Correlates with ASTM D7483 and ASTM D445
The high pressure viscosity sensors 440 and 443 are used in various applications including PVT oil research, EOR, core analysis, and supercritical fluid research. Fluid flows through a 1/4 inch high pressure port for measurement in which the fluid may be measured under low flow or static conditions. A Cambridge Viscosity system measures viscosity, temperature, and temperature compensated viscosity. It provides data via a RS-232, RS-485 or 4-20 mA signal.
Both sensors install into a high-pressure, pump-through type system. Both ends mate to HiP HF4 fittings with a 9/16-28 thread. The 440 high pressure viscometer sensor is rated for continuous operation up to 20,000 psi and is static tested to 30,000 psi while the 443 sensor is rated up to 30,000 psi.
Our industry leading viscosity technology is based on a simple and reliable electromagnetic concept, which is utilized in every Cambridge Viscosity sensor. Two coils move the piston back and forth magnetically at a constant force. Proprietary circuitry analyzes the pistons two-way travel time to measure absolute viscosity. A built-in temperature detector (RTD) senses the temperature of the sampling chamber.
