CALIBRATION OF TESTING MACHINES

Measuring task:

Many testing machines, like those used for impact testing, require precise angle setting. They therefore must be recalibrated regularly. 

MEASUREMENT OF THE FLATNESS IN AN OVEN WITH LIMITED HEIGHT

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.

CONTINUOUS MONITORING OF AN OBJECT, WHICH IS EXPOSED TO STRONG TEMPERATURE CHANGES

Subject:

On a radar installation which is exposed to significant temperature changes as well as to direct sunlight, precise, reliable and continuous inclination measurements should be carried out. 

All high-precision instruments are sensitive to temperature changes. Significant temperature changes inhibit precision measurements and can even prevent them.

 

Measuring task:

Precise and continuous monitoring of the inclination of the base of the radar station. 

INCLINATION MEASURING OF A SATELLITE DURING A SYSTEM TEST IN A TEMPERATURE VACUUM CHAMBER

Subject:

Testing of a satellite in a temperature and vacuum chamber under conditions like in space: temperatures from –30°C to +60°C and vacuum. 

 

Measuring task:

Level all systems of a satellite to each other. A precise surface on the satellite serves as horizontal reference point. The inclination of this horizontal reference must be within ±0.001 mm/m. 

CONTROLLED CRADLE TO LIFT AND PLACE PAYLOAD FAIRING OF A ROCKET

Subject:

The payload fairing covers the goods transported and provides aerodynamic to the leading end of the rocket. As the payload fairing is a highly complex unit, no scratches or even dents are acceptable. To lift and to position the payload fairing a cradle is used. 

 

Measuring task:

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 are defined regarding misalignment. Overshooting these limits must activate an alarm and disrupt the lifting actions. 

ZEROTRONIC SENSORS IN STRONG MAGNETIC FIELDS

Subject:

A customer would like to measure his machine despite the presence of strong magnetic fields.

 

Measuring task:

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 and of instruments which are not sensitive to heavy magnetic fields. 

MONITORING OF SYNCHROTRONS

Subject:

Synchrotrons require a very accurate long-term monitoring of the alignment and the inclination of the girders carrying the electromagnets.

 

Measuring task: 

All girders must be monitored continuously. To achieve a high precision with this measuring task, an excellent long-term stability of the sensors is decisive.

RESEARCH - DEVELOPMENT / MEASUREMENT OF A ROAD SURFACE

Measuring task / Goal:

Based on the above mentioned information a standard road surface shall be recorded in a form which enables the integration in a software. This software will control and monitor a testing station in a way that that car test can be performed under laboratory conditions fully integrating the road surface profile. In order to establish this standard road profile, several dozen kilometres long, in an efficient way, the profile shall be monitored and recorded in the longitudinal direction by the aid of inclinometers during driving.
