Page 3: Overview
1.Overview This machine uses non-contact measurement to measure air pressure, in order to determine gaps between workpieces and air nozzles at a high level of precision. It compares the current value with a preset gap master value. If the current value is narrower than the master value, the gap is determined to be OK. -

Page 5: Response Time Characteristics
2. Specifications 2-3. Response time characteristics The response time is the time it takes for determination output to switch ON once a workpiece has been brought toward the air nozzle and has stopped moving (with air supplied to the machine). This will vary depending on factors such as the length and diameter of the piping from the OUT port to the air nozzle, the seating of the workpiece, and the supplied air pressure.The graphs below show response times when a workpiece is brought toward the air nozzle at a speed of 10 mm/sec. -
