Foil Strain Gages for Composite Materials KFRPB series

Model: KFRPB-2-120-C1-9 L5M3R

KYOWA KFRPB Foil Strain Gages for Composite Materials. These strain gages are suitable for measuring strain in compound materials such as CFRP and GFRP. They make use of a special pattern to improve the effect of self heating caused by gage current as well as the reinforcement effect on low- elastic materials. The KYOWA KFRPB-2-120-C1-9-L5M3R is a foil strain gauge designed specifically for measuring strain on composite materials such as CFRP (Carbon Fiber Reinforced Plastic) and GFRP (Glass Fiber Reinforced Plastic). This model features a specialized gauge pattern that minimizes self-heating and the reinforcement effect on low-elasticity materials.

• Series (KFRPB): Self-temperature-compensation (SELCOM) gauges optimized for composites.
• Gauge Length (2): 2mm active gauge length.
• Resistance (120): 120 ohms nominal resistance.
• Grid Style (C1): Uniaxial configuration.
• Linear Expansion Coefficient (9): Compensated for materials with a coefficient of approximately 9 × 10⁻⁶/°C.
• Lead-Wire Cable (L5M3R):
  • L: Vinyl-coated flat cable.
  • 5M: 5 meters in length.
  • 3R: 3-wire system with a ribbon-style connection.
• Operating Temperature: When used with vinyl-coated flat cables, the operating temperature range is typically -10 to 80°C.
• Self-Temperature-Compensation: The compensated temperature range is between 0 and 150°C.
• Strain Limit: Approximately 2.2% at room temperature.
• Fatigue Life: Capable of approximately 1 x 10⁶ cycles at ±1500 μm/m.

How to order

When ordering, specify the model of the strain gage and the code of the lead-wire cable with a space in between. E.g. KFRPB-5-120-C1-1 with 2 polyester-coated copper wires 15 cm long→ KFRPB-5-120-C1-1 N15C2 KFRPB-5-120-D22-3 with a vinyl-coated flat 3-wire cable 5 m long pre-attached→ KFRPB-5-120-D22-3 L5M3S If no lead-wire cable code is suffixed, the gage is delivered with gage leads only. (Silver-covered copper wires 25 mm long) *10 gages/pkg

• Target Materials: These strain gages are specifically designed for use with composite materials, particularly CFRP and GFRP.
• Measurement Type: They are used to detect mechanical strain (elongation or shrinkage) in structures, which helps in determining the stress applied to the material and confirming structural safety and strength.
• Self-Temperature Compensation: The KFRPB series are self-temperature-compensation (SEMIKI) gages, meaning their design minimizes the effect of temperature changes on the strain readings.
• Special Gage Pattern: The unique pattern of the foil minimizes two potential sources of error in measurements:
  • The effect of self-heating caused by the gage current.
  • The effect of the gage’s reinforcement on low-elasticity materials.
• Applications: Beyond general testing, strain gages in general are used across various fields including machinery, automotive, civil engineering, and research to measure force, pressure, acceleration, and torque. The KFRPB series is used in applications where composite materials are utilized, enabling evaluation of their mechanical and temperature characteristics.
