Description
A load cell is a transducer that converts force into measurable electrical output.
This straight bar load cell (sometimes called a strain gauge) can convert pressure (force) into an electrical signal. Load cells are specially shaped metal parts that have strain gauges glued to them. The strain gauges are resistors that change their resistance when they are bent. When the metal part bends, the resistance of the load cell changes
Load cells generally consist of a spring element on which strain gauges have been placed. The spring element is usually made of steel or aluminum. That means it is very sturdy but also minimally elastic. As the name "spring element" suggests, the steel is slightly deformed under load, but then returns to its starting position, responding elastically to every load. These extremely small changes can be acquired with strain gauges. Then finally, the deformation of the strain gauge is interpreted by analysis electronics to determine the weight.
Each straight bar load cell is made from an Alloy Steel and is capable of reading capacity up to 50Kg.
Additionally, these load cells offer an IP65 protection rating.
There are many varieties of load cells like Compression/Tension Load Cells, S-Beam Load Cells, Bending Beam Load Cells, Platform, and Single Point Load Cells, Canister Load Cells, Low Profile Load Cells, etc.
The method of operation can involve either the use of a weight balancing mechanism or the detection of the force developed by mechanical levers.
Load cell designs can be distinguished according to the type of output signal generated (pneumatic, hydraulic, electric) or according to the way they detect weight. (bending, shear, compression, tension, etc.)
The recommended operating voltage is 5V and it can work maximum at 10V.
