Miniature sensors take the strain even in confined spaces

Miniature sensors take the strain even in confined spaces

Maintaining and improving process performance along with optimising quality control, whilst meeting the latest safety standards requires reliable data collection from a range of control systems. Force measurement sensors are vital components in some applications and when the challenges are limited space or machinery has small structural dimensions, Baumer says its DST20 miniature strain sensors are an ideal solution.

DST 20 sensors are a compact and cost-efficient solution for measuring forces above 10,000 N even in confined spaces. Overall dimensions of 28 x 12 x 10mm ensure outstanding space savings for a screw-on type strain sensor, combined with a robust stainless steel housing and certification for IP 65 degree protection.

They are designed for demanding production environments and applications such as mechanical and process automation and can be easily integrated into systems with minimum engineering effort. The result is a durable and lasting force measurement solution which can replace cold bonded strain gauges in limited space systems.

Similar to other strain sensors in the Baumer portfolio, DTS20 sensors are based on the strain gauge technology with a strain gauge and strain body featuring ‘soft’ geometry on the inside which minimizes 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, saving valuable time in the case of emergencies.

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, depending on the steel quality. This means a single sensor can be used to cover a larger number of applications, thereby reducing costs and space.
