پروژه با Loadcell Sensor 5KG
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. Each load cell is able to
measure the electrical resistance that changes in response to and
proportional to the strain (e.g. pressure or force) applied to the bar.
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 aluminum alloy and is capable of reading a
capacity of 1Kg/2Kg/3Kg/5Kg/10Kg/20Kg. These load cells have four strain
gauges that are hooked up in a Wheatstone bridge formation.
Additionally, these load cells offer an IP65 protection rating and
feature two M5 sized through-holes for mounting purposes.
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.)
