Center-Hole Load Cell

Brand : Slope Indicator – USA

Applications :

Center-hole load cells are designed to measure loads in tiebacks, rock bolts, and cables. Applications for these load cells include:
• Proof testing and long-term performance monitoring of tiebacks, rock bolts, and other anchor systems.
• Monitoring loading of vertical supports in underground openings.

Operation
The load-bearing element of the load cell is a spool of heat-treated steel alloy. Four or more strain gauge rosettes are bonded to the spool. Each rosette consists of two strain gauges, one oriented to measure axial strain; the other oriented to measure tangential strain. The rosettes are spaced evenly around the periphery of the spool and are
wired together to provide a single output.

The strain gauge rosettes are protected from moisture and impact damage by a strong aluminum housing
filled with a high-density resin.
For best results, the load cell is centered on the bar and bearing plates are placed above and below the cell.
Bearing plates must be able to distribute the load without bending or yielding.

Advantages
Single Reading: The outputs of the strain gauges are integrated into a single reading, eliminating the switch
box, multiple readings, and averaging normally associated with other types of center-hole load cells.
Easy Centering: Centralizers keep the load cell centered on the bar, bolt, or cable.
Manual or Automatic Readout:
Load cells are read manually with a portable readout or automatically with a data logger.
