DD1 Displacement Transducer：Measuring Displacement and Strain with an Accuracy Class of 0.1
Thestrain-gauge-based DD1displacement and strain transducer measures displacements in a range of±2.5mm very accurately，offering the HBM accuracy class of 0.1.It is a unique product in the market due to its wide range of possible applications.The DD1can be used in materials testing as well as for monitoring tasks，for instance，as a settlement sensor in the monitoring of buildings and in research and development tasks。
The DD1is based on a displacement transducer that converts the displacement of a probe tip into an electrical signal.The DD1has become the proven standard in many strain measurement applications owing to its wide range of accessories，such as a quick clamp set，extensions， and probe blades.It has proven to be a useful and reusable alternative to bonded strain gauges for tensile tests in materials testing.The DD1 has a creep value that is very close to zero owing to the use of a special strain gauge developed by HBM.The sensor can be used at frequencies of to 50Hz，there fore， provides detailed results in dynamic applications.The transducer is renowned forits very low weight and compact dimensions.The quick clamp set enables the transducer to be flexibly fixed to awide range of objects.Integrated stops at both ends protect the DD1 from overload， and the full-bridge technology allows fast integration into existing measurement systems。
