Danfoss DST P40I Titanium Pressure Transmitter for Harsh Environments

Danfoss DST P40I Titanium Pressure Transmitter for Harsh Environments
DST P40I

Danfoss Sensor Technology (DST) P40I pressure transmitter has been designed for use in corrosive industrial environments such as desalination systems, sea water cooling, waste water, etc..

The enclosure of the pressure transmitter is machined out from a single piece of Titanium to eliminate any structural weaknesses. Titanium is exceptionally resistant to a broad range of acids and alkalis, as well as Sodium Chloride and polluted waters. Titanium’s corrosion resistance together with its low density, high strength and erosion resistance, make this pressure transmitter ideal for numerous chemical processing and marine uses.

The pressure sensing element is made from ceramic Al2O3 96% which has excellent chemical immunity and is suitable for nearly all aggressive media. The pressure transmitter works following the piezo resistive principle and the Wheatstone bridge is screen printed directly on one side of the ceramic diaphragm by means of Thick Film technology.
