Abstract: In the rapidly development of automatic control systems over all the kind of industrial societies, electro-magnetic proximity sensors have been provided for the very important roles. It will be reported in this article that we want to propose the damping oscillation type, using a ringing circuit, has more merits and better features compared with than the well known high frequency oscillated types. In the system, the damping coefficient varys with according to moving the distance, which will be detected the difference of the positions of two ones, i.e., the detected target and the sensor coil used in it. Just for the above mentioned reasons, that system is quite suitable for a digital signal processing, because the slop coefficient of the envelope of the damping form in the damping oscillation, may be easily converted into the pulse numbers. Furthermore, using the system, we have made them practice those, which are 1) to expand the range of operations, 2) to have the expandable sensitivity and 3) to make the posibility of construction of simplified circuits using a PUT device. After all, we will report the experiments and the consideration of the above described materials in this paper, below.
