<p>Ball vibration sensor according to the invention consists of two poles (1) located on opposite sides, separated by a among pole space (3), which is formed by fastening two poles (1) in a common insulating housing (5) distance to tip or not tip distance and / or a combination both poles (1) by insulating layer / inserts (6) with a hole. Each pole (1) have poles cavity (2) open toward the centre sensor. Both poles of the cavity (2) create with the among pole space (3) enclosed hollow space inside sensor predominantly convex surface, inside which there is at least one free floating ball with an electrically conductive surface (11), in their move conduction intermittently connects two poles ( 1) through their contact surfaces (4).</p> |
