1. A pressure release valve for ventilation comprising:
a main body having a first gas chamber, a second gas chamber, at least an inlet duct for supplying a gas to the first gas chamber and an outlet duct for releasing the gas from the first gas chamber, whereby said outlet duct and said inlet duct form said first gas chamber,
wherein the first gas chamber and the second gas chamber are connected at least by a first passage opening,
a proportional valve for temporally sealing the first gas chamber from the second gas chamber, while the second gas chamber comprises at least a second passage opening for releasing the gas from the second gas chamber, and
the second gas chamber comprises a port for connecting a pressure measurement apparatus for measuring the gas pressure in the second gas chamber.
