Depending on the thin film that is used, foil SG are implemented which achieve a gauge factor of up to 30. Depending on the corresponding requirements, specific thin films can be offered or developed to satisfy the needs of the particular application. Besides the gauge factor, the focus is also on stability, temperature-sensitivity and, of course, reproducibility. The possible characteristics at a glance:
Our technical dapartment will be glad to answer any questions which you may have. CeLaGo Sensors recommends prior testing of the SG in your application field.
There is therefore a wide range of SG on offer depending on the emphasis
of the requirements.

*the gauge factor can variate up to 1 dependent on design and compensation
By compensating the apparent strain due to the thermal expansion of the transducer, the temperature sensitivity of the single resistor can already be decisively suppressed. Adjustments to the following coefficient of expansion of the transducer materials are available:
**Due to the production the adjustment accurancy is 3 ppm/K.
In addition to a number of standardized layouts, customer-specific forms can also be supplied. The classification of the measuring grid arrangements is according to the table:
