COURSES

Ravenfield run a variety of short courses tailored to the need of our customers. If there is a viscosity related course that you need and cannot find, contact us and we will do our best to provide it. All our courses can be run at a venue convenient for you and your colleagues.

HTHS Operator Training Course

This is our most frequently provided course and is recommended for all operators of any model of Ravenfield HTHS viscometer. To cover all the relevant details and have time to provide “hands-on” experience this is a two day course. Topics covered include:

* Laboratory requirements
* Safety considerations
* Inspection of goods on receipt
* Initial installation or relocation
* Shear rate calibration
* Torque calibration
* Preparing the calibration graph

* Dealing with problems
* Temperature measurement and control
* Simple service techniques for those in hard to reach destinations
* Hands-on for operators
* Q & A session
* Some other Ravenfield technologies

More advanced techniques:

* Verification of instrument linearity
* Calibration of temperature sensors (necessary for ISO 9000)
* Selecting non-standard operating conditions
* Limits on measurements.
* The thermodynamics of HTHS measurement.
* Generating flow-curves
* Q & A session

An Introduction to Viscosity

This is the latest addition to our range of courses. It aims to give an understanding of:-

* The meaning of viscosity, shear stress, shear rate, Newtonian & non-Newtonian behaviour, apparent viscosity, Reynolds number
* Rheological behaviour, e.g. temporary structure, yield stress, viscoelasticity
* Various geometrical systems, their assumptions and limitations
* Why failures of measurement occur
* The significance of Constitutive equations
* What to do to get repeatable results
* What is meant by statistical control and how to practice it
* Repeatability, Reproducibility, Bias, Precision
