VIBRATIONAL DETECTOR Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: device has vibrational overload transducer, which has non-ferrous case provided with a cap. Inertial element is disposed inside the case; the element is made in form of electro-conducting ball. Top electric contact is made in form of hollow truncated cone and fixed to the cap. Lower electric contact is insulated from top one and made in form of hollow cone. The lower contact is attached to the case and turned with its base to the base of truncated cone. Calculator 7 has the first group of inputs and the second input connected with the first group of outputs and the second output of vibrational overload transducer. The first group of outputs is connected with group of inputs of overload direction indicator 8. The second output is connected with input of overload indicator 9. Overload transducer has central and annular electric contacts 10 and 11, which are insulated one form the other, contacts io and ii are located at top part of electric contact 6 and insulated from it either. Moreover, at initial position, central and annular electric contacts 10 and 11 are circuited together through electro-conducting ball 4. Top electric contact is made in form of sectors being insulated one from others. The sector have individual electric outputs, which have to be the first group of outputs of overload vibrational transducer. The second output of the detector is connected with annular electrode 11. Central and lower electric contacts 10 and 6 correspondingly are connected with positive bus of power supply 12. EFFECT: widened operational capabilities. 2 cl, 3 dwg
