A load cell is a device which is used to measure heavy loads. It is basically a transducer which converts the force applied to it by the weight of an object into an electrical output which can then be accurately measured. Load cells are mainly used in industrial weight measurement. They have taken the place of mechanical lever scales which were once the industry standard for weight measurement.

 

Compression load cells are easily identified by its button design. They can easily used in tight places where space comes at a premium. As if that were not enough, they also have a great track record for their stability and long wear.

 

There are some instances where one would need to measure force in both directions, both in compression and in tension. This is where a Compression/Tension cell would be used. They have threaded ends so they can easily be integrated into position.

 

Another cell which can be used in compression and tension applications is the S-Beam cell. As you can guess, it gets its name from its shape. The S-Beam is the one you want for an accurate measurement of side load rejection. Truck scales and tank levels are ideal situations for this cell.

 

Tension link cells are used in applications where tension force needs to be measured. They are of particular use in hoists, cranes and other load bearing machinery. The tension on cables can be accurately measured with this cell, which lends its use to many applications.

 

Load cells can be categorized by their output, such as electric, pneumatic, and hydraulic. They can also be grouped by their detection methods, like compression, bending, shear and tension. They have revolutionized the way large amounts of force can be accurately measured, and are a great advancement over their lever scale predecessors.
