description

the capacitive, dielectric liquid based inclinometers na2-05, na2-10, na3-30, na4-45 and na4-70 contain new sensor electronics.  these are made up of a highly stable, laser-trimmed signal conditioner with electronic compensation for temperature drift, highly stable supply voltage regulation circuitry and low-pass filtering of the measurement signal to eliminate unwanted noise.

the capacitive measurement principle guarantees a very stable, linear relationship between the inclination being measured and the normalised output signal.

the sensor electronics require minimal power and, together with the capacitive primary transformer, are characterised by low errors, high signal-to-noise ratio and high long-term stability.

contrary to measuring inclinations using accelerometers, this measurement principle enables a linear relationship between the inclination to be measured and the output signal, independent of the constant of gravity at the place of measurement, i.e. independently of where the measurement is taking place, whether in europe, australia, on mount everest or the moon.

application

the na2, na3 and na4 can be used for measurements re 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 e, in water, land and air vehicles, in automation and safety technology, on cranes and lifting e, on robots, in the manufacture of scientific e, in medicine and telecommunication as well as navigation systems are typical examples.
