PC display servo steel bar tensile strength universal testing machine with ASTM
Product Description:
The testing machine is mainly designed for the tensile test, compression test and bending test of metal, also for non-metal of compression test, such as concrete and stone. If the proper
jigs are provided, it can be used for various tests in the laboratories of mills, factories, colleges and research units concerned.
It is featured with hydraulic loading, electronic force measurement, the load, the test process with curve can be displayed on the computer screen, and the data can be saved and printed out. It is overload protection. The oil cylinder is fitted on the bottom of the main frame, which is suitable for the compression test and all the annex will be provided for the technological tests of the metal.
Measuring principle:
1, tensile testing machine force value measurement is through the force sensor, amplifier and data disposal system to complete the measurement. It is known from the data mechanics that under the premise of small deformation, the strain ε at a certain point of an elastic element is proportional to the force on the elastic element, and also proportional to the elastic component. Taking the sensor of S-type testing machine as an example, when the sensor is subjected to the effect of tension P, the strain gauge is pasted on the surface of the elastic element, and since the strain of the elastic element is in direct proportion to the size of the external force P, the strain gauge is connected to the measuring circuit to measure the output voltage and then the size of the force.
2, the deformation measurement through the deformation measurement installation to measure, it is used to measure the deformation of the sample in the process of the experiment. The installation has two collets, which are connected to a photoelectric encoder mounted on the top of the measuring installation through a series of biographies. When the interval between the two collets switches, the shaft of the photoelectric encoder is driven to twist, and the photoelectric encoder will have a pulse signal output. Then the signal is processed by the processor and the deformation of the sample can be obtained.
3. The measurement of beam displacement is roughly the same as the deformation measurement, which is to obtain the displacement of the beam by measuring the output pulse number of the photoelectric encoder
