RHOTEC is a high-precision density sensor for the continuous measurement of density and concentration in two-component mixtures . Designed for applications requiring maximum sensitivity and very high measurement accuracy – with simple operation and maintenance-free performance .


 Application
 RHOTEC is suitable for determining densities and concentrations , e.g. in:
 
 
 Acids
 
 
 Lye
 
 
 Emulsions
 
 
 solvents

 Typical use cases:
 
 
 Phase detection
 
 
 Monitoring of crystallization processes



 Measuring principle (flexural oscillator)
 
 
 The product flows through a thin, U-shaped tube in the sensor.
 
 
 Electromagnets stimulate the tube to vibrate at its resonant frequency .
 
 
 An internal reference oscillator records the vibration behavior.
 
 
 Even the smallest changes in density affect the signal and are detected precisely.



 From density to concentration
 
 
 The relationship between density and concentration can be represented in a product-specific way using a mathematical polynomial .
 
 
 RHOTEC can display density and concentration in various units.



 Temperature compensation
 
 
 Temperature drifts are automatically compensated via an internal Pt1000 sensor .
