ABSTRACT:
Apparatus is provided for sensing the pressure and temperature of fluid within a cavity of a block, such as hot plastic that flows into a mold cavity. The apparatus includes a piston (30) lying closely but slideably within a bore that extends from the cavity in the block. The outer end of the piston is coupled through a beam structure (36), in a shape of a diaphragm, to a rigid support (40). A strain gauge (44) mounted on the diaphragm senses piston deflection which is proportional to the pressure of fluid in the cavity. A highly heat conductive rod (80) extends through a hole in the middle of the piston, the rod having an inner end (84) that is flush with the piston and the rod having an outer end (86) joined at a thermocouple joint (92), so the temperature of the rod is sensed by the thermocouple to thereby sense the temperature of material in the cavity.
