Abstract
The present invention concerns a beverage preparation machine () comprising: a reservoir () for a fluid, a brewing head () adapted to receive at least one ingredient capsule () comprising at least one beverage preparation ingredient (), a pump () for pumping a predetermined volume of said fluid from said reservoir () to said brewing head (), such that said fluid can be injected into said capsule (), when said capsule () is received by said brewing head (), to mix with said ingredient () under pressure and produce a predetermined volume of beverage, wherein the reservoir (), the pump (), and an inserted ingredient capsule () in use are in fluidic communication and form a fluid system (), and wherein the beverage preparation machine () further comprises a pressure sensor () adapted to measure internal pressure (P) within an ingredient capsule () inserted inside said brewing head (), and a locking mechanism () adapted to prevent disconnection of the inserted ingredient capsule () from the fluid system () if the measured internal pressure (P) exceeds a predetermined threshold pressure value (Pt).
