▷ Product Character


The SITRANS P Series DSIII is a precision digital transmitter for absolute differential pressure has extensive diagnostics and simulation functions.



Thestandard unit already delivers excellent, TUV-approved reliability through its evaluation abilities.



The maximum working pressure is 420bar.



▷ Product Advantage


* Extensive diagnostics and simulation functions

* Accuracy <= 0,075%

* Long-Term Stability <= 0,25% / 60 months

* Wetted parts in stainless steel 1.4571, Hastelloy, Gold

* Measuring range 1mbar to 30bar

* Wide range of certification and approval e.g. ATEX EEx ia/ib, EEx d, Dust protection, FM, CSA



Settings can be made on-site by push buttons and, through the HART protocol or Profibus PA, Profile 3.0.



▷ Application


* Measured variables:

　- absolute Differential pressure

　- Small positive or negative pressure

　- Flow q ~ √?p (together with a primary differential pressure device (see Chapter "Flow Meters"))

* Span (infinitely adjustable) for DS III HART: 1 mbar ... 30 bar (0.0145 ... 435 psi)

* Nominal measuring range for DS III PA and FF: 20 mbar ... 30 bar (0.29 ... 435 psi)
