June 2014: Novel EMC tesiting Site

SCHIRMUNGSTECHNIK  develops textile Mode Stirred Chamber

A new type of Mode Stirred Chamber was set in operation at BTU Cottbus, (Technical University of Brandenburg / Germany). The new chamber, sized approx. 14m x 5m x 6m, was established by means of highly conductive textiles.
The flexible Walls of the chamber are excited mechanically, so an additional stirrer is not necessary.
In first tests, a fieldstrength of 100 V/m was generated with low amplifier power.
The Chamber has a 3m x 3m large shielded roller shutter, so it can be accessed by large vehicules. Additionally, it can be entered through a shielded steel door. The floor consists of copper plates.

The walls, made of highly conductive metallized rip-stop woven, are suspended from a free-standing support structure elastically. The host building's space was utilized in an optimal way.

News: Construction of Shielded Rooms

W+R Schirmungstechnik GmbH Completes 30 Shielded Rooms at Ruhr-Universität Bochum.

Shielded Room at the Ruhr-Universität, Bochum (Ruhr-University Bochum, Germany).

In the new building ID, 32 shielded rooms with a total ground area of approx. 1500 m² were equipped with a RF-Shielding by SCHIRMUNGSTECHNIK. This technique allows to perform hihgly sensitive measurements without interference from outside of these rooms. In addition, in some of the shielded rooms experiments were carried out, accompanied with high electric or magnetic fields intensities - without any danger for persons or machinery in the enviroment. SCHIRMUNGSTECHNIK delivered and installed the complete shielding system with a lot of customized detail solutions.
