Overview
The Avery Weigh-Tronix WI-127 is a rugged digital weight indicator purpose-built for demanding industrial weighing applications. This control unit provides real-time weight data with high stability and accuracy, making it ideal for truck scales, floor scales, material batching systems, and conveyor weighing operations. The WI-127 combines a bright LED display with sophisticated signal conditioning and filtering to deliver reliable readings even in harsh, vibration-prone environments.
Key Features
- 8-digit LED display (0.8″ high) with seven-segment format for clear visibility from a distance
- Harmonizer filtering system — actively corrects for environmental noise and vibration commonly found on truck scales and in factories
- Multi-sensor support — accommodates up to twelve 350-ohm load cell sensors for flexible scale configurations
- Programmable controls — twenty front panel keys for metrological functions, numeric entry, and configuration
- Dual voltage operation — runs on 115/230 V AC, 50/60 Hz with low power consumption (0.25 A)
- Fourteen status annunciators — clearly identify unit of measure and display state
- High-speed analog conversion — 60 samples per second for dynamic weighing applications
- Multi-point calibration — supports up to five calibration points for precise standardization
