Abstract
A downhole closed-loop magnetostrictive sensor includes a magnetic field generating member and a waveguide operatively connected to the magnetic field generating member. At least one of the waveguide and the magnetic field generating member is responsive to a parameter being sensed. A sensor is operatively connected to the waveguide, and a housing includes a chamber enclosing the magnetic field generating member, the waveguide and the sensor. The housing is configured and disposed to withstand a downhole environment.
