A new torque and normal thrust measuring system for the Weissenberg rheogoniometer
At Warren Spring Laboratory a new torque and normal thrust measuring system, suitable for fitting to most models of the Weissenberg Rheogoniometer with the exception of the R 17, has been developed. A single piezoelectric crystal device completely replaces the air bearing torsion assembly, and therefore the need for a compressed air supply, and also replaces the servo assisted normal thrust measuring system.
