PRINTING INDUSTRY / ADJUSTMENT OF STANDS AND PRINTING CYLINDERS

Measuring task / Goal:
Each single colour unit provides horizontal and/or vertical reference faces which must be used during the manufacturing process in the production plant as well as for the adjustment of the printing line. The positions of the reference faces must be adjusted in accordance to each other, measured, and a record must be printed. The positions of the printing cylinders must be precisely aligned to each other (horizontally).

POWER SUPPLY SECTOR / ALIGNMENT OF LARGE PUMP SHAFTS

Measuring task / Goal:

  • The horizontal positions of the connecting lines between the bearing faces on the bearing ring for the stator must be checked. The flatness and the fully horizontal position of the bearing ring must be assured.
  • The pump housing, one floor below, disposing of a round reference face must also be adjusted fully horizontally

The centre points of the pump shaft and the drive shaft of the motor must be aligned to each other in order to assure that the transmission shaft flanged in between can work free of any bending moment.

MONITORING OF A HIGH RACK WAREHOUSE

Measuring task / Goal:
The verticality of each rack in the high rack warehouse has to be monitored permanently.

POSITIONING OF A HEAVY PART WITH AN OVERHEAD CRANE

Measuring task / Goal:
In order to achieve the required accuracy the bending of the building respectively of the overhead crane should be measured. With the resulting values the vertical correction of the crane should be calculated .

ADJUSTMENT OF A CEMENT OVEN DRIVE

Measuring task / Goal:
The inclination of the cement oven drive gear wheel (diameter approx. 1.5 m) has to be exactly the same as the inclination of the turn-tube oven gear wheel (diameter approx. 6 m). The required accuracy is 0.01°  0.2 mm/m.

CONTROLLED CRADLE TO LIFT AND PLACE PAYLOAD FAIRING OF A ROCKET

Measuring task / Goal:
The balancing and weight distribution cross at the head of the cradle should be monitored in both axes. Deviation from horizontal alignment must be visualized at the cranes control panel. Thresholds in each direction limit maximum allowed misalignment. Overshooting the limits must activate an alarm and disrupt the lifting action. The display unit should facilitate manual corrections of the centre of gravity alignment by joystick. Failures of the monitoring system must be signalled by alarm condition.

ZEROTRONIC SENSORS IN STRONG MAGNETIC FIELDS

Measuring task / Goal:
The user of a particle accelerator would like to accurately measure and adjust the parts of his accelerator. The strong magnetic fields allow only the use of non-magnetic material. Only instruments that are not sensitive to heavy magnetic fields can be used.

MONITORING OF SYNCHROTRONS

Measuring task / Goal:
All girders have to be monitored continously. In order to achieve a high precision with this measuring task, an excellent long term stability of the sensors is decisive.
