Baumer introduces DST20 strain sensors

July 2, 2020 - The miniature-format strain sensors DST20 complement the Baumer portfolio by adding a
solution for measuring large forces above 10,000 N even in confined spaces. With their dimensions of 28x12x10 mm, the DST20 miniature strain sensors are intended to offer space savings.. At the same time, their stainless steel housing and a certification for the IP 65 degree of protection make them suited for use in rough production environments and for a large range of applications, such as mechanical and equipment engineering as well as process automation. The DST20 strain sensor can be integrated into a machine with minimum engineering effort and offers a lasting solution that can serially replace cold bonded strain gauges in limited installation spaces, based on initial tests in the experimental laboratory.
Similar to other strain sensors in the Baumer portfolio, the 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.
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.
