SPC372J Flow-Through Viscometer
Immersion Viscometer for Viscosities from 0.2 to 20,000 centiPoise
|
|
Operating Principle The Model SPC372J is a flow-through viscometer that is installed in laboratory and 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 the actual temperature in the measurement chamber.
The Model 372J viscometer installs directly into a 1/4 inch process line using 1/4 inch NPT fittings on the sensor. The sensor comes with a removable jacket which can be plumbed with process material for excellent temperature tracking or a separate flow line for temperature control of sample material.
Measurements can be made in 13 different viscosity ranges within an overall span of 0.2 to 20,000 cP or the equivalent cSt. Recommended flow rate over the sensor is 0.5 to 1.0 ft/sec.
