Shielded Foil Strain Gages
The KFSB series foil strain gages are shielded by copper foil covering the whole body. Thus, if a large current flows to or around the gage bonding site, noise will be prevented from entering the measuring circuit.
|Materials Resistive element||CuNi alloy foil (120 Ω)
NiCr alloy foil (350 Ω)
|Operating temperature in combination with major adhesives after curing (°C)||CC-33A: -196 to 120ºC
EP-340: -55 to 120ºC
|Operating temperature in combination with major leadwire cables (°C)||Vinyl-coated normal-temperature low-noise 3-wire cable (L-13): -10 to 80ºC|
|Self-temperature-compensation (°C)||10 to 100ºC|
|Applicable linear expansion coefficients (×10-6/℃)||11, 16, 23|
|Strain limits at normal temp. (approx. %)||0.5|
|Fatigue lives at normal temp. (times)||1x104 (±1500μm/m)|
When ordering, suffix the lead-wire cable code to the model number with a space in between.
KFSB-5-120-J1-11 with a vinyl-coated normal-temperature low-noise 3-wire cable 5 m long pre-attached
→ KFSB-5-120-J1-11 J5M3
If no lead-wire cable code is suffixed, the gage is delivered with 2 polyester-coated copper wires 25 mm long each.
