Viscosity and Temperature Tracking for any Viscosity Management Application

Cambridge Viscosity’s Model SPC/L392 in-line viscometer sensor provides continuous measurement of temperature and viscosity. The sensor can be used with our ViscoPro electronics to meet any viscosity management application.


Our patented technology is based on a simple and reliable electromagnetic concept. Two coils pull a piston back and forth within a constantly refreshed sample of process fluid. Proprietary circuitry analyzes the piston’s travel time to measure absolute viscosity. A built-in temperature detector (RTD) senses the actual temperature in the measurement chamber.


Measurements can be made in any of the 13 different 20:1 viscosity ranges that are available covering a span of 0.2 to 20,000 cP.


The sensor is designed with a four-bolt stainless-steel SAE Code 61 flange and is easily installed in pipelines ranging from 2” and larger in size. Custom tees are available. The back of the sensor is fitted with a 3/4”-18 NPT fitting to accommodate electrical conduit. The sensor’s self-cleaning feature helps to make it maintenance free in many applications.


*NOTE: ALL ATEX SENSORS ARE SPL ONLY (L = hard wired, C = connector).
