Benefits
- no reclamation due to wall thickness
- no faulty rejects
- hardly any maintenance costs
Contactless
Measuring Principle
The device works
contactless. A light line is projected onto the glass surface. The
reflections at front and rear side of the glass are displayed on CCD
line sensors and their distances are evaluated.
Structure and Installation
The device consists of a measuring gauge head, measuring electronics as well as instruments for positioning of the gauge head.
Installation can be done by using an available testing station with a rotation station, for example CO or TIM machines.
The measuring
electronics generates an output signal if the wall thickness is below
the minimum tolerance, which is transferred to the control of the
available selection machine.
Adjustment
The adjustment after job
changing isn't complicated at all and is carried out within a few
minutes. Measuring height, distance and inclination of the sensor to the
container surface are to be adjusted.
The adjustment procedure is
supported by a number of displays and service functions from the
electronics.
Advantages
- Measurement is possible for round and many non-round containers.
- The device measures a spot and does not supply the average wall thickness from a relatively large area like the known contacting devices. Narrow, restricted, thin areas (bull eyes) will be rejected.
- In many cases, measurement in the area of engravings is possible.
- Available rotation stations can be used, a special thickness inspection machine is not necessary.
- No limitation of the testing speed.
- No wear as usual at known contacting devices
- Stable measurement,
no drift. No further calibration.
Damages of the container are out of the question.
