DR Series Force Transducers | Force Sensors
– For Easy Compensation of Inertial Forces

Patented Force Transducers with Time-Proven GTM Precision for Dynamic Force Measurement from 1.25 kN to 2.5 MN

The patented force/acceleration transducers of the DR series are equipped with two integrated MEMS accelerometers with different sensitivity characteristics. This allows easy and effective determination of any resulting inertial forces occurring in the force measuring set-up or the test bench set-up during dynamic measurements. The innovative solution also eliminates the need for one or more additional external accelerometers. Which is a major advantage for the customer. 

Based on the shear stress measuring principle the load cells of the DR series also feature very high stiffness and a high natural frequency to enable broad dynamic measuring range for industrial applications – the perfect high-precision solution with integrated MEMS accelerometers. Their very broad sensitivity characteristic spectrum likewise makes them suitable for a broad range of dynamic test bench applications.

The robust design and low deformation of the force transducers of the DR series make them ideal for dynamic test benches of materials and components in the automotive, aviation, aerospace and energy sectors.
