Abstract
A transducer for measuring the pressure characteristics of elastic material to be injection moulded includes a transducing element contained within a sleeve member mounted in an injection moulding device. An end of the sleeve member adjacent the material whose pressure characteristics are to be measured contains a pressure transmitting element for transmitting the pressure characteristics of the injection moulded material to the transducing element. Support and guiding structure is provided for supporting the transducing and pressure transmitting elements in the sleeve member, and for maintaining a uniform spacing of the pressure transmitting element from the internal wall of the sleeve member.
