2. Function / 3. Safety
2. Function
F-20: Pressure connection with internal diaphragm (standard version).
F-21: Pressure connection with flush diaphragm for highly viscous or solids entrained media which might clog the
pressure port.
The pressure prevailing within the application is transformed into a standardised electrical signal through the deflection
of the diaphragm, which acts on the sensor element with the power supply fed to the transmitter. This electric signal
changes in proportion to the pressure and can be evaluated correspondingly.
3. Safety

3.1 Explanation of symbols

WARNING!
... indicates a potentially dangerous situation that can result in serious injury or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries or damage to equipment or
the environment, if not avoided.
WARNING!
... indicates a potentially dangerous situation that can result in burns, caused by hot surfaces or liquids,
if not avoided.
Information
... points out useful tips, recommendations and information for efficient and trouble-free operation.

3.2 Intended use

The pressure transmitter is used for measuring pressure. The measured pressure is output as an electrical signal.
Only use the pressure transmitter in applications that lie within its technical performance limits (e.g. max. ambient
temperature, material compatibility, ...).
