Our Quality Commitment

Precision and reliability take precedence across all stages of development and production:

  • Development process based on the V-model
  • Strict quality control of engineering, product design, electronics configurations, and selection of high-quality materials
  • Robust, advanced electronics for reliable processing of measurement data
  • Functional tests within the scope of constant testing processes
  • Standardized preloading processes
  • Finite element method (FEM) with comparison of variations and extreme case simulations
  • Testing of optimal conditions and positionings during calibration
  • Sensor precision acc. to EN 61298-2 and VDI/VDE 2637 and 2638
  • Future-proof designs with forward and backward compatibility
  • Retrofitting in existing applications acc. to customer specifications without any redesigning work
  • Full incoming and outgoing inspections with comprehensive documentation 
  • Final inspection with simplified airfreight and customs clearance as “known sender” and “authorized economic operator”
