face that is transparent, measurable and rateable. Hence we disclosed last year the magnetic interference limitations of our sensors (see FRAUSCHER-NEWS 04/2009). However, we want to take it a step further.

We want to provide railway operators and rolling stock manufacturers with a measuring device that allows comprehensible standard rating of the electromagnetic interferences along the rail caused by the different vehicles types. To that effect we have developed a system in cooperation with ÖBB (Austrian Railways), which goes by the name of Magnetic Noise Receiver MNR. Accordingly, the newly developed HF and LF measuring antennas are rail-mounted simply by using rail claws much like our wheel sensors. The measurement data recorded

tions planned by our Company.

Presentations include wheel sensor RSR181, a further development of the RSR180 with plug-in cable, the FDS diagnostics

This also applies to us, as Frauscher Sensortechnik GmbH will introduce at InnoTrans 2010 a number of new products and further developments to any interested visitor of the trade fair and to our valued customers.

systems as well as a detailed update on the state of the art of wheelset detection on grooved rails.

InnoTrans is a very international trade fair. We are expecting many of our international customers and partners at our stand

The core of our new developments is our next generation axle counting system: The Advanced Counter. This system, which will not necessarily replace the current ACS2000, does, offer a large number of new options within its range of application, such as the integration with electronic signalling boxes. With a minimum of components and the possibility, for instance, to communicate safely with super ordinate applications using Ethernet interfaces, we have laid the foundation for a new promising generation of systems. By using our proven wheel sensor technology we have achieved a clear reduction in capital expenditure and life cycle cost compared with conventional systems.

and all relevant contacts from Frauscher‘s branch offices in the UK, China, Poland and Austria will be present. We are looking forward to exchanging opinions about the latest products, technological trends and correct system strategy. To this effect please take note of two important events: Our customer evening, Tuesday September 21, 2010, at 6 p.m., presenting Frauscher as a true Austrian company offering Austrian gastronomic specialities, and our lecture on Thursday September 23, 2010, between 3 and 4 p.m. in the Speaker‘s Corner about „Technological challenges for inductive wheel detection and axle counting technology of the future“.

As one of the world‘s leading manufacturers of highly available wheel sensors our Company has a special interest in the standardization of admissible electromagnetic interferences at the vehicle/general infrastructure interface. Work regarding CENELEC standard EN 50238-3 is now showing significant

Frauscher Branch Offices Optimal support for Frauscher customers and projects has always been a focal point of the Company‘s business philosophy. This objective has been achieved for many years now either through cooperation with partners in different countries or by establishment of branch offices for sales and services.

Frauscher Polska Sp. z o.o. – Poland The Polish branch office Frauscher Polska Sp. z o.o. with head office in Katowice was founded back in 1998. Over the years the company succeeded in establishing itself in the Polish market, wherefore, naturally, many projects now feature axle counting technology by Frauscher.

To mention but a few reference projects: E139 line E20 line CMK line Janusz Mikolajczyk Managing Director

Daniel Pytlik Head of Technical and Sales Department

Frauscher UK Ltd. – UK The already successful business development in the UK is also handled and expanded by a branch office. Frauscher UK Ltd. was founded in April 2010 in Yeovil, Somerset.

Among other projects Frauscher UK Ltd. supplies services to the London Underground.

on the reference diagram the evaluation can be immediately interpreted as measurement result (see figure 9).

However, knowing and displaying the residual spectrum is also of interest to infrastructure operators and vehicle manufacturers as rail vehicle licensing conditions also include interference spectra outside the preferred sensor frequencies. For this purpose the evaluation algorithm of the MNR recorder was expanded with a FFT analysis (see figure 10). This affords a continuous display of the entire emission spectrum.

Thus, the MNR probe with a MNR recorder is also suitable for lasting deployment at the rail (e. g. at check points) for the permanent monitoring of passing rolling stock.

The measuring device is monitored by means of a Helmholtz coil.

Frauscher-Short-Notes Business development in China CRCEF, a company of the CRSC Group has signed a cooperation agreement with Frauscher Sensortechnik GmbH regarding the integration of Frauscher wheel detection components into the new axle counting system of the JZ.GD series. The system is to allow deployment for all applications (subway, main line and high speed lines) and is based on the world-wide proven wheel sensor and evaluation technology by Frauscher. This cooperation agreement continues the long-standing partnership of the two companies and is an important element in the business development of Frauscher Group in China.

New board production line launched May 2010 saw the start of manufacture of the board production in its new premises (see figure 11). The new conditions increase production capabilities and optimise the flow of materials during the production process. Another advantage of the new production area is the expansion and improvement of the switching cabinet production (see figure 12). The pillar jib crane mounted in that area supports both production and packing/delivery of the axle counting systems mounted into the switching cabinets.
