* The MTY-7000 equipped with specially designed linear gauge measuring heads measures the pet bottle & preform bottle of PCO
Feature
- Measuring time is as short as 4 seconds in any one direction
- The MTY-7000 offers an accuracy of 4μｍ or less in terms of σ when repeated measuring the master gauge 10 times at a fixed point
- The measured values are digital displayed.
- GO / NG judgement result is indicated by the lamps. （Tolerances can be set as desired）
GO：The green lamp lights
+NG: The red lamp lights
-NG: The amber lamp lights - The measurement data can be output via the RS-232C interface.
- The MTY-7000 is a semi-automatic measuring system that allows easy operation and simplified measurement.
- With a small CCD camerea, thecondition of workpiece (pet bottle preform) setting can be checked.(12-inch monitor is supplied together)
- The MTY-7000 is designed with operational safety in mind.
- The workpiece (pet bottle & prefoem) can be measured from two directions (from the angles at 0°and 90°). (Automatic 90°-workpiece-rotation function is optional)
