Overview of the Cedar WDI Series Torque Tester

Inheriting extensive experience in torque measuring equipment manufacturing from Sugisaki Meter (Japan), the Cedar WDI series (including WDI-10HR, WDI-100HR, and WDI-250) is an optimal quality management solution for precision mechanical and electronic assembly lines. The device supports accurate torque testing and calibration for a wide variety of tools such as electric screwdrivers, pneumatic screwdrivers, manual torque screwdrivers, and torque wrenches.

The WDI series is intelligently designed to enhance data management and automation capabilities. Through standard communication ports (USB and RS232C), the device can easily export measurement data to a computer (PC) or communicate directly with automated control systems such as PLCs. This helps factories strictly control Standard Operating Procedures (SOP), minimize errors, and improve assembly line efficiency.

Key Features of the Cedar WDI Series

✓
Intuitive Color LCD Display: The vivid color display allows technicians to easily view parameters, confirm measurement values, and evaluate pass/fail (OK/NG) results quickly and accurately.
✓
Flexible Data Management & Export: Integrated USB and RS232C ports enable seamless data transmission to a PC. Supports efficient storage and management of inspection information, optimizing quality reporting workflows.
✓
Large Data Storage: Internal memory capable of storing up to 800 measurement values, ensuring data security without risk of loss during shop-floor inspection processes.
✓
Diverse Measurement Modes: Supports flexible bi-directional (CW/CCW) measurement with multiple specialized modes such as Peak Hold (retains peak value), Peak Down, and Real-time (real-time measurement), meeting various inspection requirements.
✓
External System Control: Intelligent I/O signal input/output capability allows automatic startup from a PLC or triggering of external equipment when preset tolerance levels are reached.
✓
Portable & Convenient: Powered by an internal rechargeable Ni-MH battery and equipped with an Auto Power-off function (automatically turns off after 10 minutes of inactivity), saving battery life and allowing easy movement between workstations.

Practical Industrial Applications

The Cedar WDI series torque tester is an essential measuring instrument for factory Maintenance and Quality Assurance/Quality Control (QA/QC) departments:

Periodically check and calibrate standard torque for electric screwdrivers and pneumatic impact wrenches before each work shift.
Ensures torque consistency across the entire production line, eliminating product defects caused by under-tightening (loose screws) or over-tightening (stripped threads).
Systematically collects actual torque data for statistical analysis and continuous improvement of the assembly process.
