It is VITAL that personnel responsible for the installation and
use of the Geosense® Hydraulic Load Cells READS and
UNDERSTANDS the manual, prior to working with the
equipment.
1.1 General Description
The primary uses for the
Geosense
®
HLC
-
6000 Series Hydraulic Anchor Load
Cells
are used for measuring loads acting on:
-
•
Ground Anchors
•
Rock bolts
•
Tie backs
Particular features of the
Geosense
®
HLC
-
6000 Series Hydraulic Anchor Load
Cells
are:
-
•
Robust stainless steel construction
•
Accommodates some eccentric loading
•
Reliable long term performance
•
Rugged, suitable for demanding environments
•
High accuracy
•
Data logger compatible
They
consist of a sensitive pressure pad formed by joining two stiff steel discs at their
periphery. The void inside the cell is filled with de
-
aired fluid. When load is applied to the
cell the pressure of the inside liquid changes. The changes in pressure correspond
directly to the load applied.
Manufactured with a centre hole to accommodate anchors, rock bolts and tendons.
The pressure in the loads cell is measured either by a manometer or a vibrating wire
transducer (VWDT
-
5000) which are available in the following models:
HLC
-
6000
-
Manometer (scale in bar
for pressure indication)
HLC
-
6500
-
Vibrating wire transducer
