PENDULUM Models DIRECT and INVERTED

The direct pendulum consists of a wire suspended from the upper point and a reading station fi xed to the structure at the lower point. The wire is tensioned by a suspended weight submerged in a damper tank. Inverted pendulum The fi xed end of the inverted pen dulum is grouted at the lower point of the system. A fl oat tensions the wire vertically. When anchored to a fi xed point in the foundation, it measures absolute displacement of points along the wire. The monitoring of the wire position for both direct and inverted pendulums can be done manually and/or electrically with a remote readout unit (ref: Model RxTx Telependulum – see separate brochure). The method of reading depends upon the concept of monitoring, the ex pected values of movements, and the accuracy required. The pendulum may be equipped with a Z axis reading table, for vertical deformation
