Principle
The RFND-50B in-line micro-vibration Viscometer works based on the principle of micro-vibration. The Sensor generates micro-amplitude vibration in the fluid, and calculates the fluid viscosity by measuring the vibration damping. At the same time, the integrated temperature sensor can synchronously measure the fluid temperature, and output viscosity and temperature values through 4-20mA signal.
Applications
Silicone oil, Resin, fiber, inks, plastics, asphalt, lubricating oil, fine chemicals in each viscosity section
Standards
HG20592、ExdIIBT6Gb
