The DKA-20(S) is a robust strain link transducer sensor that can be attached to its base by screws. Due to its closed structural design which is made of galvanized stainless steel, the device can be used for indirect strength measuring and the extension of machine elements and components in a rough environment. The high transmission ratio is a feature of this new class of strain link transducers.

The installation is most simple by merely mounting the sensor with four M6 bolts to a plain surface of the material, which makes any direct bonding and the adjustment of extension measuring tapes superfluous.

The device can be used for monitoring forces, metering the filling level and recording the extension of building components predominantly made of steel and aluminum, to name just a few fields application. The signal, the temperature behavior and the transmission ratio are based on the principle applied and depend on how both the geometry and the material of the sensor and the component are mated.

Ideally, the sensor will therefore be calibrated best by applying a known force to the component concerned under the ambient conditions that are typical of the measurement.

The following further features are for indicating the there DKA-20(S):
passive surface strain sensor with full bridge, for cyclical applications, suitable for strain measurements on rigid structures, sensor exchange w/o recalibration.
