Abstract
A pressure measuring device for an injection molding machine having a plasticizing screw operated by a rotary drive and an injection drive includes a load detector having a deformation zone which forms part of a transmission member of the injection drive and is of reduced cross section, and a sensor. The deformation zone elastically deforms in response to a driving force acting on the transmission member, with the sensor measuring a change in shape of the deformation zone.
