Wireless Rotary Torque Transducer - 100 Nm to 10 kNm

Introduction

The AxialTQ is a compact and high precision dynamic torque meter. The system consists in a Rotor (torque meter + telemetry emitter), a Stator (telemetry receiver) and output module.

The rotor measures the torque with a high precision sensing element and strain gages, the electrical output is converted from an analog to a digital signal in the rotor. The high accuracy of the system is based on this combination of the proven sensing element technology with performant electronics to provide the highest quality torque measurement available in the industry.

The combination of power transfer and communication technologies allow for contact-free operation minimizing uncertainty. Power is transferred from the stator coil to the rotor coil with an axial separation gap to minimize the chance of contact and damage. The rotor and stator communicate through a 2.4 GHz link for rotor configuration, software updates and high speed transmission of the digital torque values. The rotor and stator are not a matched pair and any stator can be used with any rotor of the same DIN size.

Installation

The rotor interfaces of the Axial TQ consist of two flanges. It is essential to monitor the alignment of the shafts during assembly, in order to minimise radial forces on the torque meter. The stator is connected to the frame, approximately 3 mm from the rotor antenna.
