DatasheetDynisco PT130, PT140, PT150 and PT160 Hydraulic Pressure Sensors
The Dynisco PT130, PT140, PT150 and PT160 series are designed to measure hydraulic pressure on injection molding machines. The sensors withstand cyclic pressure loads and provide reliable measurements under demanding operating conditions.
Typical applications include monitoring injection and clamp pressure as well as detecting hydraulic pressure profile variations during the injection and feeding stages of the molding process. The compact, rugged and all-welded stainless steel construction is ideal for industrial use in high-temperature processes.
