Proximity probe sensor is vital for monitoring the condition of the rotor within journal bearings. One of the requirements for ensuring the measurement results are reliable is an ERO (Electrical Run Out) value below standard. At the moment, there are two commercially available portable ERO measuring instruments, AccuScan XE200i and CMCP810. However, both instruments are made to order and expensive. Therefore, the software of portable ERO measuring instrument is designed and made using the available hardware at PT. Sulzer Indonesia. This final project begins with a survey of similar products. The survey results are used as a basic idea in designing software of portable ERO measuring instrument. The idea was then developed in accordance with the availability of hardware, namely Raspberry Pi 3B+ and Picoscope 4824. After that, the software was created and tested. Testing aims to determine the precision of measuring instruments. The portable ERO instrument that has been made will measure the ERO value of a particular rotor. The measurement result is then compared with the measurement results using Labview and multimeter. In this final project, the software of portable ERO measuring instrument has been successfully made in accordance with the available hardware at PT. Sulzer Indonesia and with affordable price. Based on the tests that have been done, the software can function properly. The relative error of the measurement result is below 3% so the measuring instrument is precise.
