How to choose a tensile testing machine

 At present, there are many manufacturers of electronic tensile testing machines in the domestic market ; coupled with the presence of foreign brands and various types of dealers and offices, this market is very messy; because each manufacturer has uneven levels in terms of quality and manufacturing processes. , resulting in price deviations, and even a big difference , then how do we choose the electronic tensile testing machine that suits us? Let's take a brief look at the purchase method :
 
First, we must understand the difference between the electronic tensile testing machine and the hydraulic tensile testing machine.
  1. The working principle of the electronic tensile testing machine: the motor drives the screw to rotate through the reducer, the screw drives the beam to move up and down; the force sensor is mounted on the moving beam , and the sensor outputs the data through the data line and the control software.
  2. The scope and characteristics of the electronic tensile testing machine: The electronic tensile testing machine is suitable for the tensile and bending test of small force samples (usually less than 300KN) for metal and non-metallic materials such as rubber, plastic, packaging materials, steel wire and copper wire. The electronic tensile testing machine has the advantages of high measuring precision and low working noise; the national standard is required for the accuracy of the electronic tensile testing machine: better than the first level.
  3. The hydraulic tensile testing machine is divided into two parts: the loading system and the measuring system; the loading system transmits the force to the force sensor through the cylinder piston, and the force sensor converts the force signal into an electrical signal and transmits it to the measuring system. The hydraulic tensile testing machine is suitable for the tensile and bending tests of large-value samples (generally larger than 300KN) such as steel, profiles, steel wire ropes and reinforced concrete.
