Valve assembly and method for calibrating a valve assembly

The device (2-5) has valve housing (17) which bounds valve chamber in which valve member is accommodated for movement between blocking position and release position. Absolute pressure sensor (10) provides pressure signal as function of operating pressure in flow path. Evaluation circuit (16) process...

Beschreibung
Zusammenfassung:	The device (2-5) has valve housing (17) which bounds valve chamber in which valve member is accommodated for movement between blocking position and release position. Absolute pressure sensor (10) provides pressure signal as function of operating pressure in flow path. Evaluation circuit (16) processes pressure signal. Absolute pressure sensor (11) provides another pressure signal as function of reference pressure outside flow path and connected to evaluation circuit that enables differential pressure between pressure signals to be determined. An independent claim is included for a method for calibrating valve assembly.
