Page 3: Principle Of Operation
CAUTION: When handling this instrument, take care to exercise industry standard practices for electro- static management. Sensitive electronic components may be damaged by electrical discharge that is far below the limits of human perception. Such voltage occurs even when you touch a component or electrical connections of a component and are not electrostatically discharged. -
Page 4: Description Of Sensor
· 20-bit measured value acquisition and measured value process- ing in the sensor · Automatic temperature compensation according to stored table · High degree of functional reliability combined with self-monitor- ing function · Low power input (≤ 350 mW) · Digital transmission of measured values immune to interference via RS-485 interface ·... -
Page 5: Mounting And Assembly
4.0 MOUNTING AND ASSEMBLY Sensor location The HumiCore™ 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. -
Page 6: Indirect Installation
4.2 Indirect installation Indirect installation of the sensor is necessary if the wall thickness is 0.39” (10 mm) or more or the wall is curved. In such cases use of a welded flange is recommended. (See Figure 6) bulk material weld M6 - threaded bolt Figure 6... -
Page 7: Mounting At Conveyor Belt
4.4 Mounting at a conveyor belt When installing the moisture sensor on a conveyor belt, an optional sled or ship may need to be incorpo- rated into the conveyor belt system. (See Figure 8) A sled would be used in a situation where the material flow is more even and the sensor would slide over the material. -

Page 9: Calibration
6.0 C ALIBRATION 6.1 Overview The importance of accurate calibration cannot be overstated. The data collected during the calibration process will determine the final operating accuracy of the instrument. Calibration consists of observing a properly installed HumiCore™ Pro operating under actual process conditions. -
Page 10: Programming And Calibration Hardware Set Up
6.2 Programming and Calibration Hardware Set Up The HumiCore™ Pro is set up, and calibration setting established, by use of a PC and the HumiCore Configuration Program.

7.0 HUMICORE™ PRO CONFIGURATION PROGRAM SCREENS Products The main screen ‘Products’ consists of two subcategories: product-settings and calibration. The first step is to select the respective product. The system offers the option of saving and retrieving 24 products. The respective products are referenced via the following pull-down button. Figure 25 In the first field ‘Product Name’... - Page 17 IMPORTANT: After every setting in the respective screen the data must be transferred to the HumiCore™ Pro system using the ‘Program parameters’ button! Otherwise there is a risk of losing the settings (see ‘Program parameters’ in Section 6.3)! If all product settings are done, you are able to start the calibration. A good and exact calibration is absolutely necessary to achieve high measuring accuracy.
- Page 18 The 1st calibration point: After specifying the number of calibration points and/or the calibration time, you can start the actual calibra- tion. To do so, click on the button ‘Calibration capture’ at the ‘1st calibration point’, then the window below (Figure 30) opens and calibration begins.

Page 19: Digital Inputs
Digital Inputs Figure 32 The HumiCore™ Pro transmitter has two digital inputs. Different functions can be performed when the inputs are connected and activated. The digital inputs have to be connected to a control signal of 0 volts or 10 to 24 volts DC. The following functions are available: Measurement STOP: This stops the measurement and freezes the value last indicated. -
Page 20: Analog Output
Analog Output Figure 33 The (measuring) range and the mA values (or V) of the analog outputs are defined in the main screen ‘Ana- log outputs’. “Current” or “voltage” can be selected as the output signal via a pull-down menu. One analog output is available. - Page 21 MIN and MAX limits as well as the output signal in the event of a malfunction can be freely defined. The analog output for moisture offers an additional function for batch processes. In this case you can select via the pull-down button whether the mean value or the current value should be used in the calculation. IMPORTANT: After every setting in the respective screen the data must be transferred to the HumiCore™...

Page 22: Max-Alarm
MAX-Alarm Figure 35 In the first field the ‘alarm value’ is freely definable. The ‘delay’ describes the desired delay the system needs to complete the switching process. This is in- tended to avoid changeable “switching” of the switch. Example: In Figure 35 the MAX alarm is set to 85% and the alarm delay to 1 second. If the respective value drops below the alarm value, switching of the alarm does not take place until after another control value after one second. -
