Operation

The Magnetic Extensometer System is installed at locations where monitoring of settlement or heave is required. This System comprises a probe, a graduated tape on a reel and an access pipe along which magnetic targets are positioned at pre-determined

intervals. The reed switches within the probe detect the magnets as it moves along the length access pipe.

When a magnet is detected, the switch circuit closes causing a light to display and a buzzer to sound at the reel.
