Abstract:

A gauge for measuring differential pressure in an explosive blast wave, wind tunnel, or shock tube, utilizes a tubular housing having a conical axially aligned inlet port, a cylindrical cavity which is divided into fore and aft sections by a transversely disposed pressure responsive diaphragm. A plurality of symmetrically disposed off-set stagnation inlet tubes and a plurality of circumferentially positioned flow compensated side-on over-pressure input slots are used to communicate with each of the respective fore and aft sections of the cavity. Variation in stagnation and side-on overpressures cause diaphragm movement which is detected by a friction-free sensing member. Author
