| 摘要 |
The present invention relates to the field of means for measuring physical magnitudes and more precisely to a cell for measuring pressures. According to the invention, a cell (1) for measuring the pressure, implementing a pick-off (2) comprising a deformable membrane (3), said pick-off being housed into a correspondingly shaped recess of a cell body (5) wherein the pick-off is held by a cover (4), is essentially and generally characterized in that the pick-off being in place in the recess, the cover (4) is peripherally sealed (6) to the body (5) of the cell; a preferred mode of sealing is welding. Applications to the measurement of pressures or differential pressures in chemical or petrochemical plants. |
