Main features

Strain gauge type melt pressure sensor can be directly connected

Our melt pressure sensors can be directly connected for pressure control.

Fast sampling time of 0.025 second

Feedback control with 0.025 second sampling time enables controlling a fast changing process. nPID and other parameters can be set in the unit of 1/100 seconds

Pressure and temperature control can be performed on a single controller

2-channel control is possible on a single unit

Direct access keys

Switching between Auto/Manual, Remote/Local, Run/Stop is quick using direct access keys.
※Direct access keys can be disabled to prevent accidental key operation.
