Functions - Siemens SITRANS FC430 Operating Instructions Manual

Description
3.1 Design
The sensors are available in AISI 316L stainless steel and Hastelloy C22. The enclosure is
made of AISI 304 stainless steel which has a pressure rating of 20 bar (290 psi) for DN 15 to
DN 50 and 17 bar (247 psi) for DN 80. The burst pressure for all sizes is in excess of 160 bar.
The sensor enclosure can be equipped with a pressure guard or flushed with dry inert gas at
the threaded ports for non-hazardous applications only.
Note
Ex certification requires that the threaded ports always remain closed.
In the remote configuration, the sensor front end (DSL) is available in an painted aluminum,
with an ingress protection grade of IP67/NEMA 4X. For communication and power supply a 4-
wire connection can be made via M12 plug and socket or cable gland/conduit entry for cable
termination.

Transmitter design
The transmitter reads the primary values from the sensor and calculates derived values. It
provides up to four configurable I/Os. On channel 1, HART communication, PROFIBUS DP,
PROFIBUS PA or Modbus RTU RS485 is possible. On channel 2,3,4 each I/O can be
individually configured. A local display (human machine interface - HMI) is available, which
consists of a display and four buttons for user interaction. The transmitter adds functionalities
such as Standard volume flow, fractions, totalizers, dosing, access control, diagnostics,
configuration and logging.
The transmitter has a modular design with discrete, replaceable electronic modules and
connection boards to maintain separation between functions and facilitate field service. All
modules are fully traceable and their provenance is included in the transmitter setup.
