Different types of load cells usually take variety of forms so as to fulfill their purpose in numerous industrial and research based applications. The majority of the load cells you find today mainly make use of strain gauge which acts as sensors. They function on certain operating principles depending on magnetostriction effect, elasticity and pressure of fluids.
The basic work of load cell includes converting force into electrical signals and they are often subject to “ringing”, whenever any type of abrupt changes in load takes place. They comprise of 4 strain gauges which are designed in the Wheatstone bridge configuration so as to fulfill the functionality of load cells. The conversion of force usually takes place in two stages via a mechanical arrangement, where force sensed deforms a strain gauge. The strain gauge then evaluates the formed deformation as electric signals as the strain formed changes the electric resistance capacity of the cable.
Tension load cells, also called as transducers, are appropriate for applications such as hanging scales, winching, lifting systems and crane weighing scales. These are made up of a rugged design for resistance to side loading. This kind of load cell provides high capacity weighing with superior accuracy. Many tension load cell manufacturer provide it openings at any one end to allow for easy connection to wire rope, shackles, D links or other rigging.
These transducers work on the principle of web tension measurement and any other tension measurement due to its reliable and accurate signal to controller or an indicator. Actual web tension will be easily measured by tension load cells in almost any moving web or filament. Normally, these are used in fiber processing, filament winding and materials’ applications which require tension control at very low levels. There are many tension load cell suppliers that offer a range of devices to suit your every need.
Load cells are available in a range of different sizes, shapes and capacities. Now, these are the industry standards for all kinds of weighing. Depending on the kind of cell, a load cell can made up one, two or four strain gauges. There are many load cell manufacturer in market, supplying different kinds of load cells such as single point, canister type, tension, pancake load cell, single ended shear beam, double ended shear beam, torsion ring, S type and wireless load cells to name a few.
The Pancake load cells are a compact and universal force sensor. There are many pancake load cell manufacturers which supply the load cell with stainless steel construction. This has a small outer diameter and is designed to measure both compression and tension with high accuracy. This versatile load cell’s shear web design gives high performance and provides high resistance to extraneous forces such as torsion, bending, and side loads. An optional load button is also provided by many pancake load cell supplier for compression only applications.
