  • Page 5: Functional Description

    TRIME-GW Line consists of the measurement transformer TRIME-GW casing and the 1-rod-probe head. An integrated TRIME TDR measuring transducer of IMKO´s SONO-series is installed into the TRIME-GW Line casing. A high frequency 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.

  • Page 6: Mode Of Operation

    Mode of Operation Measurement value collection with pre-check, average value and filtering TRIME-GW Line measures internally at a very high rate of measurements per second and issues the resulting measurement value at a cycle time of up to 200 milliseconds at the analogue output. Within this cycle time of 200 milliseconds a probe-internal pre-check of the moisture values is included.

  • Page 7: The Serial Rs485 And Imp-Bus Interface

    The initial default setting of the serial interface is pre-set for the IMP-Bus. To operate with the RS485 it is necessary to switch and activate the RS485 interface with help of the modul SM-USB. The transmission protocol of TRIME-GW Line can be requested via “Contact us” on www.imko.de. The IMP-Bus as a user friendly network system With external power supply on site for the SONO probes, a simple 2-wire cable can be used for the networking.

    Connectivity to TRIME-GW Line Compatible to SONO probes How to configure SONO-probes to appropriate operating and calibration parameters? TRIME-GW Line is initially adjusted for the application for grain drying with the calibration curve Cal14, operation mode CF and 3 seconds average time. The analogue outputs are adjusted to 4..20mA. With this pre-adjustment TRIME-GW Line can be installed direct in the heating zone, without further adjustments.

    B: Configuration via SM-USB The SONO-probe is connected via the SM-USB and the RS485-interface to a PC. With help of the software tool SONO-CONFIG it is possible to configurate SONO-probes to an appropriate operating mode. The operating mode depends on the application like the moisture measurement under a silo flap, inside a mixer or on a conveyor belt. The SONO-probe can be adapted to the appropriate operating mode like cyclic measurement, averaging, filtering, cumulating and other powerful operating parameters.

    Initial operation and adjustments Adjustment Guidelines for Moisture Measurements Please read the detailed description first and subsequently use these guidelines as a checklist for adjustments. 1. Extract samples from as close as possible to the probe. 2. Select calibration curve with help of SONO-VIEW or via the module SM-USB. Note: TRIME-GW Line is initially adjusted for the application for grain with the calibration curve Cal2.

  • Page 20: Selection Of The Individual Calibration Curves

    In the menu "Calibration" and the window "Material Property Calibration" the calibration curves CAL1 to Cal15 which are stored in the SONO probe are loaded and displayed on the screen (takes max. 1 minute). With the mouse pointer individual calibration curves can be activated and tested with the SONO-probe by activating the button "Set Active Calib".

  • Page 23 Mode CS: (Cyclic-Successive) For very short measuring processes (e.g. 5…20 seconds) without floating average, with internal up to 100 measurements per second and a cycle time of around 200 milliseconds at the analogue output. Measurement mode CS can also be used for getting raw data from the TRIME-GW Line without averaging and filtering.

    Parameters in the Measurement Function Mode CA, CF, CC, CH and CK No-Material-Delay CA/CF/CK: inactive (period time) CC/CH: The accumulation stopps if the moisture value is below the Moisture Standard Setting: 10s Threshold. The accumulation pauses for the period of the setted delay time Setting Range: 1…100s and will be frozen if the moisture level is below the threshold value.

  • Page 25: Filtering At Material Gaps In Mode Ca And Cf

    For applications with non-continuous material flow, there is the option to optimise the control of the measurement process via the adjustable filter values Filter-Lower-Limit, Filter-Upper-Limit and the time constant No-Material- Keep-Time. The continual/floating averaging can be set with the parameter Average-Time. Average Time in the measurement mode CA and CF TRIME-GW Line 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 following parameter setting in mode CA fits a high pass filtering for bridging material gaps. 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.
  • Page 27 Following possible parameter settings in mode CC inside the TRIME-GW Line can be set: Parameter in mode CC Function Moisture Threshold The accumulation of moisture values starts above the „Moisture Threshold“ (in %-moisture) and the analogue signal is output. The accumulation pauses if the moisture level is below the threshold value.

  • Page 28: Serial Connection To The Sm-Usb Module

    The SM-USB provides the ability to connect a SONO probe either to the standard RS485 interface or to the IMP- Bus from IMKO. In fact that the IMP-Bus is more robust and enables the download of a new firmware to the SONO probe, the SONO probes are preset to the IMP-Bus.

    Quick Guide for the Commissioning Software SONO-CONFIG With SONO-CONFIG it is possible to make process-related adjustments of individual parameters of the SONO pro- be. Furthermore, the measurement values of the SONO probe can be read from the probe via the serial interface and displayed on the screen.

  • Page 31: Configuration Of Serial Sono-Interface

    Configuration of serial SONO-interface The serial interface inside the SONO probe can be selec- ted to IMP-Bus or RS485. Due to very robust behavior it is recommended to select the IMP-Bus. Set analogue outputs of the SONO probe In the menu "Config" and the window "Analog Output" the two analogue outputs of the SONO probe can be con- figured (see Chapter “Analogue outputs”).
