N2 - Miniaturized resonating viscosity sensors operating at frequencies in the low KHz-range offer portability and results comparable to existing lab viscometers. In this paper we will briefly describe a viscosity measurement cell based on a concept that we proposed earlier utilizing electrodynamic-acoustic resonator sensors with a design based on interchangeable resonator cards, which allow for ease of maintenance of the device and provides higher measurement repeatability. Experimental results obtained with the new resonator cards show the clear dependence of the resonance frequency and Q factor on viscosity. In addition, an experimental approach is taken to study the effects of magnetic field variations on the Q factor of the investigated resonators which are suspended by S-shaped (meander) beams and operating either in air or liquids.
