This edition of our company ma-gazine The PRofileђ is published in eight languages which serve to demonstrate the fact that PR elec- tronics is now achieving local market presence in all of Western Europe and on the way to gaining a similar presence in the USA and Canada.The most recent expansion of our distribu-tion and support network is the foundation of subsidiaries in Barcelona and Boston improving our ability to dispatch orders from day to day in Spain and the USA. Aided by efficient, stock- holding distributors, we now have global coverage with rapid delivery backed up with technical...

Mounting in Standard DIN Form B Sensor Head For FOUNDATION Fieldbus systems PRetop 5350 is the only transmitter on the market for mounting in a standard DIN form B sensor head, i.e. it does not require a special mounting head which is 2 to 3times larger and more expensive. Alternatively, if the transmitter is not to be mounted in the sensor head, it can be mounted on a DIN rail. Increased Safety The module features two analogue function blocks and thus provides easy access to difference, average, and redundancy measurements. PRetop 5350 is there- fore very well suited in applications...

Efficient Quality Control > 6 Mounting of components on the backplane is carried out on our automated SMT production line. Each backplane is checked and passed against specified quality criteria and followed by travelling quality con- trol documentation (ISO 9001). The use of surface mount technology reduces the need for cabling and practi- cally eliminates the risk of mounting errors. > example of the flexibility of the overall solution. The Flexibility of PRewire 7101 Backplane Applies to: The number of channels - from 2 to 16 signal con-ditioning modules on one backplane. Configuration...

Process Engineer Michel Naveau of Rhodia says about the solution: Interesting Price We made our choice on the basis of PRӒs ability to manufacture back-planes matching our specifica-tions within a very short time frame. Modules of the type PRetrans 5115 (signal cal-culator) with analogue inputs allow us to du- plicate the 420 mA measurement signal and thus send two signals to the SCADA system and the fail- safe controller simultaneously Ŗ independently of and isolated from each other. Furthermore, these modules allow us to choose to which output an alarm is sent in case of cable breakage or...

UL 3121-1 (EN 61010): This is a new product-specific, general Standard for Safety for Process Control EquipmentӔ. This standard specifies general safety re-quirements for electrical equipment intended for professional, industrial process, and educatio-nal use, including equipment and computing devices for measurement and test, control, and laboratory use, and including accessories intended for use with the above (e.g. sample handling equipment). The standard covers such products as power supplies, transmitters, and transducers. UL 1604 (EN 50014/50021): The standard for Division 2 in...

ment and assessment of the tank content by means of a magneto-resistive level sensor 2 metres long. Display of Content Volume The non-linear correlation between the level and the content volume can be depicted in a sounding table with the desired degree of accuracy (number of mea- surement points). The PReview 5511 display features a linearisation function allowing the sounding table to be entered so that both the reading and the analogue output of the display follow the content volume of the tank. The analogue output is used to send informa-tion to the cooling system about the quantity of...
