Micro balance AND AD-4212D-302

AD-4212D-302 Smart Precision Weighing Sensor

The AD-4212D-302 from A&D is a high-precision, smart weighing sensor designed for automated systems, laboratories, and precision manufacturing environments where microgram-level accuracy and environmental resilience are critical. With 1 µg minimum readability, advanced overload protection, and a compact footprint, this model delivers exceptional performance and versatility in real-time production and analytical applications.

Key Features:

• Smart Dual-Range Functionality:
  Automatically switches between two ranges:

  • Precision range (up to 5.1g) with 1 µg resolution

  • Standard range (up to full capacity) activated when exceeding 5.1g
    The system returns to precision mode upon RE-ZERO (tare), streamlining transitions between fine and larger samples.

• Built-In A/D Converter for Direct PC or PLC Communication:
  Allows for real-time data capture and device control via RS-232C using WinCT-AD4212D software—ideal for smart manufacturing and automation platforms.

• IP65 Water and Dust Resistance (with protective cap installed):
  Ensures reliable operation in harsh industrial environments, allowing easy cleaning and robust field use.

• Microgram-Level Performance:

  • Minimum Readability: 1 µg

  • Repeatability: 0.002 mg (for 1g mass using auto loader)*²

  • Linearity: ±0.002g (over 10g)*³
    Supports the most demanding precision tasks with verified performance metrics.

• Adjustable Response Characteristics:
  Adaptable to cope with environmental disturbances such as drafts, vibration, or airflow—ideal for both open-lab and enclosed systems.

• Advanced Mechanical Protection:
  Features built-in overload safeguards against vertical and transverse forces caused by actuator malfunctions or improper handling.

• Flexible Installation and Integration:

  • Underhook for magnetic material weighing or density measurements

  • Customizable pan/receptacle design support

  • Mountable base with optional removal of leveling feet for fixed installation

• Built-In Calibration Weight:
  Enables one-touch internal sensitivity adjustment, ensuring consistent accuracy with minimal user effort.

• Compact Breeze Break Included:
  Reduces the effect of environmental airflow for added stability in sensitive measurements.

• Expandable with A&D Peripherals:
  Compatible with a wide range of A&D external devices, increasing adaptability and functionality in custom setups.
