Transducer Class Multi-Grid Strain Sensors by Micro-Measurements

For Multi-Axis Force, Axial and Torsional Load Measurements design Based on Advanced Sensors Technology

180

The Micro-Measurements brand of Vishay Precision Group, industry innovators in the design, development and manufacture of resistive-foil sensors for high-precision strain measurements, on May 24, announced the introduction of its S5060 Series, a new line of Transducer Class multi-grid advanced strain sensors.

The Series is designed to facilitate reliable, accurate, cost-effective multi-axis force, torque/axial and torsional load measurements within robotics, factory automation, machinery and tooling, agricultural and off-highway vehicle, and materials testing applications. They may be further used to convert automotive components into force sensing devices.

Design of the Micro-Measurements S5060 Series incorporates VPG’s own proprietary Advanced Sensors Technology, from which a specialty arrangement of both shear and axial half-bridge circuits is configured and installed with a common carrier backing. Customers can choose from among multiple resistance values and gage patterns, in support of a diverse array of bending, torque/shear and thrust measurements.

When installed in pairs, the circuitry pattern of the S5060 Series may be used to construct both a full-torsion bridge and a full-Poisson bridge, via the installation of just two strain sensors. The alignment of a single pair automatically aligns all other grids installed on the common backing for improved grid-to-grid placement accuracy, optimized installation time, and reduced material and solder connection requirements. The number of required circuit refinements for initial zero balance, as well as temperature compensation for zero balance, are further reduced via improvements in resistance tolerance (±0.2%) and grid-to-grid thermal performance matching specifications. These combined attributes allow Micro-Measurements to offer a simple, industry-exclusive solution for torque/axial and torsional load measurements, with minimal alignment and linearity issues. Finished transducer designs can therefore remain reliable-yet-cost-effective, without sacrificing accuracy and performance.
