KISS principle for attaching leads to high temperature strain gages.

In this video, Steven demonstrates a new method for attaching leads to high temperature free-filament wire strain gage.

The high temperature gages are optimized for a wide variety of hostile environment applications, including geothermal measuring equipment, turbine engine control, and environmental test chambers in military, industrial, automotive, and down-hole drilling systems. Many analog circuits in these applications require components such as strain gages capable of surviving temperatures up to 2100°F (1150°C).

Strain gages are the passive building blocks for all strain measurement systems; and devices utilizing foil technology provide unmatched control over grid element design for specific applications. To achieve the best results, the right accessories are essential – from installation materials to conditioning systems. When an application requires strain measurements at temperatures above +700° F (+400°C), Micro-Measurements strain gages and accessories have all the right attributes.

The method of attaching leads is applicable to all the free-filament strain gages. Lead wire options include spot-welded Nichrome V ribbon in widths of 1.6 mm and 3.2 mm and with thicknesses of 0.05 mm and 0.08 mm, respectively.

To facilitate for attaching the wires, the Model 700 Portable Strain Gage Welding/Soldering unit enables capacitive discharge welding and features an onboard soldering pencil for lead wire attachment. The Model 700 includes a charging unit and can be placed in a backpack to free up technicians' hands.
