High-Pressure Vibrating Pressure Transducer
Abstract:
The report describes the modifications and testing done to develop a high-pressure version of the vibrating cylinder pressure transducer previously developed at Hamilton Standard Division. The previous designs of this device were rated at 20 and 50 psia maximum pressure and -65F to 250F operating temperature. The modification is rated at 250 psia and -65F to 200F. In addition, the results of a company project to develop a modification for higher temperatures up to 400F are reported. The vibrating cylinder pressure is an extremely accurate device which is currently being used in the air inlet control of the F-15 aircraft. It is small and light and has no moving parts aside from the vibrating member, so its life is indefinitely long.
