Abstract

The invention discloses an external dynamic test cylinder of a sensor, comprising a speed sensor (3), a piston (8) and a displacement sensor, the external dynamic test cylinder is characterized in that an integral structure is mainly composed of three parts: a dynamic cylinder, the speed sensor (3) and the displacement sensor (11). The external dynamic test cylinder of the sensor, provided by the invention, is easily manufactured, convenient for installing, debugging and maintaining, medium in test precision, and good in practicality, meets the frequency characteristic test requirement of an electro-hydraulic servo valve commonly used in the industry, and is particularly suitable for a test device and an experimental table for training and teaching.

Description

technical field [0001] The invention relates to the field of sensor experimental devices, in particular to an external sensor-mounted dynamic test cylinder. Background technique [0002] The frequency characteristic test is an important part of the dynamic performance test of the electro-hydraulic servo valve, and the dynamic test cylinder is a necessary device for the frequency characteristic test of the electro-hydraulic servo valve. The traditional dynamic test cylinder is built with specially designed and manufactured speed sensor and displacement sensor to obtain the flow signal of the tested valve and the position signal of the hydraulic piston, as shown in the attached image 3 shown. Due to the difficulty of manufacturing, strong professionalism, difficult maintenance and high price, it has always been unique to professional production enterprises. With the increasingly wide application of hydraulic servo technology, the demand for frequency characteristic testin...
