Abstract (en)
[origin: EP1111232A2] The device has a pressure line, at least one device for measuring/regulating the pressure in the pressure line with a housing connected to the line and in communication with the line via a housing opening and a piezoelectric element facing the housing opening at one end and supported on the housing at the other. The piezoelectric element has connections for picking up pressure-induced voltages and/or applying voltages to produce dimension changes. The device has a pressure line (12) and at least one device for measuring and/or regulating the pressure in the pressure line, whereby the measurement/regulating device (14) has a housing (16) connected to the pressure line and that communicates with the pressure line via a housing opening (18) and a piezoelectric element (22) facing the housing opening at one end and supported on the housing at the other end. The piezoelectric element has connections via which pressure-induced electrical voltages can be picked up and/or electrical voltages can be applied to produce dimensional changes. Independent claims are also included for the following: a device for measuring and/or regulating the pressure in a pressure line and a method of pressure regulation in a pressure line.
