350Ω gauges are generally preferred for modern designs as they consume less power and are less susceptible to heating effects, though 120Ω remains common in legacy instrumentation.
Strain Gauges Component Intelligence
Precision sensing for mechanical stress and structural integrity analysis.
What are Strain Gauges components?
Strain gauges convert mechanical deformation into measurable electrical resistance changes. Selection depends on the material under test, required gauge factor, thermal expansion coefficients, and the bridge circuit configuration used for signal conditioning.
How to Choose Strain Gauges Components
Selecting the right gauge requires balancing mechanical constraints with electrical signal requirements.
Gauge Factor
Higher gauge factors improve sensitivity but may limit the maximum strain range.
Resistance Matching
Standard 120Ω, 350Ω, and 1000Ω values must match your Wheatstone bridge input impedance.
Thermal Compensation
Ensure the gauge's thermal expansion coefficient matches the substrate to prevent false strain readings.
Bonding Method
Choose between weldable, bondable, or adhesive-backed gauges based on the installation environment.
Bridge Configuration
Determine if you need quarter, half, or full-bridge setups to cancel out unwanted bending or thermal effects.
