Centec Rhotec

Concentration and quantity

Introducing RHOTEC, a precision density sensor crafted for determining densities and concentrations of various substances like acids, caustics, emulsions, or solvents. This sensor's accuracy is invaluable for tasks such as phase detection and monitoring crystallization processes with utmost precision

Description

Here's how the RHOTEC sensor operates: The liquid under examination flows through a slender U-shaped tube within the sensor. Using electromagnets, the tube is stimulated to oscillate at its resonant frequency. Simultaneously, an integrated reference oscillator meticulously records the oscillation characteristics. Even the slightest alterations in fluid density are detected with exceptional precision and have a discernible impact on the recorded signal.
