About this product
The units are vacuum-resistant.

Function

The pressure sensor displays the current system pressure. It
generates output signals according to the operating mode and the
parameter setting.
It moreover provides the process data via IO-Link.
The pressure sensor is designed for bidirectional communication. So,
the following options are provided:
• Remote display: Reading and displaying the current system pressure
• Remote parameter setting: Reading and changing current parameter
settings
• OI-Link parameter setting
OUT1 (pin 4)
OUT2 (pin 2)

5.2.1 Switching function

OUT1 changes its switching state if it is above or below the set
switching limits (SP1, rP1). The following switching functions can be
selected:
• Hysteresis function / normally open: [ou1 = [Hno] (see Fig. 1).
• Hysteresis function / normally closed: [ou1] = [Hnc] (see Fig. 1).
• First the set point (SP1) is to be determined, then the reset point
(rP1).
The hysteresis thus defined remains, even if SP1 is changed again.
• Window function / normally open: [ou1] = [Fno] (see Fig. 2).
• Window function / normally closed: [ou1] = [Fnc] (see Fig. 2).
• The width of the window can be set by means of the difference
between FH1 and FL1. FH1 = upper value, FL1 = lower value.
