Pressure transmitter
Type DST P40I
For use in corrosive industrial environments such as desalination systems, sea water cooling, waste water
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.
Features
