XU (Torsion/Shear)

Shear strain gauges of U series coming with one or two measurement grids measuring one or two (90° shift) direction(s) of strain. Typically 2 or 4 gauges are interconnected to form the wheatstone bridge to measure torsion

Different sizes including miniature designs.
Aluminum or steel adapted temperature response.
Up to 5.000 Ohm resistance.

U Series Transducer Strain Gauges: Enhanced sensitivity and modulus compensated

Combining MODCO (modulus compensated) measuring grid foils with high-performance modified PEEK carrier material provides strain gauges that unite easy handling with high accuracy and outstanding humidity behavior. U series strain gauges also offer a compensated modulus of elasticity, increased sensitivity, and enhanced fatigue strength at high strains.

U series comes in different geometries, resistance values, and grid lengths as standard. Custom designs can be developed in just a few weeks.

Robust

Excellent chemical resistance
Very low water absorption and resistance to humidity
Small radii of curvature are possible, allowing for installation in small drill holes

Easy handling during installation and long service life.

Precise

Very high stiffness (modulus of elasticity) and, thus, capable of transferring the measuring body’s deformation directly to the measuring grid
Higher thermal conductivity than polyimide

Suitable for transducers with high accuracy requirements.

Flexible

Over 30 different standard versions for steel or aluminum with 10 different creep adjustments
Various options available such as encapsulation, pre-coating with adhesive, or pre-tinned solder tabs
Custom designs possible

Perfect for your solution, regardless of whether it is standard or custom.
