DAQ measurement data acquisition: <\/strong>
with hardware and software<\/strong><\/h2>\n\n\n\n

In measurement data acquisition, physical variables such as temperature, pressure, current or voltage are recorded by sensors and converted into computer-readable values in measuring devices. This measurement data can then be processed, analyzed and visualized, providing the basis for data-driven business decisions or processes. With the systems from Delphin Technology, measurement data acquisition can be adapted precisely to the specific needs of your company. Thanks to a modular design and perfectly interlocking hardware and software solutions, we support companies worldwide in the digitalization of production lines, test benches or in the laboratory. Test benches<\/a> or in the Laboratory<\/a>.<\/p>\n\n<\/div>\n\n

Hardware for measurement data acquisition<\/strong><\/h2>\n\n\n\n

In order to turn physical parameters into usable data, the parameters must first be recorded where they are generated. Various sensors are used for this purpose, for example to record temperatures in the working area of a machine, pressures in containers or emitted sound and convert them into electrical signals. These analog signals are then sent to measurement data acquisition systems where they are transformed into digital values. Measuring amplifiers, also known as DAQ or DAS systems, are used for this purpose. Put simply, DAQ systems linearize, isolate and amplify the output signals from the sensors, thereby preparing them for digitization. Once the transformation from analog to digital signals has been carried out in the DAQ system, the data is sent to central software for further processing via various interfaces (LAN, WiFi, 5G, etc.).<\/p>\n\n<\/div>\n\n

Software for measurement data acquisition<\/strong><\/h2>\n\n\n\n

The through Data logger<\/a> or measuring devices must be merged, processed, stored and archived - because this is the only way to obtain a usable, useful overview from the many individual pieces of information. With the Delphin Data Center<\/a> is a DAQ software solution that can be used to collect and process data from a wide variety of sources, both in the cloud and on-premise on local servers. However, the data collected in a DAQ environment is not initially interpretable by humans. Rather, it is a series of strings of numbers in huge databases. Visualizing these numbers and making them available in dashboards for evaluation and analysis is the task of specialized software such as ProfiSignal 20<\/a> from Delphin. Depending on requirements, these software systems enable the implementation of condition monitoring tasks in production or predictive maintenance.<\/p>\n\n<\/div>\n\n

Measurement data acquisition system - the perfect solution<\/strong><\/h2>\n\n\n\n

The perfect acquisition of measurement data depends on the optimum interaction of all components used. With Delphin Technology solutions, you can count on maximum quality and reliable measurement results in every detail. For example, galvanic isolation to protect the sensor signals from being influenced by external electrical potentials is part of the standard equipment of our data loggers. With isolated inputs, we ensure the integrity of the signal chain and guarantee that the output signals of all connected sensors correspond exactly to what is measured on site. A special feature of our systems is maximum flexibility in use - thanks to high-precision, universal analog inputs, innovative expansion and networking concepts or use as an edge device at the edges of the network. In combination with DAQ software, any requirements for modern measurement data acquisition systems can be realized. Whether Decentralized data acquisition<\/a> and monitoring, continuous monitoring of distributed machines or systems, low-power applications in environmental measurement technology or building monitoring: We are your powerful partner when it comes to precise, user-friendly and future-proof acquisition of measurement data.<\/p>\n\n<\/div>\n\n

What measurement data can be recorded and how exactly does it work?<\/strong><\/h2>\n\n\n\n

In principle, all physical parameters can be recorded by sensors and converted into measurement data. The basis is always a sensor that is optimized for the respective application. For example, thermocouples or resistance thermometers are used to measure temperatures, while acceleration sensors detect shocks or vibrations. Current sensors can be used to measure direct and alternating current, while humidity sensors measure the humidity in rooms or in the working areas of machines. Speed sensors, torque sensors, pressure sensors and flow sensors are also used millions of times in a wide range of industries. Regardless of the measurement task, the process of recording and processing measurement data is always the same:<\/p>\n\n\n\n
