    TDR pulse (1GHz), passes along wave guides and generates an electro-magnetic field around these guides and herewith also in the material surrounding the probe. Using a new patented measuring method, IMKO has achieved to measure the transit time of this pulse with a resolution of 1 picosecond (1x10 ), consequently determine the moisture and the conductivity of the measured material.

  • Page 5: Mode Of Operation

    5/44 1.2. Mode of Operation 1.2.1. Measurement value collection with pre-check, average value and filtering SONO probes measure internally at very high cycle rates of 10 kHz and update the measurement value at a cycle time of 250 milliseconds at the analogue output. In these 250 milliseconds a probe- internal pre-check of the moisture values is already carried out, i.e.

  • Page 6: Analogue Outputs

    Normally this is related with high efforts in laboratory works. SONO probes offer the possibility to set special temperature compensation parameters t0 to t5 for every calibration curve Cal1 of Cal15 (see chapter “Selection of the individual calibration curve”). Please contact IMKO should you need any assistance in this area.

    RS485-Interface. In addition, the SONO-VARIO can be directly connected to the USB port of a PC, in order to adjust individual measuring parameters or conduct calibrations, via the RS485 USB Module which can be provided by IMKO. 1.2.7. Error Reports and Error Messages SONO-VARIO is very fault-tolerant.

    CONFIG. For all activities regarding parameter setting and calibration the probe can be directly connected via the RS485 interface to the PC via a RS485 USB-Module which is available from IMKO.

  • Page 10: Average Time In The Measurement Mode Ca And Cf

    10/44 1.4.1. Average Time in the measurement mode CA and CF SONO-VARIO establishes every 200 milliseconds a new single measurement value which is incorporated into the continual averaging and issues the respective average value in this timing cycle at the analogue output. The averaging time therefore accords to the “memory” of the SONO-VARIO. The longer this time is selected, the more inert is the reaction rate, if differently moist material passes the probe.

  • Page 11: Mode Cc - Automatic Summation Of A Moisture Quantity During One Batch Process

    11/44 The Filter Upper-Limit is here deactivated with a value of 20, the Filter Lower-Limit is set to 2%. With a Lower-Limit Keep-Time of 5 seconds the average value will be frozen for 5 seconds if a single measurement value is below the limit of 2% of the average value. After 5 seconds the average value is deleted and a new average value building starts.
  • Page 12 12/44 How can the mode CC be used, if the SONO probe cannot detect the „moisture threshold“ by itself, e.g. if there is constantly material above the probe over a longer time: In this case, a short interrupt of the probe´s power supply, e.g for about 0.5 seconds with the help of a relay contact of the PLC, can restart the SONO probe at the beginning of the material transport.

    Nonlinear calibrations are possible with polynomials up to 5th grade (coefficients m0...m5). IMKO publish on its website more suitable calibration coefficients for different materials. These calibration coefficients can be entered and stored in the SONO probe by hand (Cal14 and Cal15) with the help of SONO-CONFIG.

SONO-VARIO for measuring Moisture of Sand and Aggregates The TRIME-TDR technology with the radar method offers high reliability for measuring moisture of sand and aggregates, as different grain sizes, unlike other measurement techniques such as microwave technology, do not cause any distortion of the measurement result.

    17/44 1.5.2. SONO-VARIO for measuring Moisture of Expanded Clay and Lightly Sand Concerning the material density, expanded clay and lightly sand differ significantly in comparison to sand and gravel. Therefore a separate calibration for each material is necessary. It is to consider that expanded clay below a moisture level of 12% still can absorb more water, ie here it must be calculated with more addition of water into a mixture.

  • Page 18: Creating A Linear Calibration Curve For A Specific Material

    18/44 1.6. Creating a linear Calibration Curve for a specific Material The calibration curves Cal1 to Cal15 can be easily created or adapted for specific materials with the help of SONO-CONFIG. Therefore, two measurement points need to be identified with the probe. Point P1 at dried material and point P2 at moist material where the points P1 and P2 should be far enough apart to get a best possible calibration curve.

  • Page 19: Nonlinear Calibration Curves

    Therefore it is necessary to calibrate with 4…8 different calibration points. To calculate nonlinear coefficients for polynomials up to 5th grade, an EXCEL software tool from IMKO can be used (on request). It is also possible to use any mathematical program like MATLAB for finding a best possible nonlinear calibration curve with suitable coefficient parameters m0 to m5 which can be entered into the probe with help of SONO-CONFIG.

  • Page 31: Installation Of The Probe

    31/44 3. Installation of the Probe The installation conditions are strongly influenced by the constructional circumstances of the installation facility. The ideal installation location must be established individually. For measuring sand, gravel and grit, the SONO-VARIO should ideally be installed under a silo valve, which has many advantages (see below).

  • Page 32: Further Assembly Instructions

    32/44 3.1. Further Assembly Instructions  With the universal holder, deliverable by Imko, the SONO-VARIO can be placed above a conveyor belt. Particularly with inhomogeneous or loose sand, the material can be constantly condensed, which leads to higher measurement results.

  • Page 33: Assembly Dimensions

    33/44 3.2. Assembly Dimensions SONO-VARIO can either be installed at the base or the side wall of containers. One fact to consider is that the installation into the container base also enables the measurement of smaller material quantities. A mounting flange is available for SONO-VARIO. The flange can both be welded on to the base and the side wall of the container.

  • Page 35: Mounting In Curved Surfaces

    35/44 3.3. Mounting in curved Surfaces In order to prevent the probe head from projecting and interfering with wipers, the centre of the probe head should be flush with the radius of the wall. The ceramic must be laterally aligned to the rotational axis as the gap towards the wipers is smallest in this position.

  • Page 36: Gas- And Waterproofed Installation

    36/44 3.5. Gas- and waterproofed Installation For a pressure-tight installation in a temperature range of -20 ° C to +80 ° C, a flange installation is recommended. The mounting flange can be welded to the container wall. Sealing is possible with a 5.5mm thick O-ring which is fixed with a locking ring.

  • Page 37: Installation In A Conveyor Pipeline

    37/44 3.6. Installation in a conveyor pipeline For a pressure-tight installation of the SONO-VARIO in a conveyor pipeline, it is important that the material flow inside the pipe will not be disturbed. This can be realized with a concavely curved flange which is welded on the pipe, in such a way that the radius of the pipe is only disturbed with the flat ceramic plate of the SONO-VARIO with a width of 32mm and a length of 86mm.

This is how easy it is to exchange the wear-resistant probe head: - Loosen the 4 fastening screws (look for the right sequence of washer and gasket rings).
