Abstract
A downhole sensor system for measuring a pressure of a fluid downhole in a well, includes a well tubular structure having an inside and being arranged in a borehole with a wall and an annulus defined between the well tubular structure and the wall of the borehole, a sensor unit having a pressure unit sensor and being arranged in connection with the well tubular structure, the pressure unit sensor being adapted to measure a pressure of the fluid in the inside of the well tubular structure and/or in the annulus. The sensor unit further has a power supply and a communication module, a downhole tool with a power supply and a communication module for communication with the sensor unit. The downhole tool further comprises a pressure tool sensor adapted to measure a pressure of the fluid inside the well tubular structure substantially opposite the pressure unit sensor for comparison with the pressure measured by the pressure unit sensor.
