Abstract

Proyek akhir ini bertujuan untuk merancang sistem pengujian sensor tekanan otomotif menggunakan test bench yang terintegrasi dengan antarmuka LabVIEW. Sistem ini berhasil dikembangkan menggunakan kontroler Arduino Atmega 2560 pro mini untuk mengatur aktuator masukan dan keluaran udara. Input solenoid valve dikendalikan secara manual melalui LabVIEW, sementara output solenoid valve beroperasi otomatis jika tekanan melebihi setpoint. Hasil pengujian menunjukkan bahwa test bench mampu bekerja pada rentang tekanan 96 Psi, dengan resolusi filter regulator sebesar 2,9 psi dan tingkat kebocoran 0,24941 bar pada tekanan 4 bar selama 5 menit. Sensor pressure transducer yang diuji menunjukkan performa tinggi, dengan akurasi rata-rata >99%, error ≤0,39%, sensitivitas stabil sebesar 0,10339 mA/Psi, serta histeresis dan tekanan langsung yang kecil (<0,1 mA dan <1 Psi). Sensor ini juga memiliki rentang kerja 4–20 mA dan span 16 mA, serta menunjukkan linieritas yang konsisten berdasarkan persamaan Oideal=0,10339x+3,97496O. Pressure switch yang diuji menunjukkan respons digital andal dengan tekanan close pada 50,33 Psi, tekanan open di bawah 25 Psi, dan deadband sebesar 30,11 Psi. Karakteristik dinamik menunjukkan bahwa pressure transmitter memiliki performa unggul pada setpoint lebih tinggi (3 bar) dengan error steady state yang kecil, osilasi rendah, dan waktu stabil lebih cepat. Sebaliknya, pressure transducer menunjukkan keunggulan pada setpoint lebih rendah (2 bar) dengan error steady state lebih kecil dan osilasi yang stabil. Secara keseluruhan, sistem ini telah menunjukkan stabilitas, responsivitas, dan keandalan yang baik untuk pengujian sensor tekanan otomotif.

This final project aims to design an automotive pressure sensor testing system using a test bench integrated with a LabVIEW interface. The system was successfully developed using an Arduino Atmega 2560 controller to manage the input and output air actuators. The input solenoid valve is manually controlled via LabVIEW, while the output solenoid valve operates automatically when the pressure exceeds the setpoint. Test results show that the test bench can operate within a pressure range of 0–6.5 bar, with a filter regulator resolution of 2.9 psi and a leakage rate of 0.24941 bar at 4 bar pressure over 5 minutes. The tested pressure transducer sensor demonstrated high performance, with an average accuracy of >99%, an error of ≤0.39%, stable sensitivity of 0.10339 mA/psi, and minimal hysteresis and direct pressure effects (<0.1 mA and <1 psi). This sensor also has a working range of 4–20 mA and a span of 16 mA, showing consistent linearity based on the equation Oideal=0.10339x+3.97496. The tested pressure switch exhibited reliable digital responses, with a close pressure of 50.33 psi, an open pressure below 25 psi, and a deadband of 30.11 psi. The analysis of how the pressure transmitter reacts showed it worked better at higher settings (3 bar), with fewer errors that stayed the same, less bouncing around, and quicker times to settle down. In contrast, the pressure transducer excelled at lower setpoints (2 bar) with smaller steady-state errors and more stable oscillations. Overall, the system demonstrated good stability, responsiveness, and reliability for the automotive pressure sensor test bench.
