Inclinometer type NG2 - NG3 - NG4



NG2 - NG3 - NG4

With high accuracy for measuring in the range of 10, 30 and 80 Degree with non-amplified output / or digital pulse output.



The inclination sensors NG2, NG3 and NG4 are capacitive liquid based sensors with integrated sensor electronics. These sensors can be supplied with an analog DC output or with a digital pulse-width modulated output signal which is linear to the degree of angle. The power consumption of these sensors is very low (approx. 1mA).

The measuring principle assures a linear angle output equal to the measuring range of the sensor with a maximum range of 80 degrees on NG4! This is independent of the size of gravity at the measuring point, so it doesn’t matter if you are in Europe, Australia, or even on the moon, the angle of inclination is measured correctly everywhere.


The NG series is well suited for industrial use where the demands for high accuracy, long-term stability, and relatively large tilt angle measuring ranges are wanted.

These NG series inclinometers have been used with very good results in the mining industry, food industry, bridges, cranes, agriculture machinery, process machines, transport systems and vehicles, plus many other applications as well as OEM systems.
