DatasheetDynisco MDT4X2 Melt Pressure Transmitters with Voltage Output
The Dynisco MDT4X2 melt pressure transmitter series is based on proven strain gauge technology and is specifically designed for accurate pressure measurement in extrusion, polymer processing and other high-temperature applications. An integrated amplifier converts the pressure signal directly into a proportional voltage output signal, ensuring reliable transmission over long distances.
A flexible capillary connection between the sensing stem and electronics housing improves thermal isolation between the hot process and the electronics. The flush diaphragm design and integrated electronic calibration function simplify installation, commissioning and maintenance. Depending on the model, various voltage output ranges and both 3-wire and 4-wire configurations are available.
