Article: One spring element for all cases- High-precision torque sensor for flexible measuring

Torque measurements in automotive applications often present a special challenge. In some applications, there is a preference for covering multiple measuring ranges with only one torque sensor. There are several approaches for a solution to this challenge.

The measuring range of the sensor can be extended electrically or mechanically, for example. In the first case, however, accuracy suffers because factors contributing to measurement uncertainty such as hysteresis, signal noise and the temperature response of the zero point are reinforced with the spread of the measuring range. In the other case the mechanical properties deteriorate due to the highly complex structure of the measuring body.

HBK has therefore followed a different approach, developing the T12HP digital torque flange with FlexRange. This sensor covers the entire measurement range with only one spring element, with an enormously high level of accuracy.
