What machine is used to test tensile strength?

 

1. Ordinary tensile testing machine: Ordinary tensile testing machine is a general testing equipment used to test the tensile properties of materials. The equipment usually consists of a load cell and a control unit, and can measure properties such as tensile strength and elongation of materials by applying a constant tensile load on the test sample. Ordinary tensile testing machines are generally suitable for testing various materials with high precision and reliability.

 

2. Piezoelectric tensile testing machine: Piezoelectric tensile testing machine is a special testing equipment that uses the piezoelectric effect to measure the tensile strength of materials. The device uses a piezoelectric sensor to convert the tensile load applied to the specimen into an electrical signal to measure properties such as tensile strength and elongation of the material. Piezoelectric tensile testing machines are generally suitable for measuring the tensile properties of high strength materials.

 

3. Profile projector: A profile projector is a non-contact testing device for measuring the tensile strength of materials. The device uses cameras and optical sensors to record the profile changes of the test sample during stretching, thereby measuring properties such as tensile strength and elongation of the material. Profile projectors are usually suitable for measuring thin metal materials, etc.

 

4. Laser scanner: A laser scanner is a high-precision testing device for measuring the tensile strength of materials. The device uses a laser scanner to record the deformation and deformation of the test sample during stretching, thereby measuring properties such as tensile strength and elongation of the material. Laser scanners are generally suitable for measuring high-precision metal materials, etc.

 

In a word, the above equipments are commonly used equipments for testing the tensile strength of materials, and are suitable for testing the mechanical properties of various materials. When performing a tensile strength test, it is necessary to select appropriate test methods and equipment according to the characteristics of the test material and application scenarios to ensure the accuracy and reliability of the test results.
