Resonant sensing devices and methods
Abstract
Abstract IN ORDER TO DETERMINE THE SURFACE PROPERTIES OF A TEST PIECE A FIXED STATIC FORCE IS APPLIED TO A MECHANICAL RESONATING MEANS FOR HOLDING THE LATTER IN STEADY CONTACT WITH THE TEST PIECE AT A CONTACT SURFACE SHAPED TO PROVIDE INCREASING AREAS OF CONTACT WITH INCREASING PENETRATION THEREOF INTO THE TEST PIECE SURFACE, THE MECHANICAL RESONATING MEANS IS VIBRATED AT A FIXED FREQUENCY AND, WHILE BEING THUS HELD IN STEADY CONTACT WITH THE TEST PIECE AND VIBRATED, A CHARACTERISTIC OR PARAMETER OF THE MECHANICAL RESONATING MEANS WHICH DETERMINES ITS RESONANCE FREQUENCY IS VARIED TO ACHIEVE ITS RESONANCE AT THE FIXED FREQUENCY OF VIBRATION, WITH THE VARIATION OF SUCH CHARACTERISTIC OR PARAMETER REQUIRED TO ACHIEVE RESONANCE BEING MEASURED AS AN INDICATION OF THE SURFACE PROPERTIES, SUCH AS HARDNESS, OF THE TEST PIECE.
