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.
