F02 pressure transmitter for safety related applications
Thanks to the use of an in-house thin-film pressure measurement cell, which is welded to the pressure adapter and high-quality materials, which are tried and tested in the automobile industry, the F02 is compatible with an extremely wide range of media and displays a high level of mechanical stability. Through the intelligent evaluation of the measurement cell signals it is possible to identify cell drift (e.g. from overload) during operation, so that PLd with a Cat. 2 architecture can be achieved. The high burst pressure of up to 10 times the nominal pressure provides the required safety in extreme situations.
The F02 will be available as a serial product in the 2nd quarter of 2014 with pressure ranges of 10 bar to 1,000 bar. The output signal is present on two outputs in parallel, though the second output presents an inverted signal. Users are able to choose between a ratiometric and 4-20 mA output using three wires. The maximum allowable media temperature range is -40...+150 °C. The overall error is better than 1% FS in the compensated range of 0...+80 °C. A multitude of available pressure adapters and the compact design guarantee the broadest level of flexibility for integrating the product into existing machines. Electric contact is ensured via a 5-pin M12 plug. This transmitter naturally possesses E1 accreditation for its areas of application. As a result of its output circuitry, the F02 fits in optimally with STW's safety controller family ESX®-3XM and ESX®-3XL as well as all common safety controllers on the market.

Warum Big-Data-Analysen oft scheitern
Rund zwei Drittel der 152 Namur-Mitgliedsunternehmen sind davon überzeugt, dass die Datenanalyse prinzipiell zur Optimierung von Anlagen geeignet ist. Die Umsetzung von Big-Data-Analysen verläuft jedoch in den Betrieben eher schleppend, wie eine Umfrage der Technischen Universität München ergab. Die Wissenschaftler erklären, warum das so ist und warum Big-Data-Analysen oft scheitern.Weiterlesen
