膜片、膜盒等弹性敏感元件是许多仪表的重要元件。膜片膜盒的生产中常常用百分表、千分表及微动千分尺等来测量膜片型面的几何参数及元件的特性——加压或抽空时元件硬中心部分的线位移。用百分表测量刚性很小的膜片型面参数会造成不能容许的误差,用微动千分尺测量元件特性虽然测力较小,但其使用也有不便之处,特别是机械式触头中的扭丝难以制造、不易安装与调整,且极易损坏。我车间制成了电子触头代替上述机械式触头,使用效果良好。后又设计制造了简单的升 Diaphragm, diaphragm and other flexible sensor is an important component of many instruments. Diaphragm diaphragm box production often use dial indicator, micrometer and micrometer micrometer to measure the geometric parameters of the diaphragm surface and the characteristics of the components - Pressure or vacuum evacuation of the hard center part of the line displacement. Using a dial indicator to measure parameters of a very rigid diaphragm profile can cause unacceptable errors. Measuring the element characteristics with a microdispenser Although its force measurement is small, its use is inconvenient, especially in mechanical contacts Difficult to create twisted wire, not easy to install and adjust, and easily damaged. My workshop made of electronic contacts instead of the mechanical contacts, the use of good results. After the design and manufacture of a simple rise
