Need help with the installation of strain gauges?

We are glad to assist you with your measuring task and provide all the necessary information about strain gauges.

The training can be customized according to your wishes.

Training agenda (example):

Introduction to the strain gauge technique
Explanation of typical bridge circuits
Explanation of various wiring options
Explanation of the steps for the strain gauge bonding
Implementation of the strain gauge application for measuring bending, axial force, torsion and / or shear
Loading of the component and evaluation of the results with the measuring electronics
Calculation of stresses and moments from measured strains

Below you will find the typical steps of strain gauge bonding. They may differ depending on the application.

1. Surface preparation

The DMS application surfaces should have a roughness depth of 0.4 to 1.6 μm before the degreasing and drying is completed.
In this first step, the surface is roughened with an abrasive cloth. Then clean the looped surface in one direction with the lint-free solvent wipes.

2. Mark the strain gauge position

The second step is to position your strain gauge correctly. Just scribble the lines directly on the part with a ruler and a pencil.

3. Strain gauge preparation

Before you glue the strain gauge, find out which adhesives fit best your measuring task.

Strain gauge cleaning with Neutralizer on a cotton swab is also a preparation for gluing.

4. Glueing the strain gauge

Take the strain gauge out of his packing with tweezers and place it with the adhesive side down in the right position on the test object.

Place a short piece of Mylar tape over about 1.5 mm of the strain gauge backing. Raise the composite again at a shallow angle and pull back one end of the composite to pull the strain gauge over the surface.

Coat the entire surface of the strain gauge, including the copper pads, with an adhesive layer.
Also coat the component surface in the area of the strain gauge mounting.

With the help of a polyethylene sheet, press the strain gauge evenly and firmly for about 30 seconds.
