ANCLO Anchor Load Cell: For Tensile or Compressive Loads

The load sensing element is a spool of high strength heat-treated steel or aluminum that withstands rough handling and loading. Electrical resistance strain gauges are bonded to the periphery of the spool. The gauges are mounted in a full bridge configuration that compensates for unevenly distributed loads. High resistance strain gauges are used to minimize cable effects. The load cells are compensated for temperature variations encountered during normal operations.

A steel housing with O-ring seals covers the spool and protects the strain gauges from mechanical damage and water infiltration. A plain PVC cable is wired directly to the cell or is connected via a detachable multi-pin connector. On large cells, the cable exit is parallel to the surface of the steel housing to give better clearance.

Installation

The surface against which the load cell bears should be smooth and perpendicular to the axis of the anchor or tieback. A seating pad comprised of a layer of mortar or concrete may be required. The use of a load bearing plate of suitable thickness between the base of the cell and the bearing surface is recommended. The load bearing plate, load cell, load distribution plate and anchor head assembly thread onto the anchor in sequence.
