Endress+Hauser Deltapilot M wet environment pressure transmitter

The Deltapilot M pressure transmitter for level measurement of liquids is specifically designed for wet environments as found outdoors or in hygienic indoor applications.

Wet environments are present in all industries where regular process washdowns or aseptic cleaning procedures are required. In cold media applications, like breweries and dairies, condensation occurs on all surfaces in contact with both the cold media and the external environment.

The ‘condensation tight’ pressure sensor technology, called Contite, in the sensor design allows for the compensation of atmospheric pressure, while preventing the ingress of moisture due either to plant maintenance or condensation.

The Deltapilot M (FMB50) incorporates an integrated temperature sensor at the process connection of the Contite sensor, which compensates for rapidly changing process temperatures, which causes inaccuracies with conventional oil-filled diaphragm seal sensors.

High-pressure washdowns and flooding have no detrimental impact due to the dual IP66 and IP68 rating of the stainless steel housing, and the Gore-tex breather filter that allows the housing to ‘breathe’ without moisture ingress.

The FMB50 is available with the 4-20 mA HART, FOUNDATION Fieldbus, and Profibus PA protocols. For hygienic applications, Deltapilot M has the necessary approvals such as FDA listed materials, surface roughness Ra<0.38, and 3.1B certification.

Rod, rope and compact versions provide the option to mount from the top, side or bottom of the vessel. Covering level measuring ranges from 10 mbar to 10 bar, the sensor also can sustain pressure shocks of up to 4 MPa.
