Quartz Viscometer for Lab Instrumentation and for Process Control

The QVis quartz viscometer from KMB² (Germany) is an instrument for advanced process control and for laboratory instrumentation. The core of this patented measuring system without moving parts is an oscillating quartz (56 kHz pure shear wave torsional transducer) which is dampened by the viscous properties of the surrounding sample. A Pt100 temperature probe is integrated. The measuring range is 1 to 10,000 mPas at –50°C to +300°C and up to 1450 psi. The oscillating quartz provides a self-cleaning effect. The viscometer is available as easy-to-use lab instrument with an unthreaded sensor head (OD: 25 mm). Operation is stand-alone or by PC control. A battery pack is available.

The process type of this instrument (explosion-proof if required) has a 1“ thread sensor module for in-line use, also in fluent media. With its integrated PI controller, the process viscometer allows to actively control the viscosity of oils, paints, coatings, etc. As this instrument uses the same measuring principle in the lab as in the process, it is most suitable for research, development and for quality control, e.g. in production and blending lines.
