Cambridge Viscosity's line of in-tank process sensors now make it possible to measure viscosity, temperature and temperature-compensated viscosity (TCV) in any size vessel from less than 1 liter to several thousand tonnes. The sensors are capable of measuring viscosity from 0.2-20,000cP (mPas), cSt, SSU or Cups and can be adapted for insertion up to 4.5m (15ft).

The Model SPL-321 (as shown) is one of our many in-tank process viscometers that are installed in process fluids to provide continuous temperature and viscosity tracking. Our technology is based on a simple and reliable electromagnetic (EMV) or oscillating piston 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 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.

Measurements can be made in 13 different 20:1 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 10ft/sec (3 m/sec).
