DAQ measurement data acquisition:
with hardware and software
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 or in the Laboratory.
Hardware for measurement data acquisition
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.).
Software for measurement data acquisition
The through Data logger 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 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 from Delphin. Depending on requirements, these software systems enable the implementation of condition monitoring tasks in production or predictive maintenance.
Measurement data acquisition system - the perfect solution
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 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.
What measurement data can be recorded and how exactly does it work?
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:
- Physical parameters are recorded by a sensor and converted into electrical signals.
- The electrical signals are forwarded to DAQ hardware, such as a data logger, where they are converted into digital values.
- The data is forwarded to DAQ software via appropriate interfaces, where it is stored, processed and archived centrally.
- If required, the data records are processed, visualized, analysed and made available via dashboards for further use by humans.
What can a DAQ system be used for?
DAQ data acquisition systems can be used for a wide range of applications. In production, for example, the recorded data is used to optimize manufacturing processes and increase process reliability. The continuous condition monitoring of production machines, systems and devices is also based on precisely recorded measurement data. Another possible application is predictive maintenance - a maintenance and servicing approach in which sensor technology is used to detect faults and defects in components at an early stage. This prevents expensive, unproductive machine downtimes and significantly reduces maintenance costs. Even in the field of automation, nothing works without a reliable data basis - just like in the field of building monitoring or the monitoring of spatially distributed systems.
Machine data acquisition in practice: how measurement data acquisition works on a machine
Production machines are ideally suited for optimizing the running processes through measurement data acquisition. Here too, the basis is sensors that are distributed at different points depending on requirements and objectives. Sensors that monitor the motor speed of the electric drive motors, temperature sensors on the tools used or sensors that record the fill levels of auxiliary materials, operating fluids and lubricants are common here. The sensors are connected via interfaces to data acquisition loggers such as the Delphin Loggito. The measured values can be recorded decentrally and forwarded to DAQ software via LAN, USB or WLAN, depending on the IT architecture. The software can be located in the cloud or in the company's data center. In the DAQ environment, the individual machine data is compiled fully automatically - providing a very detailed insight into the exact processes on the machine. The use of the data acquisition logger as an edge device is particularly interesting here - considering that one machine alone can "produce" several gigabytes of data per working day, it is essential to relieve the available bandwidth for data transmission, especially for extensive monitoring tasks. However, the collected data is still worthless at this stage - as it only represents a collection of values in a database. It is only through the additional use of special software that the machine data becomes "digital gold" - precisely when the software turns the endless chains of numbers into visualized graphics, key figures and diagrams.
Software such as our ProfiSignal 20 takes users from measurement to detailed diagram display with just a few clicks, allowing complex and detailed process visualizations or the monitoring of running processes in real time - without effort and without programming knowledge! Complete monitoring - from the individual machine to the entire production hall - is easily possible with DAQ systems. And not just at the workplace, but completely independent of location. No matter where you are in the world: You always have your production with you. Use your smartphone, tablet or laptop to check the current operating parameters of individual machines or system parts at any time, call up exactly the measured values you are interested in with a click and display all relevant data on your own personal, customized dashboard. Or get a quick overview directly on site in your production hall: With the new, innovative SCACH function from Delphin, you can display the complete machine visualization on your mobile device - simply and conveniently by scanning a QR code on the respective machine.
