Analysis on Pressure Compensation Performance of Corrugated Diaphragm for Underwater lnstruments Pressure Compensation Element
摘要
Abstract
The compensation mechanism of the corrugated diaphragm used as the pressure compensation element in underwater pressure sensor is analyzed. Based on the compressibility of liquid,the method for analyzing the compensation performance of corrugated diaphragm is presented and the relationship among the work depth of sensor,the compensation volume of the corrugated diaphragm and the differential pressure between internal and external of pressure sensor is derived, and the process to calculate the differential pressure is also brought forward,which can be used to analyze and design the corrugated diaphragm used as pressure compensation element. The compensation performance of flat and corrugated diaphragm which have the same material and size is also analyzed. Results show that there is a depth threshold to measure the pressure compensation performance of the two kinds of diaphragm. When the water depth is greater than the threshold, the pressure compensation performance of corrugated diaphragm is better than that of flat diaphragm.关键词
