A method and apparatus (100) for detecting moisture. An oscillatory electrical signal S1 generated by an oscillator (3) is propagated into a body (48) that includes an electrically insulative material (25). A signal due to S1 emerges from the body (48) as an oscillatory electrical signal S2. The signals S1 and S2 differ in phase by DeltaPhi , wherein DeltaPhi is indicative of moisture along a path traversed by S1 within the insulative material (25), and wherein the conductance sigma of the insulative material (25) is also indicative of the moisture along the path traversed by S1 within the insulative material (25). S2 is received at a sensing surface (17) of a sensing part (e.g., probe (1), sensing antenna, etc.) and then transmitted to a moisture detecting device (100). The moisture detecting device (100) determines from S 1 and S2 a measure M of the moisture as a function of DeltaPhi or as a function of sigma. |
