Is there any difference between strain gauge & load cell.
Load cell datasheet: http://www.meas-spec.com/downloads/FC23.pdf
strain data: http://www.omega.com/techref/pdf/STRAIN_GAGE_TECHNICAL_DATA.pdf
If we look at datsheet of load cell it exactly says that at full rated load voltage will be 100mV. Full rated load is given exactly.
1. Strain gauge datasheet mentions only strain like 50000 micrstrain. How can I convert it into weight. What's is the weight when strain is 5000, 10000, microstrian. What is max weight in kg when 50000 microstrain occurs.
2. When we connect strain gauge in quarter bridge it gives output in change in voltage when strain gauge resistance change. Let say on 1 ohm change voltage change to 1mV. Now how to convert it into load in microcontroller code.
