An Experimental Study of Measuring Oscillatory and Transient Pressures in Hydraulic Systems.

Abstract

This study is concerned with two basic techniques for measuring oscillatory and transient hydraulic pressures: use of a standard fluid line transducer (in-line) and a transducer clamped to the outside of the line (clamp-on). Both transducers were installed in a laboratory hydraulic system side by side. Several sets of runs were made under various conditions. Measurements taken indicated deviations between the two transducers as high as + or - 20%. The clamp-on transducer was affected by the line vibrations and should be used in a hydraulic system with some limitations. The experimental measurements were compared with the theoretical results from a frequency response computer program. The measured oscillatory pressures were up to 30% greater than those predicted by the computer. (Author)
