Abstract :
Structural steel changes its magnetic characteristics when pressure is applied to it. For developing a force sensor using structural steel, B-H characteristics and magnetostriction characteristics are very important factors. In this paper, an experimental force sensor was constructed. This sensor consists of sensor metal (SUS630, stainless steel, annealing), a foundation metal, and an exciting coil. The analysis of the force sensor revealed that as pressure stress increases, the coilpsilas inductance decreases. We propose in this paper that it is possible to develop a large rated load force sensor which utilizes changes in magnetic characteristics in spite of a small size.
