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 relati***hip 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 inclinati*** using accelerometers, this measurement principle enables a linear relati***hip between the inclination to be measured and the output signal, independent of the c***tant of gr***ity 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 requiring ***all and light devices, replacability, measurement of relatively large inclinati*** and a normalised, analogue voltage output signal.
Measurements of inclinati*** 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 n***igation systems are typical examples.

Description
The NG2I, NG3I and NG4I are capacitive and liquid based inclinometers with integrated sensor electronics and current amplifier. Electronic temperature compensation makes up for the temperature drift of the sensitivity of the primary transformer. An integrated, highly stable voltage regulator ensures stable operation for a range of supply voltages.

The measuring time c***tant can be matched to the requirements of the measurement task by appropriate ha***are programming.
The power is obtained from the measurement current loop, thereby eliminating the need for a separate power supply and enabling operation with two wire connection.
Application
The NG2I, NG3I and NG4I are suitable for applicati*** requiring high measurement accuracy with high linearity and temperature stability as well as high long-term stability for measurement of large inclination angles and for which the power is to be supplied via a 4...20mA current loop without the need for a separate supply voltage.
