Non-Invasive, On-line Oil Condition Sensor (317)
Problem: Need rapid, non-destructive, on-line detection of a number of chemical indicators of motor oil degradation
Project Activity Scope (from Technical Overview Chart): Mechanisms through Sensors and Devices
PNNL Solution:
- Analyze new and used oil samples to identify optical signatures for key indicators of oil degradation (e.g., oxidation, nitration, sulfation, and water contamination)
- Lab test system reliably detected specific oil degradation conditions using in-line flow cell
- Established design for practical sensor using measurements at discrete wavelengths
Capabilities Employed to Meet Client Needs: Spectral transmittance (visible-infrared spectral regions) measurements on variety of oil samples to determine key spectral features for detecting target parameters; designed practical in-line optical cell to support on-line application requirement; bench level optical system design and assembly; proof of concept testing; data analysis; reporting.
