What Is The Function Of Electronic Weighing Machine
Digital scales work with the use of a strain gauge load cell.
Whereas analog scales use springs to indicate the weight of an object, digital
scales convert the force of a weight to an electric signal. Electronic
Weighing Machine In Jogeshwari will
provide components consist of a strain gauge, a device used to measure the
strain of an object, and a load cell sensor, an electronic device used to convert
a force into an electrical signal. A load cell is also known as a force
transducer.
When an item is placed on the scale, the weight is first evenly
distributed. Under the flat tray of a digital scale. The mechanical design of
the digital scale then applies the force of the weight to one end of a load
cell. As the weight is applied, that end of the load cell bends downwards. The
force of weight then deforms the strain gauge.
The strain gauge can consist of metal tracks, or foil, bonded to
a printed circuit board or another backing. When the metal foil is strained, the
backing flexes or stretches. The strain gauge then converts the deformation to
an electrical signal.
Because the load cell has an electric charge, as it moves
downwards, the electrical resistance changes. The resulting small change in
resistance becomes an electrical signal. The signal is run through an analog to
digital converter and then passes through a microchip that
"translates" the data. As a result of this final calculation, numbers
indicating the weight of the object appear on the LCD display of the digital
scale.
The main difference between an analog weighing machine and
an Electronic
Weighing Machine In Jogeshwari is that the
analog weighing scale uses springs, needle and a metre to indicate the weight.
On the other hand, a digital weighing machine uses a digital screen to show the
readings. A digital weighing machine is more easy to use since it shows the exact
weight in numbers rather than a needle which keeps moving constantly.
