4. Function / 5. For your safety
Function
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 sensor. This electric signal changes in proportion to the pressure and
can be evaluated correspondingly.
