MultiTC

MultiTC is the standard interface for connecting WYLER inclination sensors (ZEROTRONIC or ZEROMATIC) to a laptop.

The MultiTC not only ensures that the correct power is supplied to the sensors (5V to the ZEROTRONIC sensors, respectively 24V to ZEROTMATIC sensors), but ensures optimal communication between the laptop and the sensors as well. 

The MultiTC has the following features: 

  • The MultiTC provides an easy way to power the sensors, either through the USB port of a laptop and the wylerCONNECT, or via a separate 24V power supply.
  • Forwarding the measuring values of the sensors via the wylerCONNECT to one of the WYLER evaluation software such as the wylerDYNAM.
  • MultiTCs can be cascaded, i.e. several MultiTCs can be connected to each other, allowing a wide-area system configuration with several sensors.
  • With baud rates up to 57,600 bps, the MultiTC allows fast data acquisition.
  • Four LEDs allow simple monitoring of the status of the communication as well as of the power supply.

Configuration with two ZEROTRONIC sensors, connected to a RS232 port of a laptop, via a MultiTC.  Power is supplied from an external Power supply 24V.

Configuration with eight ZEROTRONIC sensors, connected to an RS232- or an USB port of a laptop, via  four MultiTC. Power is supplied from one or several 24V power supplies.

SHIP BUILDING / DETERMINATION OF DEVIATIONS IN PARALLELISM

Subject:

Precise inclination measurement on unstable bases as they exist on a moored vessel on the water are a huge challenge. 

 

Measuring task:

On a large ship moored in a harbor, the deviations from parallelism for several platforms must be determined. Based on this, the platforms shall be aligned afterwards. This should be done as efficiently and precisely as possible

CIVIL ENGINEERING / MONITORING OF BRIDGES

Subject:

The deformation of a highway bridge must be continuously monitored, not only during construction but also afterwards, when the bridge is put into service.

 

Measuring task:

In order to get significant values regarding the deformation of the bridge, several points on the bridge must be monitored simultaneously. 

AIRCRAFT INDUSTRY / ALIGNMENT OF COMPONENTS IN AN AIRCRAFT

Subject:

During assembly, maintenance and repair of a large transport aircraft various components of the equipment must be precisely aligned to a reference platform. 

 

Measuring Task:

Two radar platforms must be aligned precisely parallel to the reference platform. The measurements must be carried out while other teams are working on the same aircraft.

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. 

MONITORING OF A HISTORICAL BUILDING IN KOREA

Subject:

An old and historically significant wooden building in the center of Seoul shall be preserved despite aggressive environmental influences, like the exhaust gases from cars.

 

Measuring task:

The building shall be continuously monitored with inclination sensors.

MONITORING OF A HIGH RACK WAREHOUSE

Subject:

Automatic high rack warehouses can reach very large dimensions:

80 m length, 45 m width and 30 m height are no exceptions. Despite these dimensions and despite the high speed of the transportation system, each bin must be placed very accurately at its predefined location. In order to reach such accuracy, the alignment of the racks is of key importance. The exact verticality of each rack has therefore to be ensured. Already smallest deviations will change the distance to the transportation system and could cause errors. The bins could get blocked and get damaged or even fall.

 

Measuring task / Goal:

The verticality of each rack in the high rack warehouse must be monitored permanently.

 

HEELING MEASUREMENT ON A SHIP

Subject:

Part of the homologation and certification of a ship is the measuring of the heeling: The buoyancy is measured as a function of the load and specifically of the maximal load. By pumping water into the ballast tanks, or by loading containers, the heeling of the ship is changed. Thereby certain limits of heeling may not be exceeded.

 

Measuring task:

On a ship which is at moored in a harbor, the inclination, or heeling, should be measured during a loading test.

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.

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. 

ADJUSTMENT OF A CEMENT OVEN DRIVE

Subject:

Cement is manufactured in a so-called turn-tube oven. The oven itself is a about 50 to 70 m long, slightly tilted steel tube with a diameter of 4 to 5 m which turns around its longitudinal axis (max. 20 rpm).

 

Measuring task:

The inclination of the cement-oven drive- gear wheel (diameter approx. 1.5 m) should be 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.

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.

PITCH AND ROLL MEASUREMENT WITH 2D-ZEROTRONIC MEASURING UNIT AND MT-SOFT-SOFTWARE

Subject:

Alignment of a turning lathe with an oblique bed and establishing a pitch and roll measuring protocol for the longitudinal and transversal axis.

 

Measuring task:

The machine should first be very accurately levelled in both X- and Y-direction.

Afterwards a pitch and roll measuring report with numerical and graphical information is required.

CIVIL ENGINEERING / MONITORING OF VERTICAL MOVEMENTS IN NATURAL GROUND

Subject / Measuring task

When excavating tunnels passing under e.g. existing railway installations, or roads where several owners are involved, the question of liability is raised regarding potential damage done to these structures. 

The owners then often ask for a permanent monitoring of the site to get early warnings as well as proof. 

DAM MONITORING

Subject:

The requirements regarding long term monitoring of dams are continuously increasing. Where it was enough earlier to carry out periodic measurements, today more and more permanent monitoring is required.

 

Measuring task:

The changes in inclination in both directions (mountain <-> mountain and water <-> air) of a dam shall be monitored continuously.
