Weighing transducers are used in different applications to measure force or weight. We can adopt strain gauge and Wheatstone bridge theory and use them to construct weighing transducer. When the weight is placed above the line, the length of the line will decrease. This line will also be "fat", or prominent.
The weighing transducer we made has the resistance value representing our four strain gauges. Because in our weighing transducer, the resistance of all strain gauges is the same. Using Ohm's law, we configure the pressure drop at points 1 and 2. Each branch contains 350Ω + 350Ω = 700Ω resistance. The current in the branch and the branch voltage divided by the branch resistance
Advantages of weighing transducer:
Not sensitive to temperature changes
They contain no fluid, so if the diaphragm ruptures, it will not contaminate the process.
The weighing transducer of a voltmeter can be used for expansion and compression.
Strain gauge weighing transducer has low cost, so it is mainly used in industry
