DD1 Displacement Transducer: Measuring Displacement and Strain with an Accuracy Class of 0.1

The strain-gauge-based DD1 displacement and strain transducer measures displacements in a range of ±2.5 mm 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 DD1 can 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 DD1 is based on a displacement transducer that converts the displacement of a probe tip into an electrical signal. The DD1 has 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 up to 50 Hz and, therefore, provides detailed results in dynamic applications. The transducer is renowned for its very low weight and compact dimensions. The quick clamp set enables the transducer to be flexibly fixed to a wide 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.
