FIELD: measuring equipment. ^ SUBSTANCE: manometer includes case, sensitive element, gauge face, gauge hand and glass. Manometer case is made in the form of blunted cone with flange transiting into cylinder. In central part a gauge face in the form of tube surrounding working part of sensitive element is pressed inside the cylindrical case part up to the stop at flange. Working part of the sensitive element blends into feeding part connected tightly by one end to socket hole in the case, contacting measured medium. A space is formed between gauge face walls and glass, where a gauge hand is mounted. Under shock and vibration affecting manometer the gauge face and glass limit hand end movement. Internal cavity of sensitive element contacts measured medium, free end of sensitive element with gauge hand mounted on it turns under effect of medium pressure at a definite angle, and measured pressure value is read on the gauge face scale against the long end of gauge hand. ^ EFFECT: enhanced accuracy and reliability of pressure measurement and control, simplified construction, and reduced manometer cost. ^ 5 cl, 4 dwg |
