Strain Gauge N11-FA Series

Model: N11-FA-1-120-16-P4-VSE3

The Showa N11-FA-1-120-16-P4-VSE3 is a general-purpose, uniaxial foil strain gauge manufactured by Showa Measuring Instruments Co., Ltd.. It is designed for precise, single-direction stress and strain measurements on structures or components Measurement Type: Uniaxial (single-direction) static and dynamic strain testing. Gauge Factor: Approximately 1.9 to 2.0 (typical for the Showa N11 Series). Encapsulation: Laminated matrix protects the grid entirely from minor handling scratches and environmental moisture.

• Application Versatility: Suitable for both static and dynamic strain measurements on steel, aluminum, and small-grain concrete.
• Protection: The gauge grids are entirely protected by a laminated surface, making them easier to handle during installation.
• Self-Temperature Compensation: The “11” in the model name indicates the material code for self-temperature compensation, typically matched for steel with a coefficient of thermal expansion of 11 ppm/°C.

• N11: Series code denoting general-purpose foil strain gauges. Both sides of the grid are fully laminated for protection. 
• FA: Base material designation, typically referencing a thin, flexible polyester or epoxy backing sheet. 
• 1: Gauge length of 1.0 mm (the physical length of the sensitive grid area). 
• 120: Nominal resistance value of 120 Ohms.
• 16: Linear expansion coefficient tracking. This value (16 ppm/°C) indicates that the gauge is self-temperature-compensated for specific test materials, such as copper or stainless steel. 
• P4: Lead-wire configuration code, representing a specific type of pre-attached lead wire (e.g., ribbon or parallel wire format) to simplify installation. 
• VSE3: Lead-wire material and length specifier. Typically indicates a 3-meter vinyl-coated lead wire configuration optimized for standard 3-wire bridge measurement connections

• • Stainless Steel Structural Testing: The "16" in the model code means it is self-temperature-compensated for materials with a thermal expansion coefficient of 16 ppm/°C. This matches stainless steel (like SUS304 or SUS316), preventing temperature fluctuations from ruining your strain data.
  • Miniature Space Constraints: The gauge length is only 1.0 mm and the total base size is a tiny 4.0 x 2.0 mm. This allows you to measure stress concentration points at sharp corners, weld joints, micro-components, or inside small machinery.
  • Long-Distance & Outdoor Monitoring: The "VSE3" suffix means it comes pre-wired with a 3-meter vinyl-insulated cable. This eliminates the need for delicate micro-soldering on-site, making it perfect for field bridge monitoring, pipeline testing, and large civil engineering structures.
  • Automotive & Aerospace R&D: Used to test chassis deflection, wing structures, and suspension parts that use high-strength stainless steel alloys under dynamic load conditions.

• Piping Systems: Measuring thermal expansion stress in chemical plants or oil pipelines.
• Medical Equipment: Stress-testing stainless steel orthopedic implants or surgical tools.
• Infrastructure: Monitoring load distribution on stainless steel bolts, cables, or architectural components.

Strain gages are of the stucture, in which a metallic foil film in the thickness of a few microns is glued on a thin electrically insulated sheet (such as polyimide, polyester and so on). This foil film is cut down by photo- etching method in the shape of strain gages which can be made with the negative film masks of the strain gage patterns. These photo-etched strain gage patterns are trimmed to have a standard resistance value satisfying requirements as the strain gages DISTRIBUTED BY: Semiki instrumentation Co., Ltd Email:  sales@semiki.com Office tel: +84 28 2253 3522 ~DOING OUR BEST FOR YOU~
