Abstract

A free active element bulk-modulus high-pressure transducer equipped with a fiber-optic displacement sensor for radial deformation detection of the active element is presented in this paper. The accuracy of the transducer at pressure ranges up to 100 MPa was estimated at 1.5% of full scale. The developed transducer can be used to measure hydrostatic or variable pressure in electrically conducting and/or in high-viscosity media, is electrically passive and can work safely in explosive environments
