High-temperature Foil Strain Gages (350ºC)
The metal base enables easy mounting with a compact spot welder.
|Materials Resistive element||NiCr alloy foil|
|Materials Base||Stainless steel|
|Operating temperature in combination with major adhesives after curing (°C)||(Spot welding) -50 to 350ºC|
|Operating temperature in combination with major leadwire cables (°C)||Glass-coated Ni-plated 3-wire copper cable: -50 to 350ºC|
|Self-temperature-compensation (°C)||10 to 300ºC|
|Applicable linear expansion coefficients (×10-6/℃)||11, 16|
|Strain limits at normal temp. (approx. %)||0.5|
|Fatigue lives at normal temp. (times)||1x107 (±500μm/m)|
When ordering, suffix the lead-wire cable code to the model number with a space in between.
For the gage with a glass-coated Ni-plated 3-wire copper cable 5 m long pre-attached
→ KH-5-350-G4-11 D5M3
If no lead-wire cable code is suffixed, the gage is delivered with an advance ribbon cable only (25 mm long).
