In-Line Viscometer Description
1-10 P/N M/97-520
Component Identification
The following paragraphs provide a brief description of each component
within the TT100 In-Line Viscometer. Refer to Figure 1-5 for the
component location within the viscometer.
Torque Sensor Assembly
The Torque Sensor Assembly contains the torsion element, armature, and
field coil. These components generate an electrical signal proportional to
the viscous drag of the process fluid which is sent to the torque sensor
electronics enclosure for signal processing.
Sensing Endcap
The Sensing Endcap contains the torque sensor assembly and all related
components.
Stator
The Stator, which is mounted on the torsion element, applies torque
generated by viscous drag to the torsion element. The dimensions of the
stator, in conjunction with the rotor, are critical to the accuracy of the
viscometer. Many different stator sizes are available which provide
different viscometer measurement ranges.
Stop Posts
The stop posts limit stator/torsion element movement to prevent torsion
element damage.
Inlet/Outlet
The Inlet and Outlet are provided with an appropriate connection type and
allows process fluid to enter or exit the viscometer. Either connection may
be used to allow process fluid to enter or exit the viscometer.
Rotor
The Rotor is a hollow cylinder which constantly rotates around the stator,
driven by the motor. The rotation of the rotor moves process fluid in the
measuring annulus which results in viscous drag on the stator. Rotors are
available that contain additional surface holes to allow a faster turnover of
process fluid in the measuring annulus. Different rotor sizes are also
available.
