High Precision Electronic Weighing Indicator For Automatic Filling Machine

Product Specification

TFT-Touch Ration Filling Controller, Liquid Filling Machine Controller/Indicator

Main Features:

1. Suitable for Liquid/Gas/Powder Ration Fillingweigher.

2. Optional application modes: Fill on Drum’s Top / Fill on Drum’s Bottom / Step-fill from Bottom.

3. EMC design with high anti-jamming capability, suitable for industrial environment.

4. Cortex-A8 CPU with 600MHz Clock, 128M RAM and 128M Flash.

5. 7”/10.2” Ultralight and ultrathin TFT touch screen with embedded weighing/control module.

6. Loadcell Interface

    Max. Connection Quantity: 16 Loadcells (350Ω).

    24-bit High-precision and high-speed ∑-A/D conversion module with 1/1,000,000 internal resolution and sampling frequency 800Hz.

    Special anti-vibration digital filtering algorithm for ensuring the weighing stability and accuracy when there is strong vibration on the load         receptor, and the rapid response capability when the weight signal changes.

7.I/O Interface

   9 Definable normally open switch inputs [DI] and 18 definable normally open transistor switch outputs [DO].

   Optional ‘High-speed/Medium-speed/Low-speed Fill’ DOs for Filling control. Optional Low-speed Filling Modes: Continuous Filling Mode and  Inching Filling Mode.

    2 Definable analog signal AO[0~10V] for weight signal output or ‘High-speed/Medium-speed /Low-speed Fill’ control.

8. Digital Communication Interface

    COM1[RS232]&COM2[RS485] for connecting Host IPC/PLC and LED Remote Display.

    COM[RS232] for connecting RS232 Serial Printer.

    USB1 for connecting USB mouse, downloading HMI software from U-disk and copying data to U-disk.

9. Software Function

    Manual Screen-locking/Screen-unlocking, Auto Screen-locking, Digital Setting&Calibration and I/O Testing functions available.

    Initial Zero Adjustment after Power-on, Auto Zero Tracking, Zero Fine Adjustment and Zero Calibration functions available.

     Load Calibration function available.

     10 Recipes for filling control.

     Optional ‘Fall Value Auto Correction’ function.

     Optional ‘Auto Pause for Deviation Alarm’ and ‘Auto Re-fill’ functions.

     ‘Target Batch [Count/Weight] Finished’ alarm function available.

     The Batch Records can be printed automatically.

      Historical Batch Records, Totalizing Reports and Recipes can be queried and printed.

     With the multitasking mode, the weighing&control process will not be interrupted by parameter setting and the other operations.
