The inductance gauge converter has a complex structure, can be fabricated, offers high sensitivity, whilst keeping its general simplicity signal processing circuits. It is also easy to be paired with others measuring devices. Hence, the knowledge about them is very limited, and the entire converter cluster often comes with a non-commercially available module, making maintenance challenging and expensive. At present, the formula documents related to inductance measurement conversion are limited and very few, so it is difficult to calculate the design. And there has not been a single study of this type of conversion applied to displacement measurement systems. In this topic, an experimental design and a construction of experimental linear lines of inductive conversion for integration with suitable gauge mechanisms are presented. Facilitating the use, exploitation and manufacture of equipment with high sensitivity and accuracy. Master the technology of making expensive gauges. In order to manufacture and test the inductance measurement conversion on roughness measuring equipment, pressure measuring equipment, force measuring equipment ….
