Device for measuring absolute pressures, of the pliable diaphragm type which cooperates with a capsule having rigid walls and containing the diaphragm. In the initial assembly stage, the diaphragm completely mates with the surface of either rigid wall of the capsule, so that virtually no air is sealed therebetween. On completion of the assembly, a preload is imparted to the diaphragm by means of an externally mounted spring, so that a vacuum is created between the diaphragm and the rigid wall confronting the diaphragm with the device being adapted not only to measure absolute pressures, but also to control servo devices in response thereto. |
