Deployment areas and usage instructions
The transducers are intended for measuring static and dynamic
compression force. Because of their extremely small dimensions, the
transducers can also be used in situations where little space is
available. The force transducers are suitable for harsh environmental
conditions and tough operational demands. They are maintenance free
and can also be installed in locations that are difficult to access. The
wide range of output signals allows tecsis force transducers to be
adapted to many difference usage conditions.
As precision measuring devices, the transducers must be handled with
care during transportation and assembly. Shocks (e.g. colliding with a
hard surface) can also cause unexpected overloading during measuring
operation, causing permanent damage.
The limits for the permitted mechanical, thermal and electrical
loads are listed in the "technical data". These must be complied
with.

Design and method of operation
4.1
Measuring element
Innovative transducer manufacturing methods using the DMS principle
have recently been developed. Etched wire strain gauges are not used
in this case. The entire Wheatstone bridge with the necessary
equalisation resistances and temperature compensation is realised
using a thin-film method on a metallic, pot-shaped body. This thin-film
sensor is then welded into in an appropriately shaped measuring spring
with the aid of a laser welding method. The force is introduced into the
force transducer via load introduction bot. The thin-film sensor and the
optional electronics are sealed against moisture and dust.
