Inclinometer for inclination measurement in the range of ±10 degrees
NB3 is a static accelerometer preferably employed for measuring
The sensor's primary transformer consists of a capacitive spring-mass system with gas-dynamic damping.
The sensor is manufactured either with an analog DC or a pulse width modulated output. The integrated sensor electronics require only minimal power and are in conjunction with the capacitive primary transformer characterized by high accuracy and long-term stability.
The NB3 is
suitable for applications requiring a small, light sensor for
measurement of relatively small inclination angles.
Typical areas of application include measuring instruments and inspection systems, vehicles, automation and safety engineering, scientific devices, medical and communications equipment as well as leveling systems.
