Abstract

In previous research of non-destructive testing, SFD settings and shifts were carried out with a specimen table connected by ball screw transmission and controlled by a stepper motor. In addition, the input value in the form of SFD is less effective because the operator needs to calculate the minimum SFD value before using the specimen table. The system can only use the calculation of SFD parameter. This study aims to simulate the development of a control system that can adjust the height of the control table to regulate the SFD / SOD using an ultrasonic sensor and compare it to the minimum SFD needed for irradiation. The results of the control system simulation test have featured an ultrasonic sensor that can be used to determine the distance of the test object to the focal spot, thickness/diameter of the test object, and regulate the vertical and horizontal movements of the regulating table. In addition, the control system can determine the suitability of the SFD entered using a matrix keypad with the minimum SFD applicable to a radiography test irradiation. In this research, a simulation has been made to develop a control system using an ultrasonic sensor that can regulate the movement of SFD and ultrasonic sensors so as to determine the minimum SFD of SOD irradiation. The control system can measure plate thickness or pipe diameter with a minimum thickness of 31 mm and a maximum of 140 mm in the SFD method and the SOD method.
