Strain gauge LA11X

LA (Linear)

Linear Strain Gauges of A series coming with one measurement grid measuring on direction of strain. Typically 4 gauges are interconnected to form the wheatstone bridge.

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

A Series Transducer Strain Gauges: Ensure Maximum Precision and Quality of Your Transducers

The A series universal strain gauges are optimised for transducer manufacturers. Combining the most common constantan measuring grid foils with a high-performance modified PEEK carrier material provides strain gauges that unite easy handling with high accuracy and outstanding humidity behavior. 

A series come 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.
