摘要
To determine positive pressure, vacuum and differential pressure, a pressure-measuring device is provided which has a two-piece metal pressure housing (2), assembled to form a unit and having a mounted pointer mechanism (3), and is equipped with a measuring diaphragm (5) lying between both housing halves (2a, 2b). Via a coupling part (6), the measuring diaphragm (5) is in operative connection with a measuring-range transfer and setting mechanism (12) which is laterally arranged on the housing (2) and has a measuring shaft (13), rotatable as a function of the diaphragm lifting movement, and a link pin (14) which is kinematically connected to the measuring shaft (13), performs a pivoting movement during rotation of the measuring shaft and transmits this pivoting movement to the pointer mechanism (3). The link pin (14) is mounted on the measuring shaft (13) in such a way as to be infinitely displaceable and adjustable in the longitudinal direction of the shaft in order to set the transmission ratio.
