Abstract
Areas of concentrations that can be exploited at all times, such as gas reservoirs in crude oil tanks, are called zero zones. In order to use various equipment in Zone 0, an intrinsically safe certification must be obtained that can guarantee that sparks will not occur in nature. Most devices that acquire intrinsic safety certification are mostly simple single-component devices or devices. In this study, it was a very difficult process because we intend to acquire the intrinsic safety certification of an electronic circuit including an ultrasonic generator and a microcontroller in which hundreds of components are mounted on a PCB substrate. Through this study, we have been able to understand how to design a circuit for intricate intrinsic safety certification. and Using the results of this study, it will be easier to design intrinsically safe circuits when trying to develop a circuit that can obtain intrinsic safety certification.
