Biaxial Pressure Sensor

Details

• Personal Author:
  Allwes, Richard A.
• Description:
  A pressure sensor (10) is useful for monitoring stress changes and stress fields in a medium (12) having a borehole (14) defined therein. The pressure sensor uses piston assemblies (22, 24, 26) to transmit pressure changes to gages (84) via a fluid in a fluid line (78). The piston assemblies can be spaced apart angularly and longitudinally of the borehole to monitor a plurality of locations (16, 18 and 20), and are angularly movable with respect to each other.
