FABRICATION OF DYNAMIC WEIGHT BRIDGE
Mechanical engineering without production and manufacturing is
meaningless and inseparable. Production and manufacturing process
deals with conversion of raw materials inputs to finished products as
per required dimensions specifications and efficiently using recent
Weight bridge is system which is used to calculate the load of
the vehicle in a static place, but it is a static one, so every vehicle are
need to come weight to find out out the weight of the vehicle, in our
project weight bridge is a dynamic one here, we can move the
weight bridge where the vehicle or component
It has a platform under the platform the load cell is fixed. A
load cell is a transducer that is used to convert a force into electrical
signal. This conversion is indirect and happens in two stages.
Through a mechanical arrangement, the force being sensed deforms
a strain gauge.
The strain gauge measures the deformation (strain) as an
electrical signal, because the strain changes the effective electrical
resistance of the wire. A load cell usually consists of four strain
gauges in a Wheatstone bridge configuration.
Load cells of one strain gauge (quarter bridge) or two strain
gauges (half bridge) are also available. The
electrical signal output is typically in the order of a few millvolts
and requires amplification by an instrumentation amplifier before it
can be used.
The output of the transducer is plugged into an algorithm to
calculate the force applied to the transducer.
1) Accuracy is more
2) No errors in digital
3) It is a portable and handy
4) It can withstand all climatic condition
5) Mechanical failure chances is very low
1) Electronic reliability is low compare than mechanical
2) Cost of load cell is high
