O₂ Testing Optimization

Project 1 — Wireless Data Transmission

The Problem

The existing testing pipeline required manual data collection, limiting throughput and introducing latency in performance analysis. I was tasked with automating data transmission and enabling remote access to test results.

The Solution

I implemented a system using a Remote Terminal Unit (RTU) — specifically the RT600 by WLINK — to wirelessly connect the dissolved oxygen sensor to a server. I coordinated directly with both WLINK and the DO sensor manufacturer to correctly pair the two devices and configure the data pipeline.

Project 2 — Custom O₂ Measurement Instrument

Sensor Selection

I began with extensive research to identify sensor types that could meet the project requirements. After communicating with organizations across multiple countries, I selected the TO2-19 Hybrid Sensor Cell by Southland Sensing Ltd. as the optimal solution for measuring oxygen in a gaseous state.

Instrument Design

Since the sensor requires the water sample to be fully vaporized, the instrument needed an internal chamber capable of heating water to 100°C. After evaluating several heating methods, I settled on induction heating for its precision and compactness. I also learned and applied KF-40 vacuum fittings and piping standards to design the instrument's structural assembly.

Outcome

Due to part lead times, I was unable to complete assembly and testing before my internship ended. However, I maintained thorough documentation throughout — including sensor specs, design rationale, supplier contacts, and assembly drawings — enabling the nanobOx team to continue the project seamlessly after my departure.
