Abstract

Disclosed herein is a pressure sensitive element (2, 2', 2a, 2b, 2a', 2b') for geothermal applications, comprising: - a shell (4, 4', 4a, 4b, 4a', 4b') enclosing a three-dimensional space, the shell (4, 4', 4a, 4b, 4a', 4b') comprising a wall (6a, 6b, 6a', 6b') having a wall thickness, the wall being made of temperature resistant and elastic material, and - a compressible and/or expandable, pressure-sensitive fluid arranged within the shell (4, 4', 4a, 4b, 4a', 4b'). The shell (4, 4', 4a, 4b, 4a', 4b') is designed to allow expansion or contraction in a first direction (A) upon external pressure change, as seen on a cross sectional plane cut through the shell (4, 4', 4a, 4b, 4a', 4b'). The cross sectional plane is parallel with the first direction (A) and wherein the first direction (A) is determined by a wall thickness of the shell (4, 4', 4a, 4b, 4a', 4b'), which is chosen to be smaller than the wall thickness of the shell (4, 4', 4a, 4b, 4a', 4b') in other parts, at least along a partial length (L) of the wall (6a, 6b, 6a', 6b') in the cross sectional plane.
