Digital data acquisition on the PC - Efficient solutions for precise and fast data acquisition
Today, the digital acquisition of measured values on a PC is an indispensable tool for users in various industries, such as laboratories, test bays and service. It not only enables precise and seamless data acquisition, but also simplifies the evaluation and visualization of the acquired data. With the right data acquisition devices and software solutions, you can not only save time and money, but also significantly improve the quality of your measurements.
What are the advantages of recording measured values on a PC with Delphin?
- Real-time analysis: The measurement data is immediately available for processing and analysis, so that real-time analyses and visualizations (e.g. diagrams) can be carried out directly on the PC.
- Continuous recording: Measurement data can be recorded automatically and continuously, which is particularly advantageous in service life tests.
- Trigger and event control: Modern DAQ systems can be configured so that they automatically react to certain events (e.g. limit value violations), issue an alarm and record the data.
- Complex calculations: With suitable measurement software, the recorded data can be processed, analyzed and graphically displayed directly on the PC.
- Simple archiving: Digitally recorded measurement data can be easily stored, archived and retrieved as required.
- Traceability and transparency: Historical data can be easily tracked and it is possible to access older measured values at any time.
- Integration into higher-level systems: Delphin measurement data systems can be easily integrated into other systems (e.g. SCADA, ERP).
- Optimized processes: The faster availability of data means that production and research processes can be designed more efficiently.
Our data loggers are used in various areas to record measured values on a PC in order to collect and analyze precise data and to control processes. Typical areas of application are
- Measurements in laboratories and at test stands
- Mobile measurements in commissioning and maintenance
- Temperature measurement from thermocouples and RTDs
- Measurement of electrical units such as current and voltage
- Pump and motor test benches
- Flow measurements
Practical example of measured value acquisition on a PC
Long-term testing of DC motors
Continuous monitoring using Expert Key devices in a test stand for brushless DC motors. Currents and rotations are recorded on more than 100 test samples and transmitted to a PC via a LAN. Monitoring then takes place of peak values and motor failures. All measurement data is portrayed and visualised in trends using the ProfiSignal Klicks software. Alarm lists enable easy processing of errors and failures. In this application, DC currents undergo high-speed sampling at 10kHz channel. ProfiSignal automatically computes RMS values and time-signal processes. Relatively slow measurements of rotation signals takes place simultaneously within a single system.
