DatenblattDynisco PT4674 Melt Pressure Transmitter
The Dynisco PT4674 is a highly reliable melt pressure transmitter designed for plastic processing applications where installation space is limited. The transmitter provides a standardized 4–20 mA output signal for direct connection to DCS, PLC and process control systems.
The sensor features a 1/2-20 UNF process connection, adjustable zero and span settings, and an integrated 80% shunt calibration function. Its rugged construction with DyMax™ coated stainless steel wetted parts ensures excellent resistance to abrasive media and long-term measurement stability.
