RHOTEC is a highly precise density sensor for determination of densities and concentrations (e. g. of milk fat, acids or caustics). The sensor can be used for instance for phase detection and for concentration measurement in extraction.
The density sensor RHOTEC continuously measures the density of liquids according to the oscillating U-tube principle. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and maintenance-free. For density measurement the liquid flows through a thin U-shaped tube inside the sensor. Using electromagnets, the tube is excited to oscillate at the resonant frequency. At the same time, an integrated reference oscillator measures the oscillation characteristics. Even the smallest changes in fluid density have an impact on the detected signal and are identified with highest precision. As a specific property of each liquid, the correlation between concentration and density can be described by a mathematical polynomial. With decades of experience and our own laboratory facilities, Centec know the polynomials for a large number of products. Any temperature drifts of the measured signal are automatically compensated for by an internal Pt1000 sensor. RHOTEC can display liquid density and solution concentration in various units.
