| Description: | Conventional linear encoders with their conflicting goals of resolution, measuring range and accuracy fail under the harsh conditions of building diagnostics. A new sensor is to be used to create an absolutely encoded measuring system with high adjustment and thus user-friendliness. The integrated adjustment aid is only achievable with microsystem technologies and significantly simplifies the assembly process. This leads to robust and low-cost products that open up the market more broadly. Result: Robust length measuring device for building monitoring with absolutely coded measuring system - Thus safe when restarting after power failures. Integrated temperature and humidity sensor as well as data logger with timer. Via battery buffer also mains-independent measuring operation for long-term monitoring is possible. Developed sensor components: - Scanning systems with 10µm and 40µm smallest track period (incl. scanning apertures and scales). - Mounting concept/technology, including layout and pin assignment of the carrier PCB as well as mounting tolerances and adjustment criteria - Lighting concept Achieved features of the system solution: - Absolutely coded and thus fail-safe measuring system - Modular system with grating constants of 10µm resp. 40µm - Thus measuring ranges up to 166 or 665 mm can be covered - Sensor can be used universally for strain, crack, deformation and motion measurements - Integrated alignment control system for robust manufacturing, offering metrological resolutions of 0.05µm at measuring ranges of 30mm. Conventional sensors suitable for structural monitoring are at least a factor of 20 worse in resolution with this combination of features. |
