MEASUREMENT + INSTRUMENTATION : PRODUCTS + SERVICES

Digital measurement, data management and SCADA

Process measurement, secure access to measurement data, and secure storage of measurement data as well as the visualisation and analysis of the data, pose ever- increasing challenges. Among other things, these are also driven by increasingly strict IT guidelines, growing complexity of infrastructures and data protection – all in the context of rapidly evolving digital market dynamics. Simplifying the world of measurement data Camille Bauer Metrawatt has introduced the innovative SmartCollect ® SC² HMI/SCADA software to manage data in a user-friendly way. SmartCollect ® SC² is based on a new state-of-the-art platform with a visually appealing 2D/3D web-based graphical user interface. It has been developed to deliver simplicity, functionality, flexibility and a convincing price: performance ratio. The system architecture Essentially, it is a web-based HMI that does not require a complicated client-server architecture. The advantage is obvious. The security of the IT infrastructure stays in the hands of the user and is not affected by how the user soft- ware accesses the HMI. The user runs the application via WebGUI and the application is monitored using role-based access control (RBAC) and an AuditLog. According to the customer-specific configuration, measurement data is se- curely stored on a server, locally or in the cloud, and re- trieved for visualisation by the web-based HMI at the front end. In addition, many common communication protocols are available for system integration. Simplicity and high performance together Innovative functionalities are at the core of SmartCollect ® SC². For example, infrastructural overviews of measure-

ment data can be displayed in 2D or 3D graphics as well as in single-line diagrams. A dashboard enables the user to evaluate progressions in the relevant measurement data, to analyse them with synchronised zoom functions and to determine trends from them. In addition to visual- ising events and alarms, there are export functions for the measurement data. A key feature of the software is ac- cess to individual measuring points, from the HMI of the SmartCollect ® SC² directly into the respective WebGUI of the measuring devices. Here, settings and further meas- urement data can be viewed and deeper analyses can be done. Individual processes can also be represented graphically. Access in the Camille Bauer products is protected against unintentional manipulation with further integrated protective functions such as RBAC, Client Whitelist, AuditLog, Syslog, Secure Firmware, 16GB SD card and Hypertext Transfer Protocol Secure (https). The customer can set up all the options described above flexibly. The user can implement user profiles in order to adapt them later to the corresponding users. A wide range of national languages is supported. The SmartCollect ® SC² also offers a user-friendly option to process a variety of data, including data from measuring devices and sensors from different The NGR operates on a modular sensor concept, adaptable for every application and suitable for almost every liquid. The measuring principle functions inde- pendently of the medium’s density, temperature, pres- sure, humidity and conductivity. Key features of the Kobold NGR include: - Measurement of liquids - Temperature range: -20°C…+100°C - Pressure range: -1…+10 bar - Output: 4-20 mA/0 – 10 bar switching output PNP or NPN - Probe length: max. 2 000 mm for monoprobe and coaxial tube, max. 4 000 mm for wire rope. up presents four buttons and a display to provide for quick and easy adaptation to each application.

liquids, grinding and hydraulic oils as well as mixtures with cleaning, degreasing and care products. The NGR can also work in deposit- forming and foaming liquids. The NGR’s guided radar uses time-of-flight technology to measure electromagnetic puls- es. The time difference between the sent pulse and the reflected pulse is used to calculate the level, both as a continuous value (analogue output) and a free position switching point (switching output). The flexible probe can be changed or cut, allowing for the sensor to be integrated quickly into any application. The sensor’s intuitive set-
