26″
, 27″
), the pressure chamber housing comprises;
a pressure cavity (4′
, 4″
) inside the pressure chamber housing, and at least one first port (5′
, 5″
) for inlet and/or outlet of fluid to the pressure cavity (4′
, 4″
),a bellows (6′
, 6″
) defining an inner volume (7′
, 7″
) inside the pressure cavity (4′
, 4″
), and wherein the inner volume (7′
, 7″
) of the bellows is in fluid communication with the connection port (3′
, 3″
) such that drive fluid in the form of pressurized hydraulic fluid from the dual acting pressure boosting liquid partition device (2) is allowed to enter and exit the inner volume (7′
, 7″
) of the bellows (6′
, 6″
),wherein the pressure cavity (4′
, 4″
) has a center axis (C) with an axial length (L′
;
L″
) defined by the distance between the connection port (3′
, 3″
) and the first port (5′
, 5″
), and wherein the bellows (6′

, L″
) of the pressure cavity (4′
, 4″
),wherein the bellows (6′
, 6″
) comprises a guiding system (9′
, 9″
) which comprises a guide (9′
, 9″
), the guide (9′
, 9″
) being connected to a lower part of the bellows (6′
, 6″
) and is configured to be guided in the pressure chamber housing forming part of the connection port (3′
, 3″
, wherein the guide (9′
, 9″
) is coinciding with, or being parallel to, a center axis (C′
, C″
) of the pressure cavity (4′
, 4″
), and wherein the bellows (6′
, 6″
) expands and retracts axially in a longitudinal direction along the center axis (C′
, C″
),and wherein the pressure transfer device further comprises a bellows position sensor (12′
, 12″
) monitoring position of the bellows (6′
, 6″
).
