Wireless Swing Type Torque Transducer (for Interchangeable-Head Torque Wrench)

(Also known as Wireless Reaction Torque Sensor for Torque Wrenches / Swing-Arm Smart Transducer)

The Wireless Swing Type Torque Transducer for Interchangeable-Head Torque Wrenches is a reaction-based, wireless torque measurement module integrated into the wrench body or handle area.

It accurately measures the applied torque through reaction strain generated during tightening, and transmits data wirelessly to a receiver or torque controller in real time.

Unlike rotary transducers (which measure torque on a rotating shaft), the swing type captures reaction torque — the counterforce acting on the wrench handle when torque is applied — making it ideal for manual, click-type, or electronic torque wrenches equipped with interchangeable heads (open-end, ratchet, flare, or crowfoot).

This innovative design, pioneered by ZIPPTORK, transforms conventional torque wrenches into smart, traceable fastening instruments that comply with Industry 4.0 and IIoT standards.

Working Principle

1. Torque Application:
   When the operator applies torque to tighten a fastener, the wrench head transmits force through the swing-type sensing body.

2. Reaction Detection:
   The internal strain gauge bridge bonded to the swing body measures micro-deformation proportional to the reaction torque.

3. Signal Conversion:
   An embedded circuit board with A/D conversion filters the signal.

4. Wireless Transmission:
   The processed data is transmitted wirelessly (via RF, Bluetooth, or Zigbee) to a receiver or controller.

5. Data Output & Integration:
   Torque, angle, and time data are displayed on a digital controller or wrench display or transferred to an MES / SPC / cloud system for traceability and quality control.

Key Features

• Fully Wireless Operation:
  No cable or external signal line — ideal for manual assembly and ergonomic use.

• Compact Swing-Body Design:
  Embedded near the wrench handle or head interface, it does not affect tool balance or calibration.

• Interchangeable Head Compatibility:
  This tool works with open-end, ratchet, flare, or crowfoot heads through a standardized drive interface.

• High Accuracy:
  ±1%–2% of full-scale torque, with built-in digital calibration compensation.

• Shock & Vibration Resistance:
  Special swing-arm mechanical design isolates the operator’s hand load and external impacts.

• Real-Time Wireless Data Transmission:
  Torque and angle data are sent to the controller or data logger via RF or BLE module.

• Battery or Inductive Power:
  Long battery life or inductive energy harvesting for maintenance-free operation.

Applications

• Smart Manual Assembly Stations

• Calibration & Quality Verification

• Aerospace and Automotive Torque Audits

• Industrial Maintenance & Field Service

• Interchangeable-Head Torque Wrench Systems (ratchet, crowfoot, open-end, flare, tube nut)

Advantages

• Transforms a traditional manual wrench into a wireless, data-logging smart torque tool.

• This system enables traceable torque verification without complex wiring or external modules.

• Compatible with ZIPPTORK Smart Controllers (TCA/TCB/TCC) and IIoT Gateways.

• Supports OT → IT → IIoT → MES integration for digital torque traceability.
