According to function request for paper thickness measuring control system

adopt β-ray absorption principle

design of a kind of intelligent paper thickness gauge is achieved. It takes MSP430FG479 as the microprocessor

with CAN and RS—485 communication interface

it has also self inspection and self calibration function. Realization method of the system hardware

and software design process are given. Experiment verifies that the precision achieve over 0. 1 %. The design scheme can be used to detect thickness of all kinds of paper and board by using different radiate source

easy operation and stable work.
