Two strong magnets press the strain gauge of the patented sensor QE1008-W onto the material
to be measured.
The strain gauge is located under the foil between the two magnets. The magnets press the
strain gauge that strongly onto the surface that transmission through friction occurs. The surface
strains are hereby transmitted directly onto the strain gauge which creates the same effect of an
applied strain gauge (bonding).
The individual sensors can be used for applications such as strain measurements on tie bars
with different diameters to stress analyses on at surfaces.
The press-on technology of the QE1008-W enables the high-precision measurement of strains
with quick and reliable mounting, thus reducing the idle time of the machine to a minimum.
Examples of applications
- Bending compensated tie bar strain measurement
- Tie bar strain distribution on presses (acc. to EUROMAP #7)
- Clamping force measurement on columns
- Measurement on at surfaces
- Replacement of bonded strain gauges
The advantages of this system
- Very high accuracy: <0.5% absolute (like a bonded strain gauge)
- Used for tie bar diameters 45... >1000mm
- Bending compensated measurement
- Reliable and accurate also on at surfaces
- Supplied display software with option to save in CSV le format
- Digital and direct tie bar-related display of force in kN, tons, US-tons or µε
- No cables
- Easy to mount and remove
- Very compact design (suitable for skilled service personnel)
- Minimum space requirements and protected as all accessories are stored in a practical
carrying case.
- No more dirty cables in the machine bed
