Product Description

Scope of application
Computer type automatic spring testing machine, according to the national standard JB/T7796-2005 "spring tension testing machine technical requirements of the technical requirements. This machine is suitable for a variety of coil spring slightly tension and pressure test. The machine can automatically test the free length of the spring, while out of the four points of the force and spring coefficient. The machine has good precision and repeatability and is widely used in spring factories and scientific research institutions.

Product features
1, can automatically determine the spring tension, pressure and elastic coefficient, can be measured at the same time four points;
2, touch screen operating system, easy to operate;
3, the force index value can be freely set up to three decimal places 0.001N. Displacement up to 0.01MM;
4, with automatic and manual zero capture function. Can achieve efficient zero capture, power automatically remember the height;
5, the pressure test can achieve the height method and deformation method double test (pressure method: can achieve the test of the corresponding force when the spring compression is left long. Deformation method: How much downward compression can be achieved after touching the spring. Both functions can measure 4 points simultaneously).
6, through the preload and rigidity compensation correction to ensure the accuracy of the measured value;
7, load sensor overload protection and emergency stop function;
8, with a micro printer.
