Description
The NG2, NG3 and NG4 are capacitive, liquid based inclinometers with integrated sensor electronics. They are manufactured with an analog DC output and, optionally, a pulse-width modulated PWM signal. The sensor electronics require only minimal power and are in conjunction with the capacitive primary transformer characterized by high accuracy and high long-term stability. The measurement technique enables a linear relationship between the angle to be measured and the output signal. The determined angle is independent of the local gravitational acceleration, that means that no matter where the measurement is being taken, whether in Europe, Australia, on Mount Everest or on the moon, the inclination will be measured correctly anywhere.
Application
The inclinometers NG2, NG3 and NG4 are suitable for applications requiring high measurement accuracy with low linearity deviations and high long-term stability for measurement of relatively large inclination angles. Typical areas of application include construction, mining, vehicles, surveying equipment, aircraft, transportation and conveyor systems as well as ships.
