The load sensing element of the VH is a cylinder of high strength, heat-treated steel that withstands rough handling and loading. The local compressive strains induced in the cell by the tension in the anchor are measured by one to six vibrating wire sensors. The average of the strain readings from the sensors represents the mean load on the anchor, minimizing the effects of eccentric loading.

A steel housing with o-ring seals covers the cell and protects the strain gauges from mechanical damage and water infiltration. The load cell and connector are waterresistant. A plain jacketed cable links the load cell to a readout or data acquisition system. The cable exit is parallel to the surface of the steel housing to give better clearance. Centralizer bushings and load distribution plates are also available.

A thermistor incorporated into the gauge supplies information on the effects of temperature on the materials
