VISCOSITY SENSOR Russian patent published in 1997 - IPC

FIELD: measurement technology. SUBSTANCE: viscosity sensor has tuning fork positioned horizontally. Each leg of tuning fork carries piezoelectric transducer and probe. Two bosses the width of which is less than half the width of legs are coupled to face surface of legs or made integral with the latter. Bosses are shifter relative to tuning fork axle of symmetry in different directions. They are bent to opposite sides so that one boss gets into vacant space near the other. Points of fastening the measuring probes mounted on bosses are arranged in parallel, on one level. EFFECT: higher measurement accuracy. 2 dwg
