DatasheetDynisco Dyn-X-V Melt Pressure Sensors
The Dynisco Dyn-X-V Series includes melt pressure transmitters for general pressure measurement tasks in plastics processing. The sensors are designed for applications requiring simple installation, reliable measurements and good repeatability. With an industry-standard 0…10 VDC output signal, the transmitters can be used directly with PLCs, control systems and common readout instruments.
The Dyn-X-V pressure transmitters offer an accuracy of ±1.0 % FSO combined error, including linearity, repeatability and hysteresis. Zero and span are adjustable via potentiometers, allowing the sensor to be adapted to the respective process conditions. The standard wetted parts are made of DyMax® coated 15-5 PH stainless steel and support reliable pressure measurement in melt applications.
The series is available for pressure ranges from 0…500 psi to 0…10,000 psi. The sensors feature a four-arm bonded foil Wheatstone bridge strain gauge, internal 80 % shunt calibration and a 1/2-20 UNF process thread for installation in standard transducer mounting holes. Optional thermocouple or RTD configurations are available to provide melt temperature measurement in addition to pressure measurement.
