  • Dome-shape tuning fork transducers for corrosion monitoring
    Patent number: 11391698
    Abstract: Embodiments of tuning fork-based sensors are disclosed. The sensors may include a measurement sensor that includes a diaphragm disposed on a proximal end and a plurality of forks extending from the diaphragm toward the distal end of the sensor. The diaphragm may have a domed geometry defining a curved surface. The plurality of forks may extending from the curved surface of the diaphragm toward the distal end and each of the plurality of forks may include a stub portion connected to the diaphragm, a stem portion, and a paddle portion. Some sensors, such as measurement sensors, may include a stem portion formed from a corrosive material. A reference sensor may be provided to compensate for changes in frequency measurements due to temperature, viscosity, or other environmental factors present in the environment where the sensors are deployed.
