| titleOfInvention | Multi-level machine vibration tester marker pen |
| abstract | The small tester is hand held by the writing pen body ( 21 ) when testing vibration with a housing mounted vibration probe ( 15 ) mechanically driving a piezo element ( 12 ), acted on by weight ( 11 ). The piezo element ( 12 ) has electrical connection ( 13 ) through an electronic circuit to an electronic display ( 22 ) indicating predetermined levels of vibration amplitude. The multi-level LED display ( 22 ) consists of four different coloured LED's where illumination of a specific coloured LED indicates a specific predetermined level of vibration amplitude. The electronic display ( 22 ) changing illumination of specific LED's from the lowest indicated level of vibration to just reach the highest indicated level of vibration is a nominal 6 dB increase in vibration amplitude at predetermined frequencies. The electronic display ( 22 ) though not necessarily in engineering vibration units can be digitally corrected to engineering vibration units on a computer display using an electrical connection ( 26,27 ) and suitable software and interfacing device. Simple frequency analysis for determination of a possible dominant frequency can also be performed using an electrical connection ( 26,27 ) to a frequency reading digital multimeter ( 30 ). Permanent data can be written on the machine surface at the test location using the marker pen writing nib ( 25 ). A very low cost tester for day to day use by maintenance workers in a typical factory. |
