1. The protective performance of instruments and equipment should be targeted. If in contact with corrosive media; There is no mechanical wear phenomenon; What load to bear; What environment to install in; What are the requirements for the appearance of the instrument, etc.
2. Materials and protective layers that are absolutely impermeable do not exist. So, you have to think about the materials and protective layers that are used on the instruments, and how much they are allowed to erode when they are eroded. For the detection instrument, such as cylinder compression method, the steel beam on the plasticizer after corrosion will affect the elastic limit, thus affecting the accuracy of the plasticity index measurement.
3. To solve the protection problem of the instrument, we can start from the following three aspects: selecting protective materials, adopting protective layer technology measures and improving the instrument structure.
4. The instrument installation position should be improved as much as possible. If it can be installed indoors, it should not be installed outdoors; Can be installed in a cool and dry place, do not install in the sun exposure, wet shade, etc.
5. in order to protect the accuracy of the instrument, should not use isolators or other isolators to protect the instrument.
Economy is one of the basic principles of socialist economy. To solve the problem of instrument protection, it is also required to achieve good protection performance, and to achieve economic and rational, local materials, simple economy principle.
