In order to comply with the highly complex requirements of the new 2006/42/EG machinery guidelines, Sensor-Technik Wiedemann GmbH (STW) has developed the new F02 pressure transmitter. It complies with the highly complex requirements of the new 2006/42/EG machinery guidelines. The F02 possesses the necessary properties required by the EN ISO 13849-1 and IEC 61508 standards for the compliance of functional safety. As a result, it is ideal for use in systems that require a pressure transmitter with a PLd Performance Level or a Safety Integrity Level of SIL2. Consistent with STW's many years of experience in the mobile hydraulic applications sector, particular attention was paid to typical prevalent conditions such as vibrations, EMC requirements, thermal stress loads and protection against other external influences.
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.
