More Information

Overview Manuals Pneumatic Setup Fixture Alignment Gauge Validation Product Applications

Features:

  • Pneumatic probe actuation: Regulated air extends the contact head independently of the machine slide.
  • Controlled measurement contact: Pressure, alignment and target presentation determine how the probe seats on the part.
  • Environmental installation: The air connection contributes to the documented ingress-protection condition.
GT-A10 forms the contact-sensing portion of a GT measurement channel for automated gauging.

The pneumatic circuit must deliver stable, clean pressure and allow the probe to extend and return without binding.

A qualified fixture demonstrates repeatability across the real part range while preventing excessive contact force or surface damage.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Pressure control: Use clean regulated air and keep the setpoint inside the manufacturer’s operating range.
  • Tube connection: Secure the approved tube and keep the outlet path free from contamination.
  • Response check: Observe extension and return through repeated cycles before measuring parts.
  • Failure state: Decide how the machine reacts if air pressure or probe return is lost.
  • Normal contact: Align the probe with the measured surface to avoid side loading.
  • Travel margin: Set the mounting position so all valid parts remain inside the working stroke.
  • Rigid support: Prevent fixture deflection from becoming part of the measured displacement.
  • Surface protection: Confirm the contact does not damage or deform the target.
  • Reference check: Establish the measurement baseline with an approved master.
  • Cycle repeatability: Test repeated pneumatic actuation on representative parts.
  • Temperature behavior: Recheck after the machine reaches normal thermal conditions.
  • Reject proof: Challenge both accepted and rejected samples before enabling automatic disposition.
  • Automated height gauging: Extends a probe to compare part position or height.
  • Seating confirmation: Detects whether a component reaches the qualified assembly position.
  • Thickness checks: Measures contact displacement when the fixture controls part presentation.
  • In-process inspection: Adds pneumatic probe actuation to a production measurement station.
Description
GT-A10 uses regulated air pressure to extend its contact probe toward the workpiece, separating probe actuation from the machine mechanism.

The air outlet arrangement on GT-A10 forms part of the environmental sealing condition, so tubing and pressure settings must follow the documented installation.

Commissioning GT-A10 requires proof that probe force, alignment and return behavior suit the target without marking the surface or trapping the mechanism.

Technical notes
GT-A10 depends on clean regulated air within the approved pressure range. Excess pressure, blocked exhaust or misalignment can increase contact force and measurement error. Isolate machine motion, verify tubing and regulator function, observe full probe travel, and qualify repeatability on representative parts before the measurement result controls acceptance or rejection.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
GT-A10 extends slowly after maintenance. Which parts of the installation should be checked?
Inspect regulated pressure, tube routing, contamination, exhaust path and probe freedom before changing amplifier settings.
Can GT-A10 be operated at higher air pressure to improve speed?
No. Stay within the published range; excess pressure can change contact force, damage the mechanism or distort the measured part.
A GT-A10 measurement changes when the fixture is touched. What does that suggest?
Check fixture rigidity, mounting torque, probe alignment and cable or tube forces that may be moving the measurement reference.
Does GT-A10 retain its enclosure rating if the air connection is left open?
No. Follow the specified air-tube condition and prevent foreign material from entering through the joint.
GT-A10 repeats on a master but not on production parts. What should validation add?
Include real surface finish, curvature, temperature, presentation and pneumatic cycle timing rather than relying on one ideal master.
A GT-A10 probe does not return fully. Should automatic inspection continue?
Stop the station, isolate motion and air, then inspect pressure, tubing, contamination and mechanical binding before trusting any result.
