DatasheetDynisco DYN-X Series
The Dynisco DYN-X Series includes economical melt pressure sensors for general pressure measurement tasks in plastics processing. The sensors are designed for applications requiring simple installation, reliable measurements and good repeatability. As a value-priced series, the DYN-X provides an industry-standard 3.33 mV/V output signal and is designed to work with most common pressure indicators and readout instruments.
The DYN-X pressure sensors offer an accuracy of ±1.0 % FSO combined error, including linearity, repeatability and hysteresis. The standard wetted parts are made of DyMax® coated 15-5 PH stainless steel. This supports superior abrasion resistance and contributes to stable and repeatable pressure measurements.
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.
