Modern weighing systems often place material handling equipment such as conveyors, weigh hoppers, or part holding fixturing, right on the weighing platform. This "Dead Load" can use up most of the active range of traditional scales or balances. This severely limits sensitivity and accuracy.

The Counter-Balanced Weigh-Cell negates the effect of the Dead Load. In simple terms, the Counter-Balanced Weigh-Cell works like a childs SEESAW, The Load-Cell is mounted at the center of the unit. Mass may be placed at both ends of the assembly to mechanically maintain a Zero Output. This leaves the full range of the Load-Cell for the item being weighed.


The AWS weigh cell may be used with fixturing such as a platter, hopper or conveyor mounted directly upon it. The weigh cell uses counterbalance weights to off-set the weight of this fixturing.

This feature means that the entire live range of the weigh cell is available for the object being weighed. This allows much greater resolution and accuracy than other types of scales.


Mass Balance is a further refinement of the concept of Counterbalance. The primary benefits are Increased Accuracy and Immunity to External Vibration.

The Mass Balanced weigh cell not only subtracts out the weight of fixturing. It also balances most of the weight of the object to be weighed, allowing for the use of an even lighter capacity weigh cell.

The weighing system reports the weight as it varies from an ideal or master weight. This provides the finest degree of accuracy available.


Mass Balance requires the use of a heavier Counterbalance Weight. The *Counterbalance Weight should be approximately 2 pounds heavier than the TOTAL weight of the fixturing PLUS the weight of an ideal part (object to be weighed).

Install the fixturing on the weigh cell. Place a master weight (ideal part) on the fixturing. Install the Counterbalance Weight according to the weigh cell instruction manual.

Slide the weight toward the front or back as necessary to achieve a ZERO reading on the meter.

*Consult factory to obtain additional Counterbalance Weights.
