The sensor is used to determine the mass: the gravity exerted by the sample is converted into an electrical signal by the weighing sensor. Therefore, the load cell is a component of the electronic scale.

A widely used technology is based on the strain gauge technology: the analog weighing sensor consists of a measuring element (so-called spring body) made of steel or aluminum, on which the strain gauge (Wheatstone bridge) is installed. Each electronic scale has an integrated load cell to ensure that the weight can be measured.

Strain gauge weighing sensors are widely used, but there are other weighing technologies, such as electromagnetic force compensation technology EMFC, whose mass determination is completely carried out without friction loss. Usually, load cells are installed in factories, such as filling plants, weighing tanks, determining the filling amount, etc.

What types of sensors are there?

There are many different types of load cells, depending on their design purposes. Bending beam or shearing beam load cells are usually used for platform scales and the like. The pressure load cell is usually installed under the structure (container, silo, etc.), which bears heavy objects from above and is usually designed for higher loads. On the other hand, for a pull-type load cell, a weight is connected to the load cell. Load cell is an important part of platform scale and platform scale.

How does the sensor work?

Although the material of elastomer is stable, it also has little elasticity. This means that when a weight is placed on the scale, the force will act on the elastic body. The word elastomer originally comes from the fact that this material is slightly deformed due to this effect, but once no force is applied to it, it will return to its original shape, that is, "elasticity". This is the elastic deformation of the measuring element.
