Is the non-contact full-field strain measurement system expensive?

At present, there are many kinds of non-contact full-field strain measurement systems at home and abroad, and the prices are different. If we analyze them in detail, it is impossible to say a completely certain price.

In China, from the brand point of view, there are three companies with relatively perfect equipment services: GOM, CSI and Xibo Sanwei. At present, there is not much difference between the three companies in technology. The products are basically used in relatively high-end research institutes or some key universities, such as Tsinghua, Zhejiang University and Tongji in China, and ABB and Audi abroad. Tongji has invited these three companies to conduct a tender before, which is also the recognition of their products. Among the three brands, the first two are foreign brands, and they are sales agents in China, while the latter is a domestic brand with technology from Xi Jiaotong University. From the brand point of view, the general foreign conventional equipment should be around 600,000, and the basic advanced functions are around one million. Domestic brands are relatively affordable, and the conventional equipment should be around 400,000, but the high-end products are also over one million.

From the application point of view, there are high-temperature strain measurement, failure experiment measurement, large-scale tensile measurement and so on. Different applications need different configuration schemes. This can only be analyzed by specific experiments, and the difference is too great. It is best to ask the manufacturer according to the specific situation.
