Proven Quality Control Solutions for Known Problems

Growing quality requirements demand a 100% quality control in the production. SMAC’s unique automated contact measurement solution was developed to solve the problems with existing inspection systems with LVDT, Camera, Laser, and manual gauging. It successfully automates inspection procedures and performs in the shop floor environment where conventional solutions have failed.


“GAUGE CORRELATION” - SMAC measurements can easily be correlated to manual gauge methods 

SMAC measurement system can be programmed with variable force/displacement that duplicates human hands and fingers with data feedback. Quick measurement of force or diameters/depths and locations to submicron accuracy for Quality Assurance. It is a great tool for industries where metrology is key.

SMAC inline quality control solutions are used for automotive parts and industrial components; thread check and quality measurements for casting parts, airbag components, automotive switches, touch screen, latch assemblies, and many more.

  • 100% inspection
  • Increased quality
  • SPC data acquisition
  • Process control feedback
  • Increased throughput


Why Use SMAC QC Solutions? quality_control

Comparison with conventional solutions:


  • Optical distortions
  • Require consistent lighting = No shadow
  • Vibrations = Blurred the image
  • Dirty environment (oil/coolant mist)


  • Reflective inaccuracies.
  • Problems with textured and or certain color surfaces.


  • Pneumatic, variables in air pressure cause inaccuracies
  • Non-programmable
  • Not linear: positional data and spring is non linear—must be scaled
  • Very short operating strokes.
  • Poor positional resolution
  • Require the motion provided by another source
  • Poor force control (by Pneumatics)

Eddy Current

  • Surface of the material must be accessible.
  • The finish of the material may cause bad readings.
  • Based on its level of conductivity
  • The depth of penetration into the material is limited (Especially thick cast parts and blind holes.)
  • Expensive & fragile (Ceramic core) probe tips ($300 to $500+ to replace)
