Vorrichtung und Verfahren zum Messen einer Messgroesse bei einem Kunststoff-Spritzgiessverfahren

Sensors, esp. thermocouples for use during plastic injection moulding - are fitted in pairs spaced slightly apart to provide signals esp. for evaluation by a neural network on flow velocities and variations with time.

A measurement is made of a property during plastic injection moulding, e.g. the temperature of a molten plastic (4), by using at least two sensors (6,7) which are spaced some distance apart. USE - Improved temperature sensing method in the confined space available in an injection moulding tool. ADVANTAGE - Twin sensors provide additional information and give greater accuracy.
