应变传感器

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.

Adapt the Baumer force and strain sensors to match your application task of precise force measurements and benefit from smart features for maximum results. Used in combination with the Baumer Sensor Suite, you will fully exploit the capabilities of the force and strain sensors thanks to specific Add-ons and the intuitive user interface. Watch the tutorial and learn more about the Baumer IO-Link portfolio of force and strain sensors.

堡盟应变传感器通常由弹性体和应变片组成。应变传感器通过螺栓固定到机械构件上。机械构件在力的作用下发生形变，形变通过摩擦力被弹性体捕捉到，导致材料表面发生应变。该应变通过贴在弹性体表面的应变片测得。应变片将机械应变转换为电阻变化，相当于一个机械电子信号转换器。各应变片以特定方式连接成惠斯通电桥，即便是微小的应变也能测量到。这样，借助应变片测得的应变可以很容易地通过内置的放大器进行处理，同时此应变和应力的变化成正比。
