STA Series Wireless Swing Type Torque Transducer

STA Series 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 STA Series 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

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

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

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

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

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% 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.
