Cambridge Viscosity has developed a new small flow-thru sanitary process viscometer, the SPL-374, for highly accurate and repeatable viscosity readings, clean-in-place simplicity and tight temperature control for small diameter process loops. Its initial uses are across a range of biopharmaceutical and R&D applications.

The new SPL-374 sensor directly connects into a ¼” (6mm) process line using sanitary connections. The sensor requires less than 5mL of sample to accurately determine the viscosity of a solution. The SPL-374 also has an integrated heater for tight temperature control under flow conditions up to 1 ft/sec. The small sample size requirements, integrated heater and quick release connections make it ideal for miniature or small-scale research projects.

Coupled with Cambridge’s standard VISCOpro2000 or VISCOpro1600 electronics, the small process SPL-374 sensor’s sanitary interconnects and integrated heater achieve precise temperature-controlled measurements. The integral heater results in excellent temperature control without needing to control the entire line of flow.

The SPL-374 sensor is based on Cambridge’s patented electromagnetic technology. Two coils within the sensor move a piston back and forth at a constant magnetic force. Proprietary circuitry analyzes its two-way travel time to measure absolute viscosity. Because all wetted parts are stainless steel and the piston is in constant motion, the sampling area is continually scrubbed clean. There is no need for frequent calibration and very little maintenance is required.
