Why load cells are used?
A load cell is a type of transducer which is used to convert mechanical force into a measurable electrical output, anything which needs to be weighed probably uses a load cell to do so. Load cells come in many different shapes and sizes so that they can be added to different machinery and weighing equipment.
What are the types of load cells?
When classified by the direction of load detection, load cells can be divided into the following types: tension, compression, alternating, and bending. Based on precision, load cells can be classified as ultra precision, precision, standard, and general-purpose.
What is the working principle of a strain gauge load cell?
Principle of Strain gauge load cell On this cylinder, if the strain gauges are bonded, the strain gauge also is stretched or compressed, causing a change in its length and diameter. This change in dimension of the strain gauge causes its resistance to change.
What is mV V in load cell?
A load cell (or loadcell) is a transducer which converts force or mass into a measurable electrical output, most commonly stated as ## milli volt per volt (mV/V). Although there are many varieties of force sensors such as hydraulic, piezo and pneumatic strain gauge based load cells are the most commonly used type.
Where is load cell applicable?
Load cells belong to class C and D. Class C load cells are applicable in mechanical engineering and civil engineering. Class D load cells are useful to weigh produces like vegetables, meat, consumer goods, etc. Nowadays, class C strain gauges are also used for weighing produces.
What is load cell sensitivity?
Load cell sensitivity refers to the smallest force a pair of load cells can reliably detect. The greater a load cell’s sensitivity, the better a load cell is at detecting the slightest changes in tension. Resolution refers to the load cell’s ability to produce an output relative to the detected change.
What is load cell capacity?
A load cell converts force or weight into an electrical signal, which can then be sent to a remote computer or recorder to monitor load, pressure, strain and more.
