Applications

Baumer strain sensors allow cost-effective force measurement for nearly all application areas. Regardless of whether in limited spaces, for robust outdoor applications, or the industrial sector, we always offer you the right solution for measuring large forces in ongoing processes.

For limited space – DST20

The DST20 allows the measurement of large forces even in limited space. At the same time, the stainless steel housing of the strain sensor makes it excellently suited for use in rough production environments and for a large range of applications, such as in mechanical and in equipment engineering as well as in process automation.  

Industrial indoor applications – DST53/ DST76

The industrial strain sensor DST allows precise force measurement without elaborate component adjustments. The sensor is easy to integrate into the machine, allowing it to quickly deliver meaningful measurement results for applications such as the control of retention force, process monitoring, or sheet thickness measurement.

Rough outdoor applications – DST55R

The robust strain sensor DST55R is especially suited for outdoor industrial applications such as, for example, vibration damping for mobile automation. Thanks to its robust design and tested long-term impermeability according to proTect+, the sensor guarantees reliable continuous operation under extreme conditions.

Technology

Baumer strain sensors usually consist of a strain body and strain gauges. The strain sensor is screwed to a machine structure with screws. This machine structure deforms with the application of force, and this deformation is picked up by the strain body through friction, so that strains occur on the material surface. The strain is measured using the strain gauges applied to the surface of the measuring body. The strain gauges convert the mechanical strain into an electrical resistance change and act as mechanical-electrical converters. The intelligent connection of the individual strain gauges to a Wheatstone bridge enables the measurement of even the smallest strains. These strains measured with the aid of the strain gauges thus generate a stress change proportional to the strain which can be easily evaluated with the aid of the integrated amplifier electronics.

Functionality of strain sensors

Strain is the relative change in length of a component or structure under stress. Learn more about the functionality of stain sensors.

Force measurement: Force or strain sensor?

Force measurement: Force or strain sensor?

Looking for force measurement solutions usually force sensors are taken into consideration. Especially when it comes to large forces, strain sensors are a cost efficient and clever alternative. When are strain sensors suitable solutions and when is it better to use force sensors? What are the differences between the two sensor types and what are the optimal scenarios for using each?
