304), 1.4308 (ASTM CF8). The maximum permissible operating pressure is determined by the
respective process connection, considering the process temperature.
Note
Ex certification requires that the threaded ports always remain closed.
In the remote version, the DSL is available in a painted aluminum with an ingress protection
grade of IP67/NEMA 4X. For communication and supply voltage a 4-wire connection can be
made via M12 plug and socket or cable gland/conduit entry for cable termination.

3.2.3 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 RS-485 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.
