N-11: Pressure connection with flush diaphragm (non-incendive) for highly viscous or
solids entrained media which might clog the pressure port.
GB
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 transmitter. This electric signal changes in proportion to the pressure
and can be evaluated correspondingly.

Funktion
Mittels Sensorelement und unter Zuführung von Hilfsenergie wird über die Verformung einer
Membran der anstehende Druck in Ihrer Anwendung in ein verstärktes standardisiertes elektrisches Signal umgewandelt. Dieses elektrische Signal verändert sich proportional zum Druck
und kann entsprechend ausgewertet werden.
5. Zu Ihrer Sicherheit
