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.

Maximum operating temperature at sensor: 1600°F (871°C)
Strain Type: Dynamic
Gage Resistance (nominal): 120 Ohms
Gage Factor (nominal): 2.0

Maximum operating temperature at cable:
(FG) Fiberglass Insulated – 900°F (482°C)
(MG) Mineral Insulated/Inconel Jacket – 1800°F (980°C)
(CB) Ceramic Braid Jacket – 1800°F (980°C)
