测量原理
The Model TV-22
viscometer utilizes a torque balance servo method to detect viscous torque.
The sensing system employs a flat spring bearing. When viscous torque acts
on the turning rotor, a deflection between the drive shaft and the follower
shaft occurs. This deflection is converted to an electrical current
providing a counter force which acts to return the deflection to zero via
the feedback control system on the drive shaft. The electrical current is
transmitted to a torquer which is comprised of a coil and magnet, to
generate a force which zeroes the deflection between the drive shaft and
follower shaft. This zeroing current is detected and converted into a
viscosity value.
