Abstract
The present invention relates to a retrievable pressure sensor for in situ measurement of pressure in a process fluid in a pipe/chamber. The pressure sensor comprising a pressure-transferring device and an outer sensor part having a pressure sensing element attached at a distance from the pipe/chamber where the pressure is to be measured. The pressure-transferring device comprises a first device for sealing attachment in an opening in a wall of the pipe/chamber where the pressure is to be measured, and has a first separation diaphragm for separating between the process fluid and the pressure-transferring fluid. The pressure-transferring device further comprises a second device for attachment at a distance from the pipe/chamber where the pressure is to be measured. The pressure-transferring device comprises a first cavity with a pressure-transferring fluid, wherein the first cavity comprising a capillary tube for pressure transferring connection between the first device and the second device.
