摘要： Pressure or force measurement device for static or dynamic pressure measurement, in particular for high pressures or forces, having a housing including a pressure or force measuring cell, e.g., a piezoresistive or capacitive measuring cell. In such devices, service life and chemical resistance are problematic. The pressure measurement device includes the housing, a seal between the pressure medium and an inner chamber of the housing, a pressure measuring cell having a main face exposed to the pressure medium and which pressure measuring cell having a deflection when pressure loaded, which deflection leads to a relative movement between the pressure measuring cell and the housing in a region of the seal. In a region of the seal, the housing has spring-elastic properties. The pressure measurement device further includes a flange with an elastic sealing rib forming a through opening. The housing may be rotationally symmetrical with respect to the flange.

摘要： A process for monitoring the flow of flowing media, especially for acquiring the heat transport capacity of the flowing medium, in which a measurement signal of a temperature measurement element influenced by at least one heating element and the medium flowing past it is monitored and in which an output signal is generated when the measurement signal of the temperature measurement element exceeds or falls below a switching point. A reduction of the reaction time of the process for monitoring the flow of flowing media is guaranteed by the heat output of the heating element and/or the location of the switching point changing as a function of the output signal.

摘要： The invention relates to pressure measurement apparatuses and pressure or force measurement devices for static or dynamic pressure measurement, in particular for high pressures or forces, whose housing contains among other things, a pressure or force measuring cell, e.g. a piezoresistive or capacitive measuring cell. In devices like this, service life and chemical resistance are problematic. The pressure measurement device according to the invention is essentially comprised of a housing (2), a seal (4) between the pressure medium and the inner chamber (2d) of the housing (2), a pressure measuring cell (3), whose first main face (3e) is exposed to the pressure medium and which has a deflection when pressure loaded, which deflection leads to a relative movement between pressure measuring cell (3) and housing (2) in the region of the seal (4). In the region of the seal (4), the housing (2) is embodied so that it has spring-elastic properties. The pressure measurement apparatus according to the invention is comprised of a flange (7) with a conical sealing rib (7b) in the through opening (7f) and a pressure measurement device (9) with a housing (2) that is rotationally symmetrical in the region of the flange (7). The sealing rib (7b) is embodied as an elastic sealing rib.
