Electronic pressure sensor

4 Function
Measuring cell:
•
The system pressure is measured by a ceramic capacitive measuring system.
•
The sealing of the ceramic measuring cell is free of elastomers and thus maintenance-free.
Signal transmission:
•
The unit can be operated in analogue mode and in IO-Link mode. When connected to an IO-Link
master, the unit automatically switches to IO-Link mode. An additional manual switching is not
required.
Analogue mode:
•
Analogue signal measured pressure value 4-20 mA (pin 2).
IO-Link mode (pin 4):
•
Measured pressure value
•
Exceeding or falling below the limits of the measuring range
•
Device status
•
Parameter setting
•
Device diagnostics (events)
4.1 IO-Link
IO-Link is an internationally standardised IO technology (IEC 61131-9) for communicating with
sensors and actuators.
Further information about IO-Link at:
IO-Link offers the following advantages:
•
Noise-immune transmission of several process values.
•
Parameter setting during operation as well as point-to-point at the desk.
•
Device diagnostics (events)
•
Data storage: Automatic new parameter setting in case of replacement.
•
Detection of connected units.
•
Freely definable parameters to identify the units in the plant.

4.2 IO-Link properties of the sensor
4.2.1 Description IO-Link interface
A description of the IO-Link interface can be found at
The sensor provides the internal unit temperature as a readable parameter for diagnostic purposes.
4.2.2 Additional functions via IO-Link
•
Device temperature: the internal temperature of the sensor can be read via the A-cyclic IO-Link
channel.
