  The working principle of shear beam load cell

  The shear beam load cell is widely used in places where operators need to measure pressure. The core component of the shear beam load cell is the spring element. The element is a piece of metal that deforms elastically under load and returns to its original shape immediately after the load is removed. This deformation or strain is absorbed by a strain gauge mounted on the metal element and converted into an electrical signal. The shear beam load cell can be calibrated for various weight units (grams, kilograms, or tons).

  Application of shear beam load cell

  Single-ended shear beams are mainly used for medium loads up to 5 tons. These load cells can be used in many medium-weight conveyor scales, container scales, and platform scales, as well as packaging and bottling plants. The scale sensor is also used to measure the force and torque in the factory. Platform scales are usually equipped with multiple load cells connected in parallel.

  Technical data

  Since shear beam load cells are commonly used in industrial applications, they have a sturdy design. This is also reflected in their IP67 or IP68 degree of protection, which means they are protected from dust, splash water, and even immersion. The datasheet of the shear beam load cell lists the key parameters of rated load and ultimate load or breaking load. Also important is the division of the smallest scale, because it determines the allowable tare weight. The shear beam load cell can be easily connected in parallel to a shared circuit, as the latest generation of these devices tends to calibrate the output current (by fine-tuning the impedance). Therefore, no additional trimming is required, and single-ended shear beams from different manufacturers can usually be combined into one loop.
