  • robust stainless steel housing (safety housing)
  • high-precision measurements with integrated transducer
  • mechanical, power-independent local display

For pressure measurements with a power-independent local display in combination with an electrical output signal.

The DMU 13 pressure transducers consist of a mechanical Bourdon tube measuring element and a piezo-resistive stainless steel measuring cell. The Bourdon tube measuring element is used to provide an easy-to-read analogue local display. The display is power-independent. Due to the integrated pressure transducer, high-precision measurement in parallel is possible. A standardised current output is available for signal transmission and recording of measured data. The robust stainless steel housing has a solid baffle wall and blow out (safety housing).
