Product description

Strain gauges for the construction of sensors. The carrier material of this strain gauge is PEEKF with 40μm thickness. The constantan measuring grid (3 ... 5μm) is covered with PEEKF foil, also with 40μm thickness. As a result, this strain gage type is generally slightly thicker than comparable types with polyimide carrier and cover. In terms of handling, this DMS type is therefore somewhat more robust. Unlike polyimide, PEEKF is not hygroscopic, so that additional sealing of the upper polyimide cover film with epoxy resin is not necessary.

Due to the combination of PEEKF and Konstantan measuring grid, this Strain gauge type is particularly stable in the zero signal and is characterized by very low temperature-induced drift of the zero signal. The temperature-related drift due to expansion of the sensor body is compensated in a wide range from -10 ° C to + 120 ° C for the materials steel (variant 1) and aluminum (variant 3). The permitted operating range is from -40 ° C to + 200 ° C. There are 107 load cycles with ± 1000μm/m achieved with a shift of the zero signal less than 300μm/m.

The gage-factor of the Transduce strain gauges is approx. 2 and is not individualized unlike as for stress analysis gages. The tolerance of the gage factor for measuring grids greater than 1.5mm grid length is ± 1.0%.
