DatasheetDynisco PT375 Flush Diaphragm High Pressure Transducer
The Dynisco PT375 is a high-pressure transducer with a flush diaphragm for applications requiring a zero-volume pressure port, fast response time and stringent cleanability standards. The metal-to-metal high-pressure seal enables reliable pressure measurement in demanding processes.
The sensor is especially suitable for slurries, viscous liquids and other media that can be homogenized. Its flush design helps reduce dead volume and minimizes product buildup. The PT375 provides a 3 mV/V output signal, internal 80% shunt calibration and a robust construction with an Inconel 718 pressure fitting.
