  • DMU 04 CP/MR for hygienic processes
  • small temperature error
  • Options: Ex, field housing or high temperature version (up to 300 °C) and SIL 2

For applications requiring hygienic process connections, materials or processing, especially food technology, pharmaceutical and biotechnology applications.

Pressure transducers convert physical pressure into an electrical signal proportional to the pressure. DMU 4 is equipped with an oil-filled piezo-resistive silicon measuring cell. DMU 04 has safety integrity level SIL 2 (IEC 61508/61511).
