Can’t utilize bonded strain gages? Then apply our easy to install high temperature weldable strain gages on your test article. HPI weldables have our wire-wound strain gages ceramic bonded to a high nickel shim for easy field installation. Cables are pre-wired so spot-welding and fine wire joining are no longer an issue. Time to install is greatly reduced and all facets of the sensor are factory tested for 100% success. Custom strain gage designs and cable options are all readily available.

Max Temp: 1800°F (980°C). HBWAH Weldable Strain Gages are constructed of an iron chrome aluminum alloy (Hoskins 875 ™) providing high resistivity and very good oxidation resistance. Recommended for high temperature static measurements where a compensating gage, a half bridge or full bridge configuration is used. -
Max Temp: 1600°F (871°C). HBWANV Strain Gages are configured with a Nichrome wire sensor bonded to a Hastelloy® X shim using flame sprayed alumina. These fatigue resistant gages are commonly used to measure vibratory strain in extreme high temperature environments on test components for automotive, aerospace and power generation applications. -
Max Temp: 1900°F (1038°C). HBWAPT Series strain gages are constructed with a platinum-tungsten alloy that has excellent high temperature oxidation resistance, and low, stable temperature coefficients of resistance. These high temperature strain gauges are an excellent choice to measure the stress distribution and fatigue life of turbine blades in rapidly rotating turbo jet engines. Other uses include test and failure analysis in many automotive and aerospace applications.
