Types of sensors configured on electronic tensile testing machines

Types of sensors configured on electronic tensile testing machines7tiTextile Testing Instruments, Testing Equipment Manufacturer

Electronic tensile testing machines generally come with two types of sensors equipped sensors, one is a load cell, used to test the tensile, compressive, bending, shearing and other stress forces of the sample; the other is a displacement sensor used to test the displacement distance of the movable beam. 7tiTextile Testing Instruments, Testing Equipment Manufacturer

1. Load cells7tiTextile Testing Instruments, Testing Equipment Manufacturer

Commonly used load cells on electronic tensile testing machines are divided into miniature sensors, S-sensors and spoke sensors with different measuring ranges. 7tiTextile Testing Instruments, Testing Equipment Manufacturer

1. Miniature Sensors: The measurement range is mostly 0-50N, mainly for testing the tensile strength of single fibers and single yarns, and the maximum measurement range can reach 20kN. Small, generally used for testing machines such as single fiber strengtheit tester and single yarn strength tester, and select the appropriate range according to the maximum tensile strength of the sample. 7tiTextile Testing Instruments, Testing Equipment Manufacturer

2. S-Type Sensor: The most widely used force sensor in electronic tensile testing machines with a range of 0-100N/500N/1000N/2000N/5000N/10kN/20kN and other specifications, which can test samples For tension, compression, bending, shear, peel and other loading forces, brand manufacturers of electronic tensile testing machines mainly use S-type sensors imported from abroad and sensors from the United States, Germany and Japan are common. 7tiTextile Testing Instruments, Testing Equipment Manufacturer

3. Wheel spoke sensor: The force sensor is widely used in electronic tensile testing machines. Extension, compression, bending and other loading forces are generally suitable for metals, composites, nanomaterials, etc. with relatively large loads, and many testing machine manufacturers imported brands are used. 7tiTextile Testing Instruments, Testing Equipment Manufacturer

Second displacement sensor7tiTextile Testing Instruments, Testing Equipment Manufacturer

Equipped with a displacement sensor on the electronic train testing machine, it can be used to test the displacement and the displacement speed of the movable beam can be used. Since there is no need to prepare dumbbell-shaped specimens when stretching materials such as fabrics and leather, it can be assumed that the displacement distance of the movable beam is equal to its elongation at break.7tiTextile Testing Instruments, Testing Equipment Manufacturer

If it is rubber, It is only a rough understanding of the elongation of the sample, and it is not necessary to measure the elongation that accurately. In terms of elongation, it can be assumed that the displacement distance of the movable beam is equal to its elongation at break, however, when rubber is used to accurately test the elongation at break of specimens such as rubber, plastic and metal rods, kann cannot simply be assumed that the displacement of the moving beam is equal to its elongation at break. Because the dumbbell-shaped sample is thin in the middle and thick at both ends, the whole sample does not stretch at exactly the same rate when stretched, and particularly large Auxiliary Displacement Tester, Electronic Extensometer, and Large Deformation Extensometer. 7tiTextile Testing Instruments, Testing Equipment Manufacturer

Electronic Extensometer: Mainly used to test low deformation materials such as metal Clamp the sample clamp in the center of the dumbbell-shaped sample to test the elongation of the central part of the sample B. A displacement reference, is the measured strain relatively accurate7tiTextile Testing Instruments, Testing Equipment Manufacturer

Large Deformation Extensometer: Mainly used for materials with large deformation such as rubber, plastic, film, etc. The elongation of these materials varies from 100% to 1000%, the large deformation extensometer that must be used, i.eTest the elongation of the middle part of the sample by clamping the sample clamp to the middle of the dumbbell-shaped sample and using this as a displacement reference to calculate the elongation rate relatively accurately. 7tiTextile Testing Instruments, Testing Equipment Manufacturer
