Rotary torque sensor WRT

High precisewirelessUSB

Overview
The WRT is a wireless rotary torque transducer that captures torque and angle together with the measurement trace for quality control and tool verification. It operates via an intuitive web user interface without dedicated software or extra server hardware, enabling fast onsite checks and simplified calibration workflows.

Main capabilities

• Simultaneous capture of torque and angle with recording of the measurement curve/trace.
• Local database and results accessible through a web UI on PC, tablet or smartphone.
• Wireless operation for quick checks in hard‑to‑reach applications; also supports USB wired connection.
• Large onboard memory to store up to 50,000 results and 5,000 curves.
• Multiple connection modes: embedded access point (DHCP/Web), infrastructure (network) mode or USB.

Key facts

• Web user interface: view live results, curves and database entries and download data directly from any device.
• Battery life: typically around 8 hours of operation.
• Memory capacity: up to 50,000 results and 5,000 curves stored locally.
• No dedicated software required — web UI only.
• Torque accuracy: typically ±0.5% of reading.
• High angular resolution enabled by magnetic ring sensing.
• Optical transmission / brushless design for increased durability and compatibility with pulse tools.
• Flexible connection options for fast integration in production environments.

Use cases & benefits

• Rapid tool verification and calibration without additional hardware.
• Ensures traceability and compliance of torque and angle measurements in quality control processes.
• Reduces downtime associated with verification thanks to wireless operation and onboard storage.
• Compatible with a wide range of tightening tools (click wrenches, slip wrenches, pneumatic tools, direct‑drive nutrunners) for measurement and traceability.

How it communicates

• Embedded access point (DHCP/Web) — WRT exposes a local Wi‑Fi access point for direct connection.
• Infrastructure mode — WRT joins the customer network for LAN access.
• Wired connection (USB) — alternative method where required by the environment.

Technical specifications

• Captured data: torque, angle, measurement curve/trace.
• Battery life: ~8 hours (typical).
• Local memory: up to 50,000 results and 5,000 curves.
• Torque accuracy: ±0.5% of reading (typical).
• Angle resolution: high resolution using magnetic ring technology.
• Data transmission: wireless (embedded AP or infrastructure) and wired (USB) options.
• Design: optical transmission (brushless) for improved durability, especially with pulse tools.
• User interface: browser‑based web UI — no dedicated software required.
