Abstract
Salah satu sensor yang digunakan dalam teknologi fuel
injection adalah sensor oksigen. Seperti alat ukur lainnya, sensor
oksigen bisa mengalami penurunan kemampuan pembacaan. Jika
hal ini terjadi maka tegangan yang dikirim sensor oksigen ke
ECU tidak sesuai dengan kondisi sebenarnya. Hal ini dapat
menyebabkan performa mesin menurun. Untuk mengetahui
kemampuan pembacaan sensor oksigen maka suatu alat
diperlukan untuk mengkalibrasi sensor oksigen.
Perancangan dan pembuatan alat kalibrasi sensor oksigen
didasarkan pada kadar oksigen dari perhitungan gas ideal
dengan prinsip volume tetap. Dengan mengukur nilai tekanan
dan temperatur gas campuran nitrogen dan oksigen dalam
tabung kalibrasi, maka kadar oksigen dapat diperoleh dengan
menggunakan persamaan gas ideal.
Pada penelitian ini telah berhasil dibuat alat kalibrasi
sensor oksigen yang memiliki kapasitas pengukuran 0-22 %
oksigen. Alat kalibrasi sensor oksigen memiliki tekanan operasi
1,5 bar dan temperatur operasi 27-29o
C. Dari validasi yang
dilakukan pada alat kalibrasi, diperoleh penyimpangan
pembacaan 0,438 dengan kecermatan 6,34 %.

One of the sensors used in fuel injection technology is
oxygen sensor. Similiar with other measuring devices, reading
ability of the oxygen sensor declined. It gives different voltageto
the ECU. This difference make the engine performance
decreased. To determine the reading ability of the oxygen sensor,
special tool is required to calibrate the oxygen sensor.
Designing of the oxygen sensor calibration tool based on
the precentage of oxygen in fixed volume with the ideal gas
formulation. The precentage of oxygen can be determined by
measuring presssure and temperature of the gas mixture of
nitrogen and oxygen in the calibration can.
This study has been successfully designed the oxygen sensor
calibration tool which have measuring capacity 0-22% oxygen.
This oxygen sensor calibration tool have operation pressure 1,5
bar and operation temperature 27-29o
C. Based on the results of
validation found the deviation value is 0,438 and the precision
value is 6,34%.
