| The SM-2 Series of miniature vibrating wire strain gauges is used to measure variations in strain, which allows stress evaluation when the material's modulus of elasticity is known.
The SM-2 is offered in two models, the SM-2W and the SM-2A, which both differ in their installation. The SM-2W is designed to be spot-welded on a surface and then covered by a protective housing which contains the electromagnet. The SM-2A is generally installed inside a small diameter borehole. Its electromagnet surrounds the connecting tube. |
