The strain sensors DA54-mag, DA54-tiewrap are suitable for high-resolution detection of
forces and deformation of structural works such as bridges, silo legs, offshore wind farms,
railway lines, etc.
With these models in an anodised aluminium housing, the same performance features are
achieved as when applying strain gauges (DMS) directly. These features include a high
resolution, very low drift effects and the options for both static and dynamic measurement.
The strain sensor includes a completely wired DMS that is pressed onto the component by
a specially formed pressing mechanism when screwing on the extension sensor. An
integrated seal provides an initial layer of protection against dust and damp. Depending on
the planned duration of use, measures to protect against damp, such as waterproofing the
joints with silicone, encapsulation with additional surrounding hoods, etc. are applied after
installation.
Unlike strain sensors DA40 and DA54, the pressure strength is generated by integrated
high-performance magnets or cable ties. Time-consuming drilling of threads is not required
as a result.
The strain sensors are equipped with different strain gauges depending on the application.
Type FAE4 and FAED4 full bridges and FAET and FAED half bridges or FAE single grids
are used.
