![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.[citation needed] 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.
Advantages
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
Disadvantages
1) Electronic reliability is low compare than mechanical
2) Cost of load cell is high](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

Production and manufacturing process deals with conversion of raw materials inputs to finished products as per required dimensions specifications and efficiently using recent technology 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.
