摘要：
Device for measurement of fluid pressure by means of an arrangement of strain gauges (5) provided on a sensor head (1) arranged on an item (2) arranged to be exposed to a pressurized fluid (4) against an external sensor head surface (1b'), where the sensor head (1) comprises a fastening portion (1a) attached to the item (2), and a centre portion (1b) connected to the fastening portion by means of at least one flexible connecting element (1c), the arrangement of strain gauges (5) is attached to the centre portion (1b) of the sensor head (1) on an internal assembly surface (1b'') arranged in close proximity to a contact face (2d) on an end stopper (2b) which in an active condition encircles the arrangement of strain gauges (5), and the assembly surface (1b'') is inexposable for the pressurized fluid (4).
