Miniature strain sensors measure force in applications in limited space or in machinery with small structural dimensions
With dimensions of just 28x12x10mm, the DST 20 sensors from Baumer can measure forces above 10 kN even in confined spaces. The screw-on type strain sensor also has a robust stainless steel housing and certification for IP 65 protection.
Similar to other strain sensors of this type, the DTS20 sensors are based on a design that uses a strain gauge and strain body featuring “soft” geometry on the inside which minimises hardening of the structure to be measured. This makes the sensor suitable for both static and dynamic applications as well as enabling thin structures to be monitored because of the limited reaction forces on the screws.
The sensor is typically measured with an output signal of around 1.0mV/V which usually 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 micrometre range.
DST20 sensors are available in two measurement ranges of 500 and 1000 µm/m for different requirements in terms of expected strains and permitted mechanical tension. This means a single sensor can be used to cover a larger number of applications, thereby reducing costs and space.
