DatasheetDynisco MDT4X0 Melt Pressure Transmitters with Voltage Output
The Dynisco MDT4X0 melt pressure transmitter series is based on proven Dynisco MDA technology and is designed for precise process pressure measurement in high-temperature applications. The integrated amplifier converts the applied process pressure into a proportional voltage output signal.
The MDT4X0 series features a rigid stem between the diaphragm and housing as well as a smooth, flush diaphragm. This makes the transmitter particularly suitable for applications in plastics and polymer processing. The integrated electronic calibration function supports simple commissioning and verification of the measuring system.
