AND Micro balance AD-4531B

Description

• The AND AD-4531B is a precision digital weighing controller built for high-accuracy, single-point measurement using strain gauge sensors.

• Designed for integration into industrial weighing systems, materials testing equipment, or precision monitoring setups.

• Combines robust electronics, versatile calibration options, and fine signal resolution in a compact, user-friendly format.

• Features Digital Span Calibration – enables non-load calibration, eliminating the need for test weights during setup, ideal for field installations or large-scale systems.

• High resolution display – displays values up to ±999,999 with 9.2 mm high red 7-segment LED digits, plus five status indicators.

• High accuracy and linearity – linearity of ±0.005% F.S. (within ±1 digit) and guaranteed input sensitivity of 0.15 µV/d.

• Wide input range – supports span and zero adjustment from –35 to +35 mV (±7 mV/V), compatible with various sensor outputs.

• Fast A/D conversion rate – samples at 100 times/second for responsive measurements in dynamic conditions.

• Temperature stability – zero drift ±0.1 µV/°C (typ.) and span drift ±8 ppm/°C (typ.) for accurate operation over wide temperature ranges.

• Sensor excitation power – supplies 5 V excitation for up to 3 × 350 Ω sensors or 1 × 120 Ω sensor.
