A pressure measurement system comprising: a pressure channel system filled with a pressure fluid; a pressure sensor connected to the pressure channel system and providing a pressure measurement of a process in a process containment based on a pressure of the pressure fluid, the pressure channel system being connected to the process containment via a first channel; a first diaphragm seal arranged between the process and the first channel and being seatable to a seat located opposite to a side of the diaphragm facing the process; and a second diaphragm seal arranged in a second channel that is fluidically connected with the first channel, and an operating member configured to move the second diaphragm seal between a first position and a second position thereby changing a fluid volume in pressure channel system such that the first diaphragm seal is moved between an active position in which the pressure sensor obtains a pressure reading of the process in the process containment, and a parked position in which the first diaphragm seal is held against the seat formed between the first channel and the process containment, the seat having a majority of its area shaped corresponding to a shape of the first diaphragm seal, characterized in that said operating member is a cylinder assembly which, based upon an activation, moves the second diaphragm seal from the second position to the first position or from the first position to the second position, wherein the cylinder assembly includes a piston and a piston rod, the piston rod connecting the piston to the second diaphragm seal, and wherein the piston is moveable within the cylinder assembly to be in the first position or the second position. a pressure channel system filled with a pressure fluid; a pressure sensor connected to the pressure channel system and providing a pressure measurement of a process in a process containment based on a pressure of the pressure fluid, the pressure channel system being connected to the process containment via a first channel; a first diaphragm seal arranged between the process and the first channel and being seatable to a seat located opposite to a side of the diaphragm facing the process; and a second diaphragm seal arranged in a second channel that is fluidically connected with the first channel, and an operating member configured to move the second diaphragm seal between a first position and a second position thereby changing a fluid volume in pressure channel system such that the first diaphragm seal is moved between an active position in which the pressure sensor obtains a pressure reading of the process in the process containment, and a parked position in which the first diaphragm seal is held against the seat formed between the first channel and the process containment, the seat having a majority of its area shaped corresponding to a shape of the first diaphragm seal, characterized in that said operating member is a cylinder assembly which, based upon an activation, moves the second diaphragm seal from the second position to the first position or from the first position to the second position, wherein the cylinder assembly includes a piston and a piston rod, the piston rod connecting the piston to the second diaphragm seal, and wherein the piston is moveable within the cylinder assembly to be in the first position or the second position.
