DMP41 – A NEW CHAPTER OF ULTRA-PRECISION INSTRUMENT FOR STRAIN GAUGE TRANSDUCERS

A. Schäfer, H. Kitzing

Abstract

The strain gauge principle is a resistive principle. If a strain is applied only a very small change of resistance occurs. By a Wheatstone bridge the change of resistance can be transferred into a voltage. However this voltage signal on the output of the bridge is still very small. Therefore it must be gained by sophisticated methods. This paper describes the new strain gauge precision instrument DMP41 with highest resolution and highest stability for the use in calibration tasks with e.g. force, torque, pressure transducers or load cells.
