Stress wave sensor

A stress wave sensor in communication with an electronic assembly used for stress wave analysis, said electronic assembly including a band pass filter, said sensor comprising:

• a transducing element generating a primary resonant frequency approximately between 35 KHz to 40 KHz;
• a charge converter in communication with said transducing element;
• and
• a high pass filter in communication with said charge converter for attenuating received signals that fall below a frequency of approximately 20 KHz;
• wherein said sensor having a resonant gain of approximately 30 db at its primary resonant frequency to allow for selective amplification of stress waves;
• wherein said sensor having a resonant output of a specific amplitude, said resonant output decaying to half amplitude by a predetermined number of cycles.

A stress wave sensor in communication with an electronic assembly, said sensor comprising:

• a transducing element generating a primary resonant frequency;
• a charge converter in communication with said transducing element;
• and
• a high pass filter in communication with said charge converter for attenuating received signals that fall below a selected frequency;
• wherein said sensor having a resonant gain of approximately 30 db at its primary resonant frequency and a resonant output of a specific amplitude, said resonant output decaying to approximately half amplitude by a predetermined number of cycles.

A stress wave senor in communication with an electronic assembly, said senor comprising;

• a transducing element generating a primary resonant frequency;
• a charge converter in communication with said transducing element;
• and
• a high pass or band pass filter in communication with said charge converter for attenuating received signals that fall below a selected frequency prior to any amplification of the received signals to prevent saturation of any signal conditioning amplification outside of the sensor;
• wherein the received signals includes a low frequency component and a high frequency component;
• wherein said high pass or band pass filter attenuates said low frequency component so that the high frequency component represents a significant percentage of the filtered signal prior to any subsequent amplification outside of the sensor.
