Abstract
A sensor is provided having a diaphragm. One side of the diaphragm is arranged to be exposed to a fluid, to measure a characteristic of the fluid. Two supports are mounted on the diaphragm and a resonator is provided on the supports. The proportion of energy transferred from the resonator to the diaphragm is variable for the sensor to be used either as a viscosity/density sensor or as a pressure sensor.
