Micro balance AND AD-4404

Micro balance AND AD-4404

The Micro balance AND AD-4404 is a multi-functional, high-speed digital weight indicator designed to meet the precision control demands of modern industrial environments, especially where fast, repeatable, and intelligent weighing is required. With a sampling speed of 100 times per second, a resolution up to 1 million A/D counts, and a comprehensive range of automated functions, this indicator is ideally suited for checkweighing, batching, filling, quality control, and process automation.

It features a bright 13mm fluorescent display, comparator lights and buzzer, programmable weighing triggers, and memory for up to 100 product codes—all built into a heavy-duty, sealed housing for reliable use in industrial settings.

Key Features

• Ultra-Fast Sampling Rate – 100 samples/second ensures real-time response in fast-paced production lines.

• High Display Resolution – Up to 16,000 counts on screen and 1,000,000 A/D internal resolution for superior accuracy.

• Comparator Output with Visual & Audio Alerts – Hi/OK/Lo or HiHi/Hi/Lo/LoLo modes with LED indicators and buzzer for quick judgment at a glance.

• New Foreign Material Detection Input – Enhances inspection capability by detecting irregularities alongside weight measurements.

• Bar Graph Display – Visual representation of how weight falls within target range; intuitive feedback for operators.

• Built-in Timer Control – Can activate weighing via an external photoelectric switch or weight-based trigger, ideal for transparent or fast-moving items.

• Multi-Data Display at the Touch of a Button – Displays weight, accepted piece count, accumulated totals, product name, and standard deviation instantly.

• Memory for 100 Item Codes – Stores target, upper/lower limit, and tare values for each code, simplifying product changeover.

• Flexible Target Configuration – Supports 5-digit target weights and 4-digit limit values, with adjustable decimal placement and front-panel programmability.

• Sealed Front Keys – Prevent dust and moisture ingress, ideal for harsh environments.

• RS-485 and Current Loop Output – Built-in communication for data logging and system integration.

• Full Digital Calibration – Simplifies zero and span calibration without manual adjustments.

• 11 Digital Inputs & 11 Open Collector Outputs – Standard I/O for full system control; optional dry contact relays available.

• Auto-Zero Maintenance – Adjustable zero tracking for long-term stability.

• Front Panel Lockout – Prevents unauthorized adjustments by operators.

• RFI/EMI Shielded Construction – Protects against signal interference in electrically noisy environments.

• Programmable Gravity Compensation – Ensures location-based accuracy for global operations.

• Selectable Units – Supports g, kg, t, lb, and a blank option.

Applications

• High-Speed Checkweighing – Identify pass/fail products in real time with visual and audible alerts.

• Batching & Mixing Control – Store up to 100 batch profiles with programmable targets and tolerances.

• Filling & Dispensing Systems – Use timer and sensor triggers for weight-activated filling of containers or packages.

• Inspection Systems – Use foreign material detection input alongside weight checking for quality assurance.

• Process Automation – Integrate with PLCs and conveyors using built-in I/O and communication protocols.
