An electronic auxanometer for field use.

Hari J., Hari P., Kanninen M. (1978). An electronic auxanometer for field use. Silva Fennica vol. 12 no. 4 article id 5012. https://doi.org/10.14214/sf.a14866

Abstract

This paper describes the design and functioning of an electronic auxanometer designed for field use, and some results obtained with it. The changes in stem radius are monitored with a micrometer screw turned by an electirc motor. A potentiometer transforms the position of the screw into an electronic signal, which is recorded. The accuracy of the device is approximately 1–2 μm. Field experiments with the auxanometer are described and discussed. The accuracy of the device was found to be sufficient for measuring hourly changes in stem radius.

The PDF includes a summary in Finnish.
