Viscosity

Measuring the viscosity of a medium with the Steuma viscositymeter
ViscoTron process viscometers measure the viscosity of liquids continually and precisely in-line. ViscoTron sensors have virtually no moving parts and are maintenance free. Torsional oscillation viscometers are surface loading devices. These devices measure the viscosity at the interface between the liquid and the solid surface.
The sensor bulb twists back and forth at the sensors natural resonance. The drive shaft is welded to the sensor and moves the sensor, resulting in a micron size motion at the sensor surface. The
compliant sheath, which is also welded to the sensor and the opposing static plane, acts as a spring for the resonance. This completely welded construction hermetically seals the internal mechanism from the
process and provides high integrity of the sensor. The vibration on the sensor surface can barely be felt.

ViscoTron sensors utilize a constant amplitude torsional oscillation principle to measure the viscosity. The power required to achieve the constant amplitude is a measure for the viscosity. This technology allows for the large range ability of our ViscoTron systems.
