摘要 |
FIELD: instrument making.SUBSTANCE: proposed transducer comprises cup with cylindrical cavity filled with compensating fluid. Said cavity is isolated from outer medium by seal ring with rigid sensitive cylinder-shape element fitted there through and having smooth surface in contact with outer medium. Sensitive element is arranged to displace in lengthwise direction and provided with resilient lead-out extending as-sealed from the case. Seal ring is fitted in crosswise groove with cross-section shaped to truncated cone diverging from the cup bottom. Seal ring via washer towards cup bottom by sleeve fitted in said case to displace therein.EFFECT: higher reliability of sealing of sensitive elements.1 cl, 2 dwg |
