Understanding the Mechanism and Application of a Beam Load Cell

 

Load cells come in different varieties with a specific application. Each is used for specific mechanisms and has a respective force capacity that it can endure. For instance, a compression load cell can bear up to 50 tons of weight, while the capacity for an S-type load cell is from 25 kgs to 30 tons. It’s all about deciphering even the minutest of differences in calibration, which demands the fore transducer to be accurate in its application every single time.

For this blog, we will discuss in detail the function and operational principle of a beam load cell.

What is a beam load cell?

Beam load cells are widely used across multiple applications in different industries, especially in the weighing industry. Other similar varieties of load cells available at load cell suppliers are:

- Compression load cell.

- Single point load cell.

- Tension load cell.

These are the common types of load cells used these days. They operate in the form of cantilevers, which seamlessly flex marginally when confronted by force or weight. The beam cell remains fixed on one end and remains free on the other end. However, there are double-ended designs available these days. Those are placed at each end and are loaded at the center, like a hammock.

The beam load cells are subdivided into two categories, based on the mechanism of measuring weight or enduring force.

- The bending beam cells are used to measure the level of the bending distortion;

- The shear beam load cell is used to measure the level of shear distortion.

Beam load cells fall under the most versatile category of load cells that can bear an extensive range of load capacities for varied applications. They have different mounting options, calibration points, and a host of accessories across diverse applications in major industries. Other than single point use, load beam cells are also used combined with other load cell varieties to endure larger load capacity in complex weighing equipment.

What is the working principle of the beam load cell?

Like any other load cells, the beam load cell acts as the part of a transducer that converts the weight or force using strain gauges into an electrical signal. Here’s a brief rundown of the working principle:

- When the weight or force is exerted on the beam load cell, the body flexes influenced by its inherent elasticity contributed by the metal fabrication.

- The strain gauges are attached to the load cell with strategic positioning, remaining secured to the load cell surface.

- The strain gauges either stretch or compress along with the main body of the load cell.

- The force alters the electrical resistance of the load cell, leading to a change of the circuit voltage.

- The effect remains proportionate to the initial weight/force exerted on the load cell, enabling calculation of the same.
