Measuring Principle:

The Tool Kit is equipped with different inductive distance sensors. These sensors use the physical
effect of the change of a resonance circuit, which is caused by eddy current losses in conductive
materials. The losses depend on the distance between the coil in the sensor head and the
conductive surface. The circuit measures the losses and converts them into a linearized 0...10V
output signal.
The signals of maximal six sensors can be measured by the IDM2 Controller, which converts them
into numeric values and sends them via Bluetooth to a PC.
The software TomTom-Tools Measurement Studio (for Windows), which comes together with the
measurement tool is made to receive, store and process the values from the IDM Controller.
There are already 4 types of applications available in the software:
•
Raw Data Acquisition:
In this mode the data are one to one displayed in real time on the computer screen.
•
Roller Shaft Bending Measurement
This application is used on rotary kilns with 3 or more stations. It calculates automatically
the variation of shaft deflections, which are caused by a crank in the kiln shell.
•
Gear Run Out Measurement
The application is calculating automatically the radial and axial run out (eccentricity and
roundness) of rotating parts. (typically girth gears and mill trunnions)
•
Tire Run Out Measurement
The application is calculating automatically the axial run out (wobble) of a kiln tire
