Abstract
A free active element bulk-modulus high-pressure transducer equipped w ith a differential fiber-optic displacement sensor for radial deformat ion detection of the active element is presented in this paper. The ac curacy of the transducer at pressure ranges up to 100 MPa was estimate d at 1.5% of full scale. The developed transducer can be used to measu re hydrostatic or variable pressure in electrically conducting and/or in high-viscosity media, is electrically passive, and can work safely in explosive environments.
