## Abstract

A shot peening intensity measurement device has a holder and a test disk formed from a resonant and hardened material. The test disk is held to the holder with a cover that threads onto the holder and clamps the test disk. The holder and test disk form a chamber where a portion of the test disk is unsupported. A measurement device, such as a microphone or other non-contacting device detects vibrations from the test disk when shot or media contacts the test disk.

## Claims

### Claim 1

A shot peening sensor comprising:
a holder having a bottom wall with a sidewall extending therefrom, said sidewall terminating at a top surface to form an open top, said top surface having a disk pocket surface recessed from said top surface, said sidewall having threads;
a test disk having a thickness defined by a distance between an outwardly facing surface and an inwardly facing surface, said distance being greater than a depth of said disk pocket, said test disk and said holder forming a chamber, said test disk having an unsupported area resonating in response to impacts from shot to said outwardly facing surface;
a mounting cover having complimentary threads mating with said threads on said sidewall to clamp said test disk to said holder and overlay said open top, said mounting cover having an aperture to expose a portion of said test disk; and
a microphone spaced from said test disk and being held within said chamber, said microphone detecting said resonating of said test disk and generating a signal upon detecting said resonations.

### Claim 2 (depends on 1)

The shot peening sensor of claim 1, wherein said microphone is held within an elastomeric isolation member within said holder.

### Claim 3 (depends on 1)

The shot peening sensor of claim 1, further comprising an accelerometer affixed to said holder, said accelerometer having an output to subtract from said signal.

### Claim 4 (depends on 1)

The shot peening sensor of claim 1, wherein said test disk is formed from a hardened resonant material.

### Claim 5 (depends on 4)

The shot peening sensor of claim 4, wherein said test disk is formed from high hardness manganese steel.

### Claim 6 (depends on 4)

The shot peening sensor of claim 4, wherein said test disk is formed from high impact resistant glass.

### Claim 7

A shot peening sensor comprising:
a holder having a bottom wall with a sidewall extending therefrom, said sidewall terminating at a top surface to form an open top, said top surface having a disk pocket surface recessed from said top surface, said sidewall having threads;
a test disk having a thickness defined by a distance between an outwardly facing surface and an inwardly facing surface, said distance being greater than a depth of said disk pocket, said test disk and said holder forming a chamber, said test disk having an unsupported area resonating in response to impacts from shot to said outwardly facing surface;
a mounting cover having complimentary threads mating with said threads on said sidewall to clamp said test disk to said holder and overlay said open top, said mounting cover having an aperture to expose a portion of said test disk; and
a Doppler vibrometer spaced from said test disk and being held within said chamber, said vibrometer detecting said resonating of said test disk and generating a signal upon detecting said resonations.

### Claim 8 (depends on 7)

The shot peening sensor of claim 7, wherein said vibrometer is held within an elastomeric isolation member within said holder.

### Claim 9 (depends on 7)

The shot peening sensor of claim 7, further comprising an accelerometer affixed to said holder, said accelerometer having an output to subtract from said signal.

### Claim 10 (depends on 7)

The shot peening sensor of claim 7, wherein said test disk is formed from a hardened resonant material.

### Claim 11 (depends on 10)

The shot peening sensor of claim 10, wherein said test disk is formed from high hardness manganese steel.

### Claim 12 (depends on 10)

The shot peening sensor of claim 10, wherein said test disk is formed from high impact resistant glass.
