RHOTEC - Measurement of density & concentration (2-component mixture)

 The RHOTEC density sensor continuously measures the density of liquids using the oscillating oscillator principle. The instrument is designed for applications requiring maximum sensitivity and the highest accuracy. It is easy to use and maintenance-free. For density measurement, the liquid flows through a thin, U-shaped tube inside the sensor. Electromagnets excite the tube to oscillate at its resonant frequency. Simultaneously, an internal reference oscillator measures the oscillation behavior. Even the smallest changes in the liquid's density affect the measured signal and are detected with the highest precision. As a specific property of every liquid, the relationship between concentration and density can be described by a mathematical polynomial. With decades of experience and our own laboratory facilities, Centec knows the polynomials for a large number of products. Temperature drifts of the measurement signal are automatically compensated by an internal Pt1000 sensor. RHOTEC can display liquid density and solution concentration in various units.
