In order to accurately test the force of the pressure spring, a fully automatic insertion and extraction force testing machine with a computer model is used for testingLW-1220S。It can accurately test the elastic stroke curve of the compression spring. Recommendation for testing the elastic stroke of compression springsLW-1220S equipment.The insertion and extraction force testing machine adoptsDSP digital acquisition technology control, industrial Ethernet data transmission, effectively solves the instability problem of analog data transmission, and ensures stable connection between machines and computer systems. Sampling rate up to10KHZ， The sensor protection is fast and can overload up to 500% without damage; Suitable for various mechanical analysis tests and projectile load height tests; And testing the insertion and extraction forces of various connectors,collocationThe automatic heart seeking device will enable accurate insertion and extraction force testing. This machine is also suitable for testing the travel load of small shrapnel, utilizingPC machineThe Chinese screen setting of the window is simple and convenient to operate, and all data can be stored.
