DatasheetDynisco EMT4XX 2 Intrinsically Safe Melt Pressure Transmitter with Temperature Measurement
The Dynisco EMT4XX 2 series is based on proven TDT technology and is specifically designed for pressure measurement in hazardous areas. The integrated two-wire amplifier converts the process pressure into a noise-immune 4–20 mA output signal, ensuring reliable signal transmission even over long distances.
An integrated thermocouple allows simultaneous temperature measurement directly at the process medium. The flexible connection between the sensing stem and electronics housing improves thermal isolation and simplifies installation. The series features a flush diaphragm, integrated electronic calibration functionality and ATEX certification for use in potentially explosive atmospheres.
