SUNNY HENGPING JA Series Precision Industrial Bench Scale

Overview

The SUNNY HENGPING JA Series Precision Industrial Bench Scale is an entry-level yet rigorously engineered precision balance designed for quality control, production line verification, and laboratory-grade material handling in industrial environments. Based on electromagnetic force compensation (EMFC) transduction technology, the JA series delivers stable, drift-resistant weighing performance under variable ambient conditions—critical for batch consistency in manufacturing, raw material intake inspection, and packaging weight validation. Its robust mechanical architecture integrates a high-stiffness stainless steel weighing pan (336 × 242 mm), reinforced load cell housing, and vibration-damping base structure to minimize environmental interference. Unlike analytical balances optimized for sub-milligram resolution, the JA series prioritizes operational durability, rapid stabilization (<2 s), and long-term calibration stability—making it suitable for daily use in workshops, warehouses, and ISO-certified production floors where reproducibility at the 0.1 g level is required across thousands of cycles.

Key Features

• Stainless steel weighing pan (336 × 242 mm) with corrosion-resistant finish and easy-clean geometry
• Electromagnetic force compensation (EMFC) sensor system ensuring high linearity and minimal hysteresis
• RS232 serial interface compliant with standard ASCII protocol for direct integration into MES, ERP, or LIMS systems
• Full-range universal power adapter (100–240 V AC, 50/60 Hz), eliminating voltage conversion requirements in global deployments
• Multi-function operation modes: standard weighing, piece counting (with automatic average piece weight calculation), percentage weighing (relative to reference mass), and zero-tracking
• External calibration capability using certified Class M2 or better weights—fully traceable to national metrology institutes
• Front-panel keypad with tactile feedback and backlit LCD display (character height ≥ 8 mm) for legibility under low-light factory conditions

Sample Compatibility & Compliance

The JA series accommodates heterogeneous sample types—including powders, granules, pre-packaged components, and small assemblies—within its 5000 g maximum capacity and 336 × 242 mm pan area. The pan’s low-profile geometry minimizes wind draft effects and supports container tare operations without instability. From a regulatory standpoint, the instrument conforms to OIML R76-1 (2006) for non-automatic weighing instruments, meets EN 45501:2015 structural and metrological requirements, and supports GLP/GMP documentation workflows via timestamped RS232 data export. While not intrinsically rated for hazardous areas, its IP42-rated enclosure provides protection against dust ingress and vertically falling water droplets—suitable for controlled indoor industrial settings.

Software & Data Management

Data output follows NIST-traceable ASCII format via RS232 at 9600 baud, 8N1 configuration. Each transmitted record includes timestamp (when enabled externally), gross/net/tare values, unit identifier (g), and operation mode flag. No proprietary software is bundled; instead, the scale is compatible with industry-standard data acquisition platforms—including LabVIEW™ drivers, Excel-based macros (via ActiveX), and custom SCADA integrations. Audit trail generation requires external logging; however, the device supports user-defined printout formats (e.g., label templates with batch ID, operator code, and QC pass/fail flag) when connected to compatible thermal or dot-matrix printers.

Applications

• Raw material receipt inspection in pharmaceutical excipient and nutraceutical manufacturing
• Component counting and kitting verification in electronics assembly lines
• Fill-weight validation for semi-solid cosmetics and food products prior to sealing
• Inventory reconciliation and warehouse cycle counting with documented traceability
• Educational laboratories requiring durable, serviceable precision instrumentation for metrology training
• Calibration lab support roles—e.g., as a secondary standard for verifying lower-tier platform scales

FAQ

What calibration weights are required for routine verification?
Class M2 weights (certified to ISO 9001 or ISO/IEC 17025) with nominal values covering 5%, 50%, and 100% of full scale (e.g., 250 g, 2500 g, 5000 g) are recommended for intermediate checks between formal calibrations.
Is internal calibration available?
No—the JA series relies exclusively on external calibration to maintain metrological transparency and facilitate third-party audit readiness.
Can the scale be mounted on a vibration-isolated table?
Yes; the unit’s low center of gravity and rigid base allow secure mounting using M4 threaded inserts (optional accessory kit). Vibration isolation is advised when installed near CNC machinery or compressors.
Does the RS232 interface support bi-directional communication?
No—it operates in transmit-only mode. Commands such as tare or unit change must be executed locally via front-panel controls.
What is the expected service life under continuous industrial use?
With scheduled maintenance (cleaning, leveling check, and annual sensor verification), the design lifetime exceeds 8 years at two shifts per day, based on accelerated life testing per IEC 60068-2 standards.
