RheoSense Chip Measures at High Shear Rates
- Published: June 29, 2012
SAN RAMON, CA | RheoSense has introduced its E chip said to expand the range of viscosity measurements with significantly greater shear rates. Mounted on the m-VROC viscometer, the E chip attains 2,000,000 1/s measurements of water-like viscosity or 1,000,000 1/s for various inkjet inks (~ 4 mPas).
Industrial processes such as inkjet printing and coating include high shear flows. Reportedly, using the E chip eliminates the onset of early turbulence. The well-defined, micro-fabricated uniform flow channel of the E chip maintains the laminar flow at high shear rates, producing accurate measurements, company says. This viscosity measurement is facilitated by the higher full scale pressure of the chip.
