Load Cell Operating Principle


Load cell is a sensor or a transducer that converts a load or force acting on it into an electronic signal. This electronic signal can be a voltage change, current change or frequency change depending on the type of load cell and circuitry used.

When a load is applied, the body of the load cell deforms slightly and experiences deflection. Deflection refers to the change of length of the load cell along the primary axis when a load is applied.

 

In a compression load cell, the deflection causes the gauge to become shorter and thicker.

In a tension load cell, the gauge is stretched and becomes longer and thinner.

In response to the body shape changes, the strain gauges also change shape.

This, in turn, causes a change in the electrical resistance of the strain gauge which can then be measured as a voltage change. Since this change in output is proportional to the amount of weight applied, the weight of the object can then be determined from the change in voltage.
