DatasheetDynisco MDA410 Pressure Sensor
The Dynisco MDA410 is a melt pressure sensor for non-mercury food and medical extrusion applications. With its special high-temperature NaK fill and Inconel 718 diaphragm, the sensor is suitable for accurate pressure measurement at very high process temperatures up to 540 °C.
The MDA410 Series provides high accuracy, excellent repeatability and reliable measurement performance in demanding extrusion processes. The sensor offers a 3.33 mV/V output signal, internal 80% shunt calibration and is optionally available with a Type J thermocouple.
