Abstract
A device (10) for monitoring the integrity of a wooden post (40) including an outer sleeve (11), a moveable pin (12), a spring (24) and a measuring rod (50). The outer sleeve (11) is adapted to be mounted in a pre-formed recess (41) of complementary size and shape extending from the outer surface (43) of a wooden post (40) substantially into the center (45) thereof. The moveable pin (12) is mounted within the outer sleeve (11) and has a head (18) arranged normally to bear against wood at the center (45) of the post (40). The spring (24) is arranged to urge the pin head (18) against wood at the center (45) of the post (40). The measuring rod (50) denotes any movement of the pin (12) further into the post (40).
