Mode Analysis of a Resonant Viscosity Sensor Based on a Torsionally Oscillating Pipe

Beschreibung

We investigated the vibration characteristics of the torsional oscillation mode of an earlier proposed resonant viscosity sensor based on vibrating pipes. To do so, the sensor housing is opened, so that half of the resonator is freely accessible. The actuation and readout of the sensor is realized with electromagnetic coils on the remaining part of the housing and the oscillation velocity is measured on different positions on the uncovered sensor surface. We demonstrate the feasibility and suitability of the electromagnetic readout principle and identified an additional spurious oscillation. All measurements were performed with an air filled resonator to minimize the damping and maximize the oscillation amplitudes.
