Document Type and Number:
WIPO Patent Application WO/2019/054343
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide a lubricating oil sensor head which has a simple structure but can continuously measure the fluid level and fluid quality of lubricating oil. A lubricating oil sensor head (2) according to the present disclosure is provided with: a first substrate (30) which is inserted in an oil reservoir space (11) for storing lubricating oil, and has a first surface (301) and a second surface (302) on both sides thereof in the thickness direction; and a second substrate (31) disposed so as to face the first surface (301). The first substrate (30) has a first electrode (32) on the first surface (301), and a pair of second electrodes (33) for measuring an impedance, on the second surface (302). The second substrate (31) has, at a position facing the first electrode (32), a third electrode (34) for measuring the capacitance between the first electrode (32) and the third electrode (34). A gap (35) into which the lubricating oil can flow is provided between the first electrode (32) and the third electrode (34).
