Determine inner diameter dimensions at a low cost!

This sensor allows for cost reductions in inner diameter measurements that would typically require expensive "air micrometers," and significantly shortens inspection times compared to manual "pin gauge" methods!

By setting the signal points at two locations, we can classify the inner diameter of the workpiece after drilling into three categories: NG (Not Good) / OK / +NG (Positive Not Good). The pass/fail signal is then output to the NC machine.

◆ Improvement Examples with the Two-Point Setting Air Micro Sensor

① Replacing Pin Gauges to Significantly Reduce Inspection Time
Manual workpiece "inner diameter inspections" using pin gauges can be time-consuming due to the insertion and removal process, and there may be variations in inspection results due to different operators. Automating the process with the "Two-Point Setting Air Micro Sensor" significantly shortens inspection times and improves accuracy.

② Replacing Air Micrometers to Achieve Significant Cost Savings
Inner diameter measurements using air micrometers with digital displays can cost between 300,000 to 400,000 yen per unit. By switching to the "Air Micro Sensor," the need for digital display functionality is eliminated, achieving a cost reduction of one-third.

◆ Product Lineup Based on Application
