(STW) SENSOR-TECHNIK WIEDEMANN GMBH

The Pressure Switch F01 fulfils the high requirements of the EN13849-1 Machinery Directive. The F01 can be used for systems with Performance Level PL d and for safety-critical applications. The F01 has an E1 approval. The F01 is available for pressure ranges from 10 to 1200 bar and has two switching outputs which switch inverted to each other. The F01 is also available with one switching and one analog output. The current output is read back by the F01 to ensure the output signal is emitted correctly. To be able to use the F01 in many applications, users can select different pressure connections. The electrical contact takes place via a 5-pole M12 connector. Through the calibration of the transmitter via temperature, a total accuracy of 1 % FS can be achieved within a range of 0...80 °C. The maximum media temperature totals +125 °C. The stainless steel parts coming into contact with media guarantee maximum media compatibility in combination with the welded thin-film measurement cell.

The ESX-4CS-GW is the first control unit of the fourth generation. The new platform is in turn based on the current AURIX family by Infineon. This AURIX family contains multicore and single core processors. The ESX-4CS-GW (C = Compact, S = Small, GW = Gateway) is equipped with a multicore processor with four internal processors. Three of these cores are available for the creation of your application. The fourth core serves as the lock step core for safety-oriented applications. Furthermore, the processor is equipped with the following internal memories: 8 MB Flash, 2 MB RAM and 32 kB EEPROM. An external 16 MB flash memory is also available. As the device was designed as a central gateway module, six CAN interfaces are available in addition to the five Ethernet interfaces, four of which represent an Ethernet switch for mobile applications. Furthermore, the device can support CAN-FD. The number of I/Os (12 x In, 6 x Out) has been adapted to the concept of a gateway module.

The M01 series has been especially designed for applications in adverse ambient conditions in the same way value is placed on high resistance to aggressive media. Furthermore, the modular principle permits many combinations of pressure connection, pressure range, output signal and connector, so that the right sensor can be found for most applications. For pressure ranges from 10 to 2000 bar, which are frequently required for use on mobile machines, welded stainless steel measurement cells are used which are suitable for media temperatures from −40 to +150 °C. Depending on the type of measurement cell and the material coming into contact with the media, the M01 is resistant to aggressive/non-aggressive gases and liquids. On request, versions in 316L design for use in hydrogen pressure measurements are available. In addition to CE and UL certificates, every M01 product with a 1.4542 stainless steel measurement cell possesses an E1 approval verifying its suitability for use in vehicles.

The pressure switch P01 has been designed especially for use in mobile machines. The EMC characteristics as well as the impact and vibration resistances have been designed for this field of application. This facilitates their use in adverse ambient conditions such as can be found in mobile hydraulics. The integrated electronic switches (NPN or PNP) can be preconfigured ex-works. The P01 is available for pressure ranges from 0...10 bar to 0...1200 bar, whereby a switching accuracy of 1 % of the measurement range end value can be achieved. The maximum permitted media temperature totals 150 ºC; the ambient temperature totals 125 ºC. The parts coming into contact with media have been produced from stainless steel (1.4548) and guarantee, in combination with the welded thin-film measurement cell, maximum media compatibility. Optionally, a damping device can be integrated into the media access.
