Optical Strain Gage Installation Guide
Accurate strain measurement requires that the surface temperature of the specimen be measured as close to the strain gage as possible. The os3155 facilitates this by incorporating a built-in temperature compensation FBG. In addition, accurate measurement requires that the Stain gage, temperature compensator, and test specimen surface be at or near the same temperature.A layer of insulation over the sensor will help to reduce the temperature variations between these elements. A light colored or reflective surface will also help in situations where the gage will be exposed to direct sunlight.
For reliable operation it is essential that the installed gage be protected from physical damage, moisture, and corrosion. Various methods may be used to protect the installed gage depending on the application.This document outlines atypical protection method utilizing a waterproof seal and stainless steel cover.
