Back-Pressure VS. Differential Air Gaging Back Pressure (Dual Master) Gages

  • Adjustable magnification; tooling flexibility.
  • Less costly tooling.
  • Higher air pressure: cleans part surface more effectively.
  • Two masters provide greater traceability.
  • More manufacturers; wide compatibility.

Differential (Single Master) Gages

  • Higher magnification, discrimination; longer range.
  • Greater tool-to-part clearance reduces wear, speeds usage..
  • Better stability, dependability; no drift. Better for automatic control applications, and data collection for SPC.
  • TSingle master makes gage easier, quicker to set.
