Abstract
A Study on the Development of Exclusive Sensor for Detecting the Hydraulic Cylinder Stroke





In order to comprise a basic closed-loop control system for hydraulic systems it is necessary to detect the piston rod stroke of hydraulic cylinder. There are many conventional type sensors which have been applied to detect the displacement of cylinders. Several types of LVDTs and magnetic sensors are representative illustrations of them. However, they cannot reveal the original performance normally or they cannot be applied at all where the operating circumstance of cylinders is beyond specifications of sensors. Especially, for the purpose of detecting the strokes of cylinders mounted on heavy equipments, a special exclusive sensor must be used. Because the operating circumstances of heavy equipments are so severe that general purpose sensors cannot endure such circumstance as a shock and a residual vibration induced by rough works. In the conclusion, an exclusive sensor must be developed to detect the strokes of hydraulic cylinders of heavy equipments.


In this thesis, an exclusive method for detecting the piston rod stroke for heavy equipments is suggested, which adopts a remote detecting technique using optical sensors and optical fibers. To do this, first of all, a kind of scale treatment of piston rod is required and it is also proposed here. An entire implementation procedure of the proposed exclusive sensor is explained concretely. A prototype of the sensor is resulted from the procedure. And then, several experiments using the prototype are executed for verifying the effectiveness of the suggested method and the possibility of the remote detection. Finally, the conclusion is demonstrated based on the experimental results.
