The BPT-31 is designed for measuring, processing, and displaying signals from strain gauge load cells (scales), as well as for generating a standardized analog or digital output signal proportional to the measured weight.

⚙️ Functional Capabilities:

📏 Weight Measurement:

  • Accepts input from a strain gauge load cell (2–4 mV/V)
  • Converts input to a digital value representing the measured weight
  • Supports calibration and correction of the load cell input signal
  • Includes digital filtering to reduce fluctuations caused by vibration, load shifts, or motion

⚖️ Scaling and Taring:

  • Manual or automatic zeroing
  • Tare function for deducting container or packaging weight
  • Input signal scaling (calibration) and range setting

🔄 Output Signal Generation:

  • Analog output: 0–10 V, 4–20 mA, or other standardized signals for PLCs/controllers

📟 Display:

  • 6-digit digital LED display
  • Additional status indicators for operation mode and signal alarms

🔗 System Integration:

  • Digital interfaces: RS-485 (Modbus RTU), USB
  • Full integration with SCADA/HMI via Modbus RTU
  • Configuration of setpoints, scaling, filtering via keypad or PC software
Inputs:
  • quantity: 1
