Description

The QTA152 micro reaction torque sensor is one of the smallest torque sensor in FUTEK’s catalog.

Its unique geometry allows it to fit in applications where precision closed-loop torque measurements have previously not been possible. By matching the motor/gearhead assembly diameter without adding to its size, the QTA152 allows for precise torque measurement in a very dense array, which maximizes the real state utilization of the assembly. Its unique motor mounting provisions do not require adapters, which would increase the system's height and weight.

Allows for multiple mounting configurations
Can mount directly onto a brushless DC motor
A large ID supports the motor shaft coupler
Very thin and flexible cable withstands the tight bending radius and physical stress associated with moving applications
Can be integrated with electronics for custom requirements
High precision and reliability
Ideal for medical surgical robots or any dynamic application
It can be modified to suit OEM applications
Low height (13.1mm) allows easy integration to most joints and motor

Features

5 times smaller than conventional torque sensors
10 times more accurate that current loop torque measurement
Sized to mount to precision servo motors
