved. -
Page 18: Mounting Of Sensor
06/24 Mounting of sensor The HUMY 301 is designed for continuous moisture measurement in the production flow. The prerequisite for correct moisture measurement in bulk materials is always the correct choice of installation location for the moisture probe. With bulk material chutes or conveyor belts, care must also be taken to ensure that the measured material is guided over the probe with as uniform a layer height as possible. -

06/24 9.2.6 Free-fall tube Installation in a free-fall application: 9.2.7 Installation with a separating layer Indirect installation of the HUMY probe is necessary if the wall thickness is 10 mm or more or if the wall is curved. In such cases, the use of a weld-on flange is recommended. 9.2.6 Mounting with a protective cap The measuring window must be in direct contact with the material to be measured. -
Page 21: Outdoor Installation
06/24 The recommended arrangement for chain conveyors or for measuring media with a temperature of over 80°C up to a maximum of 120°C is the use of a separating layer of 5 to 15 mm. The permissible thickness depends on the material to be measured and the residual water content. The measuring surface of the moisture sensor must always have mechanical contact with the separating layer. -

06/24 The cable shield is connected to the earthing contact in the probe. If the cable shield is also earthed at the other end of the cable and there is a significant po- tential difference between the two earthing points, a considerable equalizing current flow across the cable shield can be the result. -

Page 44: Calibration
06/24 15 Calibration A good and precise calibration is essential to achieve a high level of measurement accuracy. The number of calibration points must be determined first. In most cases, 2 calibration points are sufficient, in which case linear behavior is assumed. A maximum of 5 calibration points can be selected. -
Page 45: Number Of Calibration Points
06/24 Example: The expected moisture range is between 10 and 15%. Recommended setting for scaling the analog output: 5% (range start 4mA) - 20% (range end 20mA). 15.2 Number of calibration points A calibration curve can be created with a minimum of 2 to a maximum of 5 calibration points, depending on the accuracy requirement. -
Page 46: Determining The Optimum Filter Value
06/24 15.4 Determining the optimum filter value The software offers various filter algorithms for smoothing the digital output signal. A combina- tion of median filter for eliminating outliers and Pt1 average filter for smoothing the signal is recommended. The filter values can be changed in the online view and the effect on the signal can be tested directly. - Page 47 06/24 Raw signal with activated median filter over 7 measured values: Raw signal with activated median filter over 7 measured values and mean value filter PT1 (filter length 5s): Mütec Instruments - Your safe choice At the Kämpen 26 Phone: +49 4185/8083-0 Mail: muetec@muetec.de D-21220 Seevetal-Ramelsloh...

Page 48: Graphical Determination Of A Calibration Point
06/24 A large time constant of the mean value filter leads to optimum smoothing of the signal, but abruptly changing signal curves are registered with a time offset. A combination of median fil- ter and subsequent smoothing using a PT1 mean value filter is therefore recommended. For static measurements, a median filter value of 3 measured values and a mean value of 2s is usually sufficient to smooth out the noise of the digital value. -
Page 49: Offline Calibration
06/24 15.6 Offline calibration Similar to the graphical determination of a calibration point, calibration can also be carried out using historical data. This means that a laboratory sample can be taken and analyzed at any time during the process, which is then later assigned to a historical raw value. Example: A laboratory sample was analyzed on 15.05.2024 at 15:05. -
