Abstract
The front edge (2) of a manometer casing (1) is curved inwardly and secures the window shield (3), located in a sealing ring (5), against being pushed out upon superatmospheric pressure in the housing. A partition (17), in which slotted holes (18, 20, 21) are provided for the indicator shaft (19) and for the bolts (16), is arranged between the support (8) for the indicator mechanism (13) and for the bourdon tube (14) and the dial (15), which is held by bolts (16) at a spacing from said support. The slotted holes extend in a direction running from one casing hole (7) to the axis (29) of the housing and are measured to be sufficiently long, so that the support (8) with the dial (15) and the longitudinally displaceable partition (17) located between them is insertable through the rear opening (24) of the casing (1), wherein an extension (10) on the support (8) is to be outwardly displaced through the casing hole (7). The manometer casing (1) can be manufactured by deep-drawing a sheet metal part, and the measuring unit (27) can be solidly assembled and calibrated with the dial (15) and the pointer (28) before this measuring unit is mounted into the housing (1).
