Siemens Process Instrumentation High End Pressure Transmitter SITRANS P500

Overview SITRANS P500 series pressure transmitters are digital pressure transmitters featuring extensive user-friendliness and which fulfill the most stringent demands of accuracy, long-term stability, speed and lots more. Their extensive functionality allows you to set the pressure transmitter specifically to meet the requirements of your application. Despite their many settings options, operation on-site is easy. A multi-lingual menu with clear text instructions guides you through the process. There are also help texts available. The innovative EDD with integrated QuickStart assistance is also quick and easy to parameterize by computer over the HART protocol. Extensive diagnostic functions, e. g. slave pointer for pressure and temperature, or limit value indicator, make sure you always have the process under control. You can also display additional process values in measurement mode such as temperature or static pressure. The simultaneous display of volume is also easy. SITRANS P500 series pressure transmitters can be parameterized to measure: Differential pressure Level Volume Mass volume flow Mass flow Benefits High measuring accuracy Very fast response time Extremely good long-term stability High reliability even under extreme chemical and mechanical loads For aggressive and non-aggressive gases, vapors and liquids Extensive diagnosis and simulation functions which can be used both on site as well as via HART. Optional separate replacement of measuring cell and electronics without recalibration. Extremely low conformity error values Fully adjustable spans of 1.25 to 1250 mbar (0.5 to 500 inH2O) Extremely good total performance and conformity error values with no loss of performance up to a turndown of 10 guaranteed. Additional integrated sensor for static pressure Parameterization via on-site control keys or HART Short process flanges nable space-saving installation. Application SITRANS P500 series pressure transmitters can be used in industrial areas with extreme chemical and mechanical loads. Electromagnetic compatibility in the range 10 kHz to 1 GHz makes them suitable for locations with high electromagnetic emissions. Pressure transmitters with type of protection "Intrinsic safety" and "Flameproof enclosure" may be installed within potentially explosive atmospheres (zone 1) or in zone 0. The pressure transmitter comes with a CE-declaration of conformity and fulfils the corresponding unified European directives (ATEX). Pressure transmitters with the type of protection "Intrinsic safety" for use in zone 0 may be operated with power supply units of category "ia" and "ib". By fitting a new measuring cell, it is possible to work with media temperatures of -40 to 125 °C (-40 to +257 °F) without the use of a remote seal. The transmitters can be equipped with various designs of remote seals for special applications such as the measurement of highly viscous substances. The pressure transmitter can be fully parameterized locally via the three operating keys and externally via HART. Pressure transmitters for differential pressure and flow Measured variables: Differential pressure Small positive or negative pressure Flow q ~ √δp (together with a primary differential pressure device (see Chapter "Flow Meters")) Span (infinitely adjustable) for SITRANS P500 HART: 1.25 to 1250 mbar (0.5 to 500 H2O) Pressure transmitters for level Measured variable: Level of aggressive and non-aggressive liquids in open and closed vessels. Span (infinitely adjustable) for SITRANS P500: 1.25 to 1250 mbar (0.5 to 500 H2O) Nominal diameter of the mounting flange DN 50 / PN 40 DN 80 / PN 40 DN 100/ PN 16, PN 40 2 inch/class 150, class 300 3 inch/class 150, class 300 4 inch/ class 150, class 300 customized special version In the case of level measurements in open containers, the low-pressure connection of the measuring cell remains open (measurement "compared to atmospheric"). In the case of measurements in closed containers, the lower-pressure connection has to be connected to the container in order to compensate the static pressure. The wetted parts are made from a variety of materials, depending on the degree of corrosion resistance required.
