Bus technology Profibus® DP (Decentralized Peripherals) stands for easy, quick, cyclical and determined process data exchange between a bus master and the assigned slave instruments. This process is based on the well-tried RS485 transmission technology. In the background of every Profibus® PA system is a Profibus® DP network behind the segment coupler. Based on its quick and cost-effective transmission technology, Profibus® DP is the best choice for applications in areas which are not intrinsically safe (non Ex).

WIKA precision sensors The ® DP transmitter is based around a sensor design with integrated dynamic temperature compensation. It offers the user an accuracy up to 0.1 %, without any additional temperature error, within the temperature range of 0 ... +50 °C. Fully-welded and with in-house manufactured thin-film and piezo sensors, there is absolutely no need for additional sealing materials. WIKA's sensors are already known for their high load cycle stability, resistance against pressure spikes and low non-repeatability.

Safety Through coordinated EMC measures, in combination with the integrated galvanic isolation within the instrument, a high level of data security is guaranteed, even at transmission rates of up to 12 MBaud. Comprehensive diagnostics routines, as well as the determination of the medium temperature, are available via Profibus® DP services in accordance with EN 50170. The electrical connections are achieved using M12 x 1 circular connectors per IEC 60947-5-2 for the data transmission and power supply. Thus an ingress protection of up to IP 65 is achieved and a simple and secure connection to the bus is ensured.
