MECHANOELECTRICAL TRANSDUCER Russian patent published in 1998 - IPC

FIELD: production process automation. SUBSTANCE: transducer has electrically insulated body, current-conducting base and plunger provided with force receiving and force transmitting areas, respectively. Space between force transmitting areas of base and plunger is filled with electric conducting liquid, and surfaces of force transmitting areas are made equidistant and have coating nonwettable with liquid. Coatings of force transmitting areas nonwettable with liquid may be made of dielectric. Dielectric coating of base may be of high resistance. It can be manufactured for example in the form of Archimedean spiral. Electric conducting liquid may be represented by mercury. Surfaces of force transmitting areas of base and plunger are made spherical. EFFECT: improved control and measurement processes. 6 cl, 2 dwg
