Application

The NA2, NA3 and NA4 can be used for measurements requiring small and light devices, replacability, measurement of relatively large inclinations and a normalised, analogue voltage output signal.
Measurements of inclinations in measuring instruments and inspection equipment, in water, land and air vehicles, in automation and safety technology, on cranes and lifting equipment, on robots, in the manufacture of scientific equipment, in medicine and telecommunication as well as navigation systems are typical examples.
