BlueTC

The BlueTC with or without radio transmission was developed as an alternative interface to the  BlueMETER SIGMA and BlueMETER BASIC for using the BlueLEVEL and BlueLEVEL BASIC inclination measuring instruments.


It is possible to send measured data via an RS232/485 port to a printer, a PC/laptop or the WYLER software wylerSPEC, wylerDYNAM or to other software such as LabEXCEL.


Advantage compared to the BlueMETER SIGMA/BlueMETER BASIC connected to BlueLEVEL/BlueLEVEL BASIC instruments are:

  • Simple configuration; BlueTC is only an interface between instruments and PC / laptop
  • Cost effectiveness (in case of wireless data transmission)


Disadvantage compared to the BlueMETER SIGMA/BlueMETER BASIC connected to BlueLEVEL or BlueLEVEL BASIC instruments are:

  • No display of the measured values of the connected instruments [A] and [B]
  • Menu less extensive and less comfortable due to missing display

MACHINE TOOLS / CHECKING OF ROTATION ERRORS

Subject:

Machine tools must be checked periodically for geometrical deviations, since changes of the geometry have a direct influence on the quality of the parts manufactured on that machine. 

It is very important that during the displacement in one axis the tool will follow a straight path compared to the table. On machines of light-weight construction the table can show a deformation due to its own weight. 

If the complete machine construction is tilting during the displacement of the table this is a sign for insufficient stability of the foundation or for a flexibility of the stand (damping elements).

 

Measuring task:

The geometry of a machine tool must be verified. The check must show rotational errors of the table during displacement. The measurement should be made reliably and efficiently. 

 

PRINTING INDUSTRY / ADJUSTMENT OF STANDS AND PRINTING CYLINDERS

Subject:

A modern multi-color printing system consists of several separate units, one unit per primary color. To achieve high-quality print products, these units must be precisely aligned and adjusted when assembled.

 

Measuring task:

Each single color 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).

Measuring task:

  • 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 horizontal position of the bearing ring must be assured.
  • The pump housing, one floor below, must be adjusted horizontally as well.
  • The center 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 can work free of any bending moment.

Subject:

A bio-technical company must measure the flatness of plates in an oven (at room temperature), to ensure that all objects stored in that oven are horizontally aligned. Distance between plates are only 100 mm. Size of each plate is 800 mm x 800 mm.

Normally a BlueSYSTEM Sigma together with wylerSPEC is used for flatness measurement. For this application here the height of the instruments exceeds the space available.

 

Measuring task:

Flatness measurement of the plates in the oven with precision inclination measurement instruments, despite the limited space available.

ALIGNMENT OF AN INJECTION MOLDING MACHINE WITH WIRELESS INCLINATION SENSORS

Subject:

Each injection molding machine must be properly aligned during commissioning. This process uses 5 precision spirit levels and requires 2 technicians. One of them is reading the spirit levels and the other one is adjusting the 6 supports. This is an iterative and tedious work, since all 5 spirit levels must be re-checked after every adjustment. The available height on each of the 5 measuring points is limited to 120 mm.

 

Measuring task: 

The customer is searching for a more efficient solution for this process during in-house commissioning as well as for the commissioning

at the customers premises. If possible, the adjustment should be done by one single technician. To assure that no instrument is accidentally pulled down, a wireless solution is favored.

POSITIONING OF A HEAVY PART WITH AN OVERHEAD CRANE

Subject:

In a large production hall, a heavy part shall be positioned in the correct height with an overhead crane in order to allow a stress-free mounting. First tests show that the building is not stable enough: Depending on the weight of the part, vertical offsets are measured which are larger than the required positioning 

accuracy.

 

Measuring task: 

In order to achieve the required accuracy, the bending of thebuilding respectively of the overhead crane should be measured.From these values, the vertical correction of the crane should be calculated.

ADJUSTMENT OF A CEMENT OVEN DRIVE
