Load cells and force sensors
On this page you will find a lot of information about load cells. If you have any questions, we at Zemic Europe will be happy to help. Please feel free to contact us.
The heart of any weighing or measuring system is the load cell. A load cell is an electrical instrument which is used to convert a mechanical force into an electrical output signal. You will need load cells and force sensors in basically any application where forces or weights need to be measured or monitored.
In the weighing industry various kinds of loadcells can be used for the detection of Grams, Kilograms, Tons, Pounds, Ounces, Newton, Kilonewton etc.
What are load cells and force sensors?
Load cells are highly accurate transducers. Load cells are designed to sense force or weight under a wide range of conditions. They are not only the most essential part of an electronic weighing system, but also the most vulnerable.
In order to get the most benefit from the load cell, the user must have a thorough understanding of the technology, construction and operation of this unique device. In addition, it is important to select the correct load cell for the application. We are ready to help you with all questions concerning force measurement. The general terminology for load cells can be found in the OIML R60 regulation for load cells.
How does a load cell work?
All load cells we offer at Zemic Europe, are based on the strain gauge principle. We focus on strain gauge load cells with analogue and digital output signals. Zemic glues strain gauges on force sensor elements. The strain gauges are located on the weakest part of the element. By putting force on the element, it will deflect on this exact spot. By the deflection of the element the strain gauge will be stretched or compressed.
The ability to weigh with a load cell depends primarily on its ability to deflect / bend repeatably when load is applied or removed.
Knowing this, it can be very useful to install mechanical overload stops in an application. In our blog “how to interpret deflection of load cells for overload protection” you can see two examples. One mechanical stop is installed below our BM11 bending beam. In the second picture you will see a rather simple solution of installing a screw under our BM8D shear beam load cell.
What kind of load cells are available?
Zemicis a leading manufacturer and designer of loadcells. We offer a full range of loadcells. We have the following types of load cells available:

How to install load cells?
Once the correct load cell has been selected, it is very important to install the load cell correctly in your application.
By doing this, the maximum accuracy and working life of the load cell can be achieved.
Zemic Europe offers accessories for most of the different load cells. We advise to use these accessories for a proper installation of the load cell.
Please read our blog here: How to install load cells?
Besides choosing the right accessories, it is also important to make a proper load cell calibration.
