Principle of Operation

1IPUP 4FOTPS 4MJU %JTD "
Motor rotation is transmitted to the rotor via a tor-
sion wire. Viscous torque acts on the rotor turning
1IPUP 4FOTPS 4MJU %JTD #
in the measured fluid. The torsion wire rotates with
the wire in a deflected state at an angle which is
proportional to the size of the viscous torque. The
angle of deflection of the torsion wire is the same
as the reciprocal deflection of slit discs A and B 5PSTJPO 8JSF
which are attached to the ends of the torsion wire.
Each slit disc’s photo sensor read the deflection
angel of the disc and this information is converted
into a viscosity measurement which is displayed.

A magnetic bearing positioned at the lower part of
the torsion wire provides non-contact support of
the rotor spindle.
