Dynisco PT46X4 Pressure Sensors with SIL2
The Dynisco PT46X4 series is designed for general-purpose melt pressure measurement and is suitable for applications requiring simple installation, repeatability and reliability. The industrial 4–20 mA output signal is designed for connection to DCS and PLC control systems.
The sensors feature adjustable zero and span potentiometers as well as internal 80% shunt calibration. Rezeroing can be performed locally via the zero potentiometer or remotely by shorting two pins. The PT46X4 series meets Performance Level “c” according to EN ISO 13849-1 and Safety Integrity Level 2 and can be used with an optional safety relay as part of a safe machine solution.
