How Does Air Gaging Work?

Air Gage Sensors measure the back pressure created when an air nozzle is brought in close proximity to the workpiece; the air gage readout measures this pressure and displays the dimensional change in the air gap.

Air Gaging Diagram

Air Gage Sensors are non-contact. Wear does not directly affect the accuracy of the gage and has a self cleaning effect on the workpiece ideal for shop floor environments.

Air Nozzles can be made with jet holes from .010″ to .100″ (.25 to 2.54 mm), with .050″ (1.25 mm) being preferred for most applications.

Connecting Rod – Bend and Twist Gage

Semi-automated, Fast and Accurate Connecting Rod Measurement

Western’s BT gage is a non-contact Bend and Twist Air Gage that measures engine connecting rod parallelism between Crank End bore (CE) and Pin End bore (PE) in the X and Y plane, and simultaneously measures the bore center-to-center distance. The modular test fixture is designed to accept many different size rods by simply changing the air gage spindles and lift plate.  The pneumatic powered lift plate makes loading and unloading fast and easy. A cycle time of just seconds means this gage is ideal for high volume production environments. Integrated air bearings ensure accuracy by keeping the rod centered on the spindle. The BT gage works with our AEK air-to-electric converter and our Gage-Chek readout.  See our online catalogue, page 33. To see it in action click here.

Features:

  • 5 second cycle time
  • Pneumatic lift loading and unloading
  • Interchangeable CE and PE air gages
  • Interchangeable Lift Plate
