Cambridge Viscosity SPC322

Operating Principle

The Model SPC322 is an in-line process viscometer that is installed in process fluids to provide continuous temperature and viscosity tracking. Our technology is based on a simple and reliable electromagnetic concept. Two coils move a piston back and forth magnetically at a constant force. Proprietary circuitry analyzes the piston's two-way travel time to measure absolute viscosity.

A deflector, positioned over the piston, moves the fluid into the measurement chamber. This feature, coupled with the constant piston motion, keeps the sample fresh and mechanically scrubs the chamber. A built-in temperature detector (RTD) senses actual temperature in the measurement chamber.

The model SPC322 viscometer can be immersed directly into a blend tank or a vessel. The "Big Dipper" provides continuous, accurate measurements of mixing and blending viscosities, as well as reaction tracking.

Measurements can be made in 13 different viscosity ranges within an overall span of 0.2 to 20,000 cP or the equivalent cSt. Maximum flow rate over the sensor head is 12ft/sec (3.66 m/sec).

One of the industry's most unique viscometers for in-tank blending & reaction monitoring
