Abstract

A measuring device for an injection molding system for ascertaining a batch-specific characteristic number of a plasticized plastic includes a flow channel which is situated between a plasticizing unit of an injection molding machine and an injection molding tool, a first pressure sensor and a second pressure sensor and a first temperature sensor and a second temperature sensor being situated along the flow channel. The flow channel has a taper between the first pressure sensor and the second pressure sensor.
