Platinum-Tungsten Alloy Strain Gages
This unique, high gage factor (4+), strain gage series offers increased strain sensitivity (gage factor) more than double all other foil strain gage types. This feature is particularly useful in fatigue-rated load cells and transducers since strain levels can be reduced while still providing a standard 2 mv/V output. It is also helpful in dynamic (impact) transducers since normal transducer deflections can be reduced and dynamic response improved, while maintaining standard signal levels. This gage type also allows for higher burst protection in pressure transducers. Platinum-tungsten (Pt-W) gages are supplied with flexible polyimide backings, full encapsulation, and pre-formed solder dots. Fiber-reinforced backings are also available upon request.
