abstract A device was developed for the continuous monitoring of the expansion of straw or hay briquettes after removal from the die. The instrument was tested within a trial of briquetting of various straws submitted for mechanical and chemical pre-treatments. The deve-loped device proved to be easy to use, while allowing measurement sensitivity better than 0.5 mm over a long period of time. It was possible to record even slight briquette expansion and to determine different trends of expansion for wheat and rice straw and for straws that had undergone different treatment.
