Abstract
Two magnetostriction-based methods for measuring atmospheric pressure are p resented. Each technique correlates changes in pressure with the characteri stic resonant frequency of a magnetoelastic magnetostrictive thick-film sen sor. In each case the sensor is monitored remotely, using an adjacently loc ated pickup coil, without the use of physical connections to the sensor. (C ) 1999 American Institute of Physics.
