Sensing Endcap Service
This procedure provides instructions for disassembling the sensing
endcap, identifying and replacing damaged components, and assembling
the sensing endcap.
Disassembly
WARNING
Make sure power has been turned OFF at the motor and torque sensor
electronics enclosures before servicing the viscometer.
1. Shut power OFF to the motor and torque sensor electronics
enclosures.
CAUTION
Handle the sensing endcap assembly with care when removing it from the
measuring chamber to prevent damage to the torsion element.
2. Remove seven of the eight screws that secure the sensing endcap to
the measuring chamber as shown in Figure 6-1.
3. While holding the sensing endcap in position, remove the last screw
and carefully remove the sensing endcap from the measuring
chamber as shown in Figure 6-1.
4. Remove the stator mounting screws and remove the stator from the
sensing endcap assembly as shown in Figure 6-2.
5. Refer to Figure 6-2 and remove the Microsyn housing cover as
follows:
a. Using a wrench, loosen and remove the signal cable strain
relief nut. Slide the nut, ring, and insulator down the cable.
b. Remove the screws from the Microsyn housing cover.
c. Rotate and lift the housing cover off the assembly and slide
it down the cable.
6. Disconnect the wires from the Microsyn field coil and ground stud.
7. Remove the Microsyn field coil mounting screws and cable clamp
and remove the field coil from the sensing endcap assembly.
