Introduction

Strain gages must sometimes be installed in areas where it is impossible, or at least very difficult, to attach leadwires after gage bonding. Examples include:

• Deep holes or recesses where gage tabs cannot be reached with a soldering iron.
• Poor-heat-conducting materials such as plastics, where soldering heat may damage the gage or specimen.
• Explosive or inflammable environments where appliances such as soldering irons are not permitted.

Under these and similar conditions, attaching leadwires to the gage before bonding will greatly simplify gage installation. This publication outlines recommended procedures. The various installation accessories referred to throughout this publication are Micro-Measurements M-LINE Accessories and available directly from the Vishay Measurements Group.
