Description
The N2, N3 and N4 are capacitive, liquid based inclinometers with integrated sensor electronics. They are manufactured with an analog DC output. The sensor electronics require only minimal power and are in conjunction with the capacitive primary transformer characterized by high accuracy, a high signal-to-noise ratio 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 N2, N3 and N4 are suitable for applications requiring a small, light sensor for measurement of relatively large inclinations. Typical areas of application include measuring instruments and inspection systems, vehicles, automation and safety engineering, scientific devices, medical and communications equipment as well as navigational systems.
