GENERAL INFORMATION

PD-20 S, which takes up very little space in the panel with its compact design; offers an excellent performance for high-speed filling and packaging machines with its 100Hz sampling speed and 1 in 100,000 sensitivity.

Highlighted Smart Technologies:

Advanced Vibration Filter: Thanks to special anti-vibration filters, it provides a stable and accurate measurement by filtering ground vibrations created by motors and moving mechanisms.

Full Electrical Isolation: Device power supply, loadcell input, RS-485 ModBus line, digital inputs, and all of the analog/transistor outputs are isolated independently from each other. In this way, it is not affected by electromagnetic noises (parasitics) in industrial environments.

Effortless Electronic Calibration: In huge tanks or silos where it is difficult to physically use heavy test loads (dead weight), you can calibrate the system within seconds just by entering parametric values (according to the mV/V value).

Multiple Loadcell Support: A single PD-20 S unit; can directly supply and read 4 pieces of 350 Ohm or 8 pieces of 700 Ohm load cells.

ADVANTAGES AND USAGE AREAS

High-Speed Packaging and Filling: Thanks to its advanced filters, it produces stable weighing data within milliseconds.

Easy Integration: Direct digital data transfer to PLC or SCADA systems via ModBus.

Tension Control: Precisely monitoring material tension in paper, plastic film, or textile lines.

Application Areas:

  • Tank, silo, and bunker weighing automations.
  • Overload safety systems.
  • Automatic dosing and batching plants.
  • Tensile-tear testing devices.

The PD-20 E Digital Load Cell Signal Converter (Transmitter) measures sensitive mV-level signals from load cells with high accuracy, processes them, and converts them into weight data. The acquired weight information can be transmitted to PLC, SCADA, and other industrial automation systems digitally via Modbus TCP/IP (Ethernet) or through 0-10 V / 4-20 mA analog outputs. Its high-speed sampling rate, fast response time, and advanced digital filtering algorithms minimize the effects of vibration, mechanical oscillation, and process-induced noise on the measurement. By filtering noisy or unstable signals more effectively, it ensures that weight values are read in a more stable, accurate, and reliable manner. Thanks to its < 10 ms Modbus TCP/IP communication response time and high communication stability, the PD-20 E provides high-performance process communication in applications requiring rapid data transfer, such as dosing, filling, checkweighing, and dynamic weighing.
