Resumen:
High precision measurements and monitoring of tilt or inclination are essential in the field of ultraprecise force and mass measurements. We present a new concept for high resolving tilt/inclination measurements. Therefore a commercial electromagnetic force compensation (EMC) weigh cell is mounted in a hanging position and loaded with a defined weight. Thus the system conforms to a pendulum. By measuring the tilt depended deflection of the pendulum with the position sensor of the weigh cell we achieved a standard deviation of 7.1 nrad (3.4 nrad filtered) within a sampling time of 15 min. In future investigations we will compensate the deflection and take the compensation force as a measure for the tilt.
