CGEO-APR Automatic Pendulum Readout

Description

CGEO-APR Automatic Pendulum Readout can be used with both hanging and inverted system to precisely monitor horizontal displacement changes at different elevations in structures such as dams, ship locks, and high-rise buildings. The instrument's LED display can directly show displacement data.

Applications

Dams and dam foundations

Abutments

Bridges and piers

Towers

Nuclear power stations

Tall buildings

Operation

The Pendulum Readout uses two highresolution linear array CCDs (charge coupled device) as the basic sensors. Two collimated light sources at 90° to each other are directed onto two photo-sensitive CCD screens. The shadow of the pendulum wire falls on the CCD sensors and an automatically generated scan of the CCD pixel map records and digitally stores the coordinates of the shadow in the built-in computer.

This information is then converted to an analog signal that enables the position of the pendulum wire to be displayed locally in tenths of millimeter units on two LED panels mounted in the console. 

The signal can also be transmitted via 4-20 mA output or RS-485 output to a remote readout site.
