Sensing device for measuring volume, position, or mass of matter

摘要

A novel sensing device having a unique structure, for measuring volume, position or mass of matter ( 11 ) comprising of a housing ( 12 ) having a removable top ( 13 ), a permanent bottom ( 14 ), an electronic oscillator board ( 15 ) having plurality of electronic components for measuring volume, position, or mass of matter. A coax type wire ( 16 ) having a first end ( 17 ) connected to said electronic oscillator board ( 15 ) and a second end ( 18 ) terminating at the bottom of receiver hole ( 20 ). A retainer ( 19 ) used to form said receiver hole ( 20 ) having a top end ( 21 ) open to said permanent bottom ( 14 ) on said housing ( 12 ) to accommodate said coax type wire ( 16 ). Said receiver hole 20 having a bottom end ( 22 ) and lower end ( 25 ) being isolated by said non-conductive material ( 23 ). Said non-conductive material ( 23 ) having an upper end ( 24 ) being attached by mounting means ( 26 ) to said permanent bottom ( 14 ) of housing ( 12 ).
