Calibration of inclination angle sensors and dynamic rotation

The in-house calibration laboratory at SPEKTRA GmbH Dresden has expanded its portfolio to include the calibration of inclination angle sensors and dynamic angular rate.

Inclinometers can now be calibrated at DAkkS level in the angular range from 1 degree to 90 degrees relative to the Earth's gravity vector, by inclination in the static gravitational field of the earth. The sensor is therefore positioned on a tilt table and calibrated in various angular positions.

Another new feature is the calibration of acceleration measurement technology with static excitation in the Earth's gravitational field – at DAkkS level. This is a primary method that is applied with very high accuracy. This method can also be applied to calibrate e.g. decelerometers from the automotive sector.

Angular velocity sensors, angular acceleration sensors, and measuring devices can now be calibrated with sinusoidal excitation in the frequency range 0.5 Hz to 200 Hz at DAkkS level with rotational input values angular velocity and angular acceleration and traced back to the national standard. In contrast to previous methods, in which a calibration was carried out by means of a static excitation (constant rotation rate), this new dynamic approach was established and accredited at SPEKTRA. This makes it possible to record the frequency response and phase angle as well as transit time of rotational metrology and to document all in a DAkkS calibration certificate.
