Abstract

Each radiology or X-ray device is required to perform a functional or performance test of an X-ray aircraft in accordance with the radiation safety standards of the International Nuclear Energy Agency (IAEA). The suitability test has several parameters and parts. In the X-ray Aircraft Suitability Test, there are X-ray beam collimation tests, X-ray generators and tubes, and AEC. However, the illumination and collimation test still uses the manual method. The purpose of this research is to develop the simplest method, which is to measure the illumination at four points simultaneously and store the measurement data directly. This module is designed to use the HC-SR04 sensor as a distance meter and the TSL2561 sensor as a light meter. This module is designed using the HC-SR04 sensor as a distance meter and TSL2561 sensor as a lux meter. In this research, the module has been tested and compared with the results of a comparison tool (Digital Light Meter) and got an error value of 1.55% with a module efficiency of 98.45% in the illumination test, and an error of 1.8% with a module efficiency of 98.2% in the collimator test. From this research, it can be concluded that the light sensor TSL2561 can be used to measure the illumination area of ​​the collimator lamp. The contribution of this research is expected to be more efficient tool testing, and the data will be saved until the next testing time

Abstract

Digital thermometers are measuring instruments needed to perform temperature measurement actions and must be calibrated periodically according to standard measurement methods. The purpose of developing this tool is to add PID control to the calibration media where PID control aims to regulate the stability of the temperature setting to be achieved. This is achieved by studying and evaluating the effect of temperature stability on the heater and LM35DZ temperature sensor. This research method uses the Arduino Nanosystem for data processing and PID system control. The LM35DZ temperature sensor on the heater is regulated by a 2 Channel SSR module using a PID system then the temperature generated by the heater will be read by the LM35DZ and displayed on the LCD. The results of this study, digital thermometer calibrator measurements have been successfully carried out by comparing 3 digital thermometers with different brands, namely Omron 343F, Omron 245, and ThermoOne. The difference in error values in oil media is 3-4% and in water media 2-4% with the value of time stability in water media for 3-3.3 minutes and in oil media for 1-2 hours. With this comparison of calibration media, it is hoped that it can help in measuring temperature with better and more effective results. find methods, results, conclusions.

Abstract

A surface's verticality or horizontalness can be determined as well as its flatness using a waterpass or spirit level. The alignment and flatness of the X-ray tube and bucky table, which determine the perpendicularity of the X-ray beam, is one of the factors for the Conformance Test, according to PERKA BAPETEN No. 2 of 2018. A traditional waterpass is typically used to obtain that conclusion, but the measurement outcome is still subject to human error because there is no set value. To achieve exact alignment, A digital waterpass using the MPU6050 sensor is made, which produces precise X-Ray images, reduces noise in the form of shadow magnification, and investigates the function of the waterpass in the compliance of the X-Ray unit. Arduino is used as the data processor in this investigation. The output is then shown on an LCD and transmitted over Bluetooth to a computer where it is displayed using Delphi before being saved in Excel. With the deviation standard value of 10 degrees, we have obtained an error value from this research between 2% and 3%, minimum, which is 0.04 for sensor 1 and 0.25 for sensor 2. Sensors 1 and 2 measure 14 degrees at 0.089 and 0.054, respectively. The MPU6050 sensor can be utilized in this study to determine how flat the X-Ray tube and bucky table are about one another. This study's contribution is anticipated to be more effective tool testing, and the data will be kept on file until the next testing session.
