TTES / TTAS Series Wireless Rotary Torque Transducer (Square Drive)

(Also known as Wireless Rotary Torque Sensor – Square Drive Type / Non-Contact Torque Transmitter for Impact & Pulse Tools)

A TTES / TTAS Series Wireless Rotary Torque Transducer (Square Drive) is a non-contact, high-speed torque sensor designed to measure and transmit real-time torque and angle data from rotating power tools that use square-drive sockets (such as impact wrenches, pulse tools, or torque multipliers).

It replaces traditional wired or slip-ring sensors with a wireless data transmission system, enabling accurate torque measurement under dynamic, high-vibration, and high-RPM conditions — ideal for industrial bolting, assembly, and quality verification applications.

This transducer type is designed for use in pneumatic, hydraulic, or electric torque tools.

Working Principle

1. Torque Sensing:
   Strain gauges are bonded to an internal torsion shaft within the transducer.
   When torque is applied through the square drive, the shaft twists slightly, causing a change in resistance proportional to the applied torque.

2. Signal Conditioning:
   The analog strain signal is converted into a digital torque value by an onboard circuit.

3. Wireless Transmission:
   Data is transmitted contactlessly to a fixed receiver unit using RF (2.4 GHz), Bluetooth — no slip rings or cables required.

4. Data Output & Integration:
   The receiver sends torque and angle data to a controller, PC, or tablet via USB, enabling real-time monitoring, recording, or closed-loop control.

Key Features

• Square Drive Interface:
  Standard male or female square drives (e.g., ½″, ¾″, 1″, 1½″) for direct tool connection.

• Wireless Data Link:
  2.4 GHz or Bluetooth transmission — eliminates cable drag and slip ring wear.

• High Accuracy:
  ±1 % F.S. depending on model and range.

• Dynamic Range:
  Supports both static and impact torque up to 10,000 rpm rotational speed.

• Anti-Vibration Design:
  Reinforced and vibration isolation design for use with impact and pulse tools.

• Real-Time Data Output:
  Torque, angle, and cycle count can be displayed, logged, or integrated into MES/IIoT systems.

Applications

• Pneumatic & Electric Impact Wrenches

• Hydraulic & Pneumatic Torque Multipliers

• Torque Calibration Benches & Dynamometers
