Benefits of Hollow Load Cell

Load Cells have rugged and robust construction, along with outstanding reliability and long-term stability.

They are specially designed to suit harsh and severe industrial environments.

Load Cells are temperature compensated.

They feature a stable system with no moving parts or linkages.

Some models incorporate multiple strain gauges to reduce positioning effects.

Any standard strain gauge bridge measuring read-out device can be used with the load cells.

The load cells have negligible side load and eccentric load effects.

Principle of Hollow Load Cells

When we use load cells, one end is usually secured to a frame or base, while the other end is free to attach the weight or weight-bearing element.

When force is applied to the body of the load cell, it flexes slightly under the strain. This is similar to what happens to a fishing rod when a fisherman hooks a fish.

The fisherman will secure the rod in their hands while the fish applies a pulling force on the other end of the fishing line. The result of this force is that the fishing rod bends, with a bigger, stronger fish, causing the bend to be more extreme.

When this action happens to a load sensor, the deformation is very subtle and not visible to the naked eye. To measure the deformation, strain gages are tightly bonded to the body of the load cell at pre-determined points, causing them to deform in unison with the body. The resulting movement alters the electrical resistance of the strain gages in proportion to the amount of deformation caused by the applied load.

Using signal conditioning electronics, the electrical resistance of the strain gages can be measured with the resulting signal being output as a weight or force reading.

FAQ

Q: How accurate are load cells?

A: The accuracy of a load cell sensor is determined through its %RO. If a 10,000 kg load cell has an error of ± 0.5%RO, it means the best resolution of the load cell would be ±50Kg

Q: What is load cell sensitivity?

A: Load Cell Sensitivity is a very important factor for the instrument. A sensitivity of 3mV/V means that the load cell produces an output signal of 3mV at nominal force when the input voltage is 1V.

Q: What is load cell calibration?

A: Over time, load cells tend to age and misalign. Hence, there’s a need to calibrate them regularly. The comparison of actual load cell outputs against the test loads is known as calibration.

Q: What is the difference between a load cell and a strain gauge?

A: A strain gauge is a single transducer used to convert the mechanical deformation into readable electrical output. Whereas, a load cell comprises an array of strain gauges that convert the mechanical load into readable units.

Q: What is a primary axis?

A: The axis along which the load cell is designed to be loaded is known as the primary axis.

Q: What is Axial Load?

A: It is the load applied along the primary axis.

Q: What is non-linearity?

A: The difference between the output at a specific load and the corresponding point on the straight line drawn between minimum load and maximum load is termed Non-Linearity. It is usually expressed in units of %FS.

Q: What is non-repeatability?

A: The maximum difference between output readings for repeated loadings while keeping the loading and environmental conditions identical is known as Non-Repeatability. This was all about the Load Cells and their different types.
