Viscosity Sensor: Measurement Range 1-100,000 cP

Q: How often should a viscosity sensor be calibrated?

Calibration should be performed every 6-12 months or according to the manufacturer's recommendations, using certified viscosity standards to maintain accuracy.

Q: Can viscosity sensors handle abrasive or corrosive fluids?

Yes, with appropriate material selection (e.g., hardened coatings, corrosion-resistant alloys) and proper maintenance, they can be used in harsh environments.

Component Specifications

Definition

A viscosity sensor is an industrial instrument that measures the resistance of a fluid to flow, providing real-time data for automated viscosity control in mixing and processing systems. It typically employs rotational, vibrational, or capillary measurement techniques to determine dynamic or kinematic viscosity, ensuring consistent product quality and process efficiency.

Working Principle

Operates by measuring the torque or damping effect on a vibrating or rotating element (such as a probe, spindle, or tuning fork) immersed in the fluid. Changes in fluid viscosity alter the oscillation frequency, amplitude, or required driving force, which are converted into an electrical signal proportional to viscosity.

Materials

316L stainless steel wetted parts, PTFE seals, ceramic or hardened steel sensing elements, epoxy-coated electronics housing
