Measuring Anchors

Measuring Anchors

Combine a rock bolt and an extensometer and are used to determine load exerted on rock bolts.
Within an anchor body, four mini extensometer rods have anchor points at different locations. Changes of length or compression between each anchor point can be measured using a mechanical dial gauge, VW, transducer or potentiometer.

Features:

-Simple & robust construction
-Replaces system anchor
-No extra borehole required
-Automatic data acquisition possible
