Miniature strain sensors measure large forces even in confined spaces

Similar to other strain sensors in the Baumer portfolio, the compact DST20 sensors are based on the strain gauge technology with a strain gauge and a strain body. The soft geometry on the inside minimizes hardening of the structure to be measured. This makes the miniature strain sensor suitable for static as well as dynamic applications. Thin structures can also be monitored because of the limited reaction forces on the screws.

Ex factory the strain is typically measured with an output signal of around 1.0 mV/V, which frequently eliminates the need for calibration with a separate force sensor. This allows users to benefit from simple and quick commissioning coupled with high measurement accuracy in the micrometer range, which saves valuable time in the case of emergencies.

The sensors come in two measurement ranges: 500 and 1,000 µm/m, for different customer requirements in terms of the expected strains and permitted mechanical tension, depending on the steel quality. This way, a single sensor can be used to cover a large number of applications, allowing users to reduce costs and warehouse space.

With the DST20, Baumer rounds off its strong portfolio for force measurement with force and strain sensors. In addition to robust strain sensors for outdoor and industrial applications, Baumer has thus combined robustness and precision with exceptionally compact dimensions, effectively enhancing the scope of application of strain sensors. Users can now also optimize their process safety and quality in areas where the smallest dimensions matter.
