AND Micro balance AD-4532B

Description

• The AND AD-4532B is a high-speed, multifunctional digital weighing controller designed for use with strain gauge sensors in applications demanding extremely precise measurements, programmable logic control, and fast response.

• Sampling rate of 2000 times per second with dual tricolor LED displays, advanced comparator, hold, and analog output functions.

• Ideal for force measurement, dynamic weighing, tension control, and high-precision industrial automation.

• Digital span calibration allows setup without actual test weights, reducing installation time and complexity.

• Modbus-RTU compatibility enables seamless connectivity with PLCs, HMIs, and SCADA systems.

• Wide sensor compatibility – works with strain gauge sensors (output resistance ≤10kΩ):

  • 5V excitation: up to 4 × 350Ω sensors

  • 2.5V excitation: up to 2 × 120Ω or 8 × 350Ω sensors

• Flexible calibration options – digital span calibration (no test load required) or standard calibration using actual weights.

• Advanced display system:

  • Main display: 6-digit 7-segment tricolor LED (14mm)

  • Limit display: dual 5-digit green LEDs (9mm)

  • Status indicators: 15 function icons

  • Keypad: 6 tactile function keys

• Hold functions – Sample Hold, Peak Hold, Bottom Hold, and Bipolar Hold for varied measurement applications.

• Comparator output – 5-level comparator control (HI/OK/LO) with MOSFET relay output rated for industrial use.

• Analog output – ±10V scalable analog output (1/10,000 resolution, 100 ppm/°C temp. coeff.).

• Zero compensation & key lock – operator-level security and automatic zeroing for system reliability.

• Wide adjustment ranges:

  • Span: ±0.25 to ±3 mV/V

  • Zero: ±50% of span-adjusted value

• Exceptional sensitivity:

  • Minimum guaranteed input: 0.6 µV/d

  • Minimum guaranteed display: 0.12 µV/d

• Durable & compact housing – standard 96 × 96 mm panel size with cut-out dimensions 92 × 92 mm.

• Power supply – AC 85–250V, 50/60 Hz (~20 VA).
