Sistem Pengontrolan Pressure Reducing Boiler (PRV) Berbasis Arduino Nano Pada Boiler

Today there are technological advancements in industrial process and control with the emergence of microprocessors and electronic components, Fieldbus technology, and the Internet. Because they all facilitate operation and
guarantee process optimization and operational performance and safety. However, the problem is how to design a pressure reducing boiler using a transducer and Arduino. To fix process problems and pressure control, several processes are carried out, first, the transducer will detect pressure when an object passes through the transducer and sends it to Arduino. Then Arduino will detect the signal sent by the transducer and display the readable pressure value by
displaying the numbers on the LCD. The purpose of this research is to realize a control system to control and monitor the pressure in the boiler. Based on the
results of experiments that have been carried out by entering a pressure setpoint value of 13 PSI, the servo angle is 60°, the turbine rotates 76 – 135 RPM and the
LED is active for 68 – 75 seconds with an average error of 26.66%, the pressure setpoint value is 13 PSI, the servo angle is 70° the turbine rotates 217 – 241 RPM
and the led is active for 36 – 42 seconds with an average error of 30.76%, the pressure setpoint value is 13 PSI, the servo angle is 90° the turbine rotates 241 –271 RPM and the led is active for 34 – 37 seconds with an average average error 0.26% to open the boiler. The test results show that the 60° angle is very good because it is able to rotate the turbine and activate the LED for quite a long time
compared to the 70° and 90° angles but if you want high turbine RPM you should
use a 90° angle.
