For higher force ranges and large constructions, strain sensors are a suitable alternative to force sensors. Unlike force sensors, strain sensors are not installed directly in the force flow but screwed onto the relevant component surface. The detected surface strain allows for precise force identification without elaborate component modifications.

The product portfolio covers the entire sensor range to meet multifacted requirements and specific applications. The portfolio excels in terms of miniaturized and robust products as well as digital connectivity. Consistency that pays off.

Which strain sensor is the right one for your application, how force measurement with strain sensors is implemented and at which position a strain sensor should be mounted, you will find out in our whitepaper.


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

Standard Baumer strain sensors comprise strain body and strain gauge. The strain sensor is screwed onto a machine structure. The applied force causes deformation at the machine structure which is picked up by the strain body with the help of friction and causing strain on the material surface. The amount of strain is measured by the strain gauge on the strain body surface. The strain gauges convert the mechanical strain into a change in the electrical resistance and act as mechanical-electrical converters. The strain gauges being smartly interconnected to form a Wheatstone bridge allows for measuring even most minor strain. The gauge-measured strain this way generates a change in stress that is proportional to the strain, which can be easily evaluated by the integrated amplifier electronics.
