Load Cell Sensors

Load cell sensors are used to monitor weight and force.  

They are also known as; load cells, force sensors, weight sensors etc.  

Load cell sensors are available in many different types and configurations with various approvals and certifications.  

How Do Load Cell Sensors Work? 

Load cell sensors measure force and weight using strain gauges which are small and very sensitive sensors.  

Strain gauges can be found inside the sensor, they are bonded to the internal diaphragm and run-on electric currents. When the load cell sensor is under force or strain, the shape of the strain gauge will alter slightly, this will cause a change in the electric resistance. 

The change in output from the strain gauges is directly related to the force, load, or weight the load cell is measuring.  

Load Cells Sensor Applications 

Load cell sensors can be used for any application where weighing or force monitoring is required. For example; 

• Various types of scales  

• Weighbridges 

• On-board weighing applications  

• Tipper trucks  

• Medical equipment 

• Electrical transmission cables  

• Forklifts 

And many other applications. 

Load Cell Sensor Types 

There are many different types of load cell sensors available. Some of these are; 

Single Point Load Cells – the most common type of load cells. 

Tension and Compression Load Cells – for tension and compression applications. 

S-Type Load Cells – load cells in an ‘s’ shape for tension applications.  

Shear Beam and Bending Beam Load Cells – with a low profile construction.  

Pancake load cells – with super low profile.  

Onboard load cells – for measuring loads on heavy duty vehicles.  

Miniature and sub miniature load cells – for applications where space is restricted.
