STRESS ANALYSIS WITH STRAIN GAUGE ROSETTS

Stress Analysis

We equip your component with strain gauges (DMS). We advise you on the selection and arrangement of the strain gauges.

By using the strain gauge, the level of mechanical load and the direction of the main stresses can be determined in real use and compared with the finite element calculation.

 

STRESS ANALYSIS OF SOLDERED CONNECTIONS

Stress Analysis

The stress analysis is carried out equally on “large” and “small” components. When it comes to determining the stresses on edges, soldering or welding seams, we also use “stacks”. The three measuring grids are then stacked on top of each other. In this way, the principal stresses and the direction of the principal stress can be calculated exactly for the location of the measuring grid.

STRESS ANALYSIS IN THE PRODUCTION OF ELECTRONIC COMPONENTS

Circuit Board Production

During the production of circuit boards, mechanical stresses arise, for example when separating circuit boards or when pressing in contacts.

With strain gauge rosettes, maximum strain and the direction of the strain can be determined.

CONTACT FORCE WITH CHIP CARD READERS

Contact Force Measurement

To measure the contact force in chip card readers, strain gauges are applied to a sheet of steel with tiny bending springs. The strain gauges have a dimension of only 1.9 mm x 1.4 mm.

Circuit boards are used to achieve robust wiring and to ensure good strain relief for the connection cables.

The majority of our products are configured according to your wishes and requirements. From batch size one.

 

ALIGNMENT PROBES FOR CALIBRATION

Miniaturization and Precision

Alignment specimens are important accessories when calibrating force sensors. With the alignment samples, the load introductions of the calibration device are aligned exactly. No moments or transverse forces then act on the test specimen. This is important because incorrect alignment would affect technical data such as linearity, reversal margin, etc.

Alignment specimens are manufactured in various dimensions, with 8 to 12 independent channels.

Strain gauge dimensions N2A-06-S5272H-120: 2.1 mm x 1.2 mm.

The two 12-core, shielded connection cables each have a diameter of 1.8 mm.

SEMICONDUCTOR STRAIN GAUGES

Ultra-Miniature Sensors

Further miniaturization is possible with semiconductor strain gauges. In addition, the semiconductor strain gauges offer the possibility of achieving a high resolution with high overload protection at the same time. The application is complex, and due to the low accuracy, the use compared to metal foil stretch marks needs to be carefully considered.

 

 

MEASUREMENT PLATFORM

Measuring platforms in all sizes

We develop and manufacture sensors in all sizes: from ultraminiature to heavyweight measurement platforms.

The measuring platforms are used when the forces and moments can no longer be recorded by a single force-torque sensor, or when the required support surface is too large.

Application examples include measuring platforms for tire test benches, measuring platforms for sports and rehabilitation, ...
