Load cell amplifier
The board is total solution for
analog front end for Load Cell applications.This board is highly integrated in
the sense it contains Instrumentation Amplifier, Analog to Digital Converter and Digitizer which outputs serial data of 9600 baud rate for direct reading in
kilograms.
The output can be used to connect
to microcontroller for further display and processing or can be fed to PC
serial port to view on terminal.The calibration functions in built
in the board giving very accurate, stable and reliable output every time.
