DatasheetDynisco PT46X6 Pressure Sensors with Voltage Output
The Dynisco PT46X6 series is designed for general-purpose melt pressure measurement in plastics processing and extrusion applications. These sensors provide simple installation, high repeatability and reliable voltage output signals for direct connection to DCS and PLC control systems.
PT46X6 pressure sensors feature adjustable zero and span potentiometers for easy process adaptation. Optional thermocouple or RTD versions are available for simultaneous temperature measurement. The standard 1/2-20 UNF process connection allows easy installation in existing transducer mounting holes.
