I have used four half bridge strain gauge load sensors and connected them in a wheat-stone bridge configuration. I have fed the output of the sensors to the ADC (ADS1230) which is a 20 bit analog to digital converter.I have used ATMEGA16 microcontroller that takes the input from the ADC and displays to the LCD.
