A cyclone separator (60) includes a wall (92), a first passage (88), a second passage (90A), and an oil debris monitor (62). The wall defines a cyclone cavity (95). The first passage has a first passage inlet (102) positioned in the cyclone cavity and a first passage outlet (104) at an exterior of the cyclone separator. The second passage has a second passage inlet (106) positioned in the cyclone cavity and a second passage outlet (118) at the first passage. The oil debris monitor detects debris flowing through the second passage. |
