Micro-Measurements High-Temperature Weldable Strain Gauges

Vishay Micro-Measurements high-temperature weldable strain gauges are free-filament wire strain gages pre-bonded to shim stock using flame sprayed alumina. The gauges can be welded to the test structure using a capacitive discharge spot welder (such as Vishay Micro-Measurements Model 700), permitting easy installation in the field, especially on large structures.

High-temperature weldable strain gauges are excellent in applications where protection against moisture is not required. The fatigue resistance of this bonded wire strain gauge makes it the best choice for dynamic, impact or vibratory strain measurements to 1800°F [980°C]. Their use in measuring static strains should be avoided. High-temperature weldable strain gages are available with grids of Nichrome V or Pt8W alloys. They can be ordered with either of two types of pre-attached high-temperature insulated cable.
