Gear oil tested is a polyalphaolefin (PAO) synthetic. Measurements taken successively without turning sensor off. Sensor head purged of previous test sample with dried and filtered compressed air. Figure 1 – Dialectric Sensor Output (courtesy of Kittiwake Developments, LTD) Conclusion As cost-to-manufacture decreases, sensor usage will climb, and laboratories will be increasingly nudged to alter their test selections, perhaps conducting a greater frequency of higher-end testing in order to supplement lost low-end testing to sensors, as well as to vet sensors’ findings. At this point, the die has been cast. Sensors are changing the lubricant analysis industry and will continue to do so with every technological improvement yet to come.
