Introduction to the styles and corresponding characteristics of weighing sensors

Due to the different component constructions among different scales, the shape requirements of symmetric weight sensors vary. Therefore, sensor manufacturers have developed various styles of load cells to meet the usage needs of different scales. Common styles include: S-type load cells, single point load cells, cantilever beam load cells, spoke load cells, column load cells, and bridge load cells, Bellows weighing sensors, micro weighing sensors, etc. Next, we will briefly introduce the characteristics and applicable locations of these types of weighing sensors.

　　S-type load cell：

The S-type weighing sensor is composed of a parallel beam and an equal stress working beam, and the force is transmitted through the upper and lower and symmetrical auxiliary beams. Suitable for hook scales, electromechanical combination scales, hopper scales, material tank scales, packaging scales, ingredient weighing control, testing machines, and force monitoring and measurement.

　　Single point weighing sensor：

The single point load cell is based on the principle of parallelograms, but an additional center beam should be provided for the position of the strain gauge to complete the task of measuring the beams and deflections at the top and bottom of the parallelograms. Its advantage is that when the strain gauge leaves its position, it will be subjected to the torsional effect of eccentric load, while increasing the rigidity of the structure. Single point weighing sensors are suitable for industrial weighing and production process weighing such as automatic axle load scales, unmanned retail cabinets, electronic pricing scales, and small platform scales.

　　Cantilever beam weighing sensor：

A cantilever beam weighing sensor has a fixed bracket at one end that does not produce axial and vertical displacement and rotation, and a free end at the other end. In stress analysis of engineering mechanics, a typical simplified model is used. In practical engineering analysis, most actual engineering components can be simplified as cantilever beams. Suitable for ground scales, platform scales, and leather belts.

　　Spoke type weighing sensor：

The spoke type weighing sensor is composed of a wheel cluster, a wheel hub, a wheel spoke, and a strain gauge. The spokes are connected in pairs between the wheel hub and the wheel hub, and can be four or eight spokes. Suitable for weighing equipment such as weighbridges and platform scales, as well as for tension machines, press machines, and other force detection equipment.

　　Column type weighing sensor：

The column type weighing sensor is a double spherical automatic reset and corrugated flat diaphragm welded sealing structure, which can be used to measure pressure and is particularly suitable for heavy-duty applications. The large capacity nature of the design generally does not bend or deform unless improperly loaded. The column type weighing sensor is suitable for ladle scales, rolling force measurement, testing machines, and various large tonnage ingredient weighing control.
