Test Principle
Shaft switch load displacement curve tester Through a set of precision structure of automated assembly line, realize automatic loading, automatic testing, automatic material separation and other products to achieve grade separation. The software and microcontroller are self-developed and have intellectual property rights certificates.
Applicable to all kinds of shaft key switch (load - travel) and (resistance - travel) curve test, the use of WINDOWS Chinese window screen settings, simple and convenient operation, and all information can be stored (test conditions, load curve graph, test results, check reports ... etc.).
This machine adopts servo motor drive, which can provide high precision (load-stroke) measurement, and can get completely accurate key and switch curve test. Through the computer analysis system, it can accurately measure the relative change curves of the load and stroke of the object to be tested, and accurately control the load and stroke, test speed, setting times and pause times, etc., and it can be set up in groups based on the same test object for easy comparison. During the test, all curves are generated automatically, eliminating the tedious operation of moving paper and pencil for the old-style load curves. This machine uses servo motor and Windows control system, easy to operate, and all the data can be stored, is definitely a reliable high-performance measuring instrument.
