2.1 Overview, diaphragm seal system
2.2 Description
The flush diaphragm at the process connection of the diaphragm seal system transmits
the process pressure via a system fill fluid to the pressure sensor. The model DSSA11SA
diaphragm seal system is available in different versions.

In the basic version, the instrument is fitted with a pressure sensor without a display,
which, depending on the application, can be used either for pressure monitoring or as an
electronic PNP/NPN switch for process control.
With an additional IO-Link interface, the instrument can be programmed flexibly and has
integrated diagnostic functions that monitor the instrument status. In addition, this allows
the digital signal to be configured externally and conveniently at any time.
This version, which has been enhanced with a 360° LED status indication, provides visual
information about the status and enables intuitive and quick error detection and correc-
tion. For maintenance, a blinking function via IO-Link facilitates the clear localisation of a
diaphragm seal system. The blinking function prevents confusion of measuring locations
and accelerates maintenance.
In addition to the IO-Link, the teach function enables a further on-site configuration of the
switch point if a convenient factory setting of the point is not possible.
