- The rheonics SRD measures viscosity and density by means of a torsional resonator, one end of which is immersed in the fluid under test.
- The more viscous the fluid, the higher the mechanical damping of the resonator. By measuring the damping, the product of viscosity and density may be calculated by rheonics’ proprietary algorithms.
- The resonator is both excited and sensed by means of an electromagnetic transducer mounted in the sensor’s body.
- Damping is measured by the rheonics patented sensing and evaluation electronics and stable, high accuracy and repeatable readings are obtained based on rheonics’ proven gated phase-locked loop technology.
Sophisticated, patented 3rd generation electronics drive these sensors and evaluate their response. Ultra-fast and robust electronics, combined with comprehensive computational models, make SRDs one of the fastest and most accurate in the industry. SRD gives real time, accurate viscosity measurements every second and not hardly affected by flow variations!
