An adoptation of an existing concept for monitoring soild strains using a basic and economical system--the common methaletector, is presented. This unit electronically utilizes a beat frequency oscillator system. Instead of an audible signal output, the new soil strain gage used an additional amplifier and a frequency counter for a quantifiable output. As the soil between the embedded transducer is subjected to strain, the beat frequency changes and is recorded. For approximately $300 a portable, easy-to-use, and relatively inexpensive soil strain gage can be made for monitoring in-situ deformation situations.
