微小流量的测试应用范围极为广泛,测试方法也较多。我们所研制的这种测试仪,实际是一种闭环测试系统。它采用体积法测量原理并应用当今的光电、单片机等各种先进技术构成。由于大量工作靠计算机软件完成的,因而整机硬件结构简单。本测试仪具有测试精度高、工作可靠、操作简便、自动化程度高等优点。此测试仪具有齐全的通讯接口,尤其适合于对液压元件泄漏量进行测试的场合。 The application of a small flow of test is extremely wide range of test methods are more. We developed this tester, is actually a closed-loop test system. It uses volumetric measurement principle and the application of today’s optoelectronics, microcontrollers and other advanced technology. As a large number of work done by the computer software, so the whole hardware structure is simple. The tester has the test of high precision, reliable, easy to operate, high degree of automation advantages. This tester has a complete communication interface, especially suitable for the hydraulic components leak test.
