PROBE ASSEMBLY FOR A FLUID CONDITION MONITOR AND METHOD OF MAKING |
摘要 |
A probe assembly for use in monitoring fluid conditions in real time in a transducer utilizing impedance spectroscopy and having two closely spaced tubular concentric electrodes. The electrodes have a surface area of about 8.1 to 10.8 cm<2 >spaced in the range of about 0.1 to 0.55 mm. In one embodiment a concentric outer tubular Faraday shield is employed for monitoring fluid in a non-metallic vessel. The probe assembly is particularly suitable for monitoring hydraulic fluid including automatic transmission fluid and mineral based engine oil for diesel and gasoline engines. |
