Most load cells use a strain gauge to detect measurements, but hydraulic and pneumatic load cells are also available. Load cells come in many different shapes and sizes so that they can be added to different machinery and weighing equipment. And, when the length and cross-section of the strain gauge changes, its electrical resistivity also gets altered, thereby changing the output voltage. WORKING PRINCIPLE OF SHEAR BEAM LOAD CELL. The Shear Beam Load Cell The strain gauges are bonded to a reduced part of the cross section of the beam in order to maximise the shear effect. Beam load cells, like all other modern load cells, are essentially transducers that convert force or weight into an electrical signal by way of strain gauges. Posted on August 19, 2020 by Sandra. The shear beam capacities are from 100kg to 50t. When a load is applied, the body of the load cell will flex due to the elastic properties of the metal material that it is made from. If the load cell deforms, the gauge changes in shape, causing the change in electrical resistance of gauge, which in turn measures voltage. Further to this, it is common to see beam load cells split into two subcategories, depending on the way they measure the force or weight. A recess is machined in each side of the load cell, leaving a relatively thin vertical web in the centre. This contrasts some of the column-like compression load cells, which often have the reverse ratio, being narrower than they are tall. Beam load cells represent the largest and most versatile group of load cells, covering an extensive range of possible capacities, diverse mounting options and accessories. They are often used in combination in larger weighing equipment and scales when the use of a single-point cell becomes impossible. The bending beam does not have a reduced cross-section for the strain gauges, rather this beam is machined all the way through. What is a tension load cell, and how does it work? One end of the shear beam contains the mounting holes while the opposite end is where the cell is loaded. This effect is proportional to the initial force or weight, allowing it to be calculated. Load cell is a sensor or a transducer that converts a load or force acting on it into an electronic signal. They are arguably the most common type of load cell in use today. Reference : 5510.
