Data acquisition in process measurement
Process measurement technology is an important area in industrial automation. It includes the measurement and monitoring of various process variables such as temperature, pressure, flow, level and pH value. It is important that the measuring devices are precise and reliable in order to deliver accurate measurement results. They must also be robust and durable in order to withstand the demanding conditions in industrial environments. The measurement data is recorded in real time and can be used to control and regulate processes. Effective process measurement technology makes a decisive contribution to the optimization of production processes, quality assurance and safety.
In the field of process measurement technology, mA or mV sensor signals with limited temporal resolution are usually recorded. Higher demands are placed on the acquisition of transient processes or vibrations. The data acquisition rates are significantly higher and the evaluation is demanding. In most cases, systems from different manufacturers are therefore required. These then do not work together optimally. Delphin offers the ProfiMessage series is a system that is ideal for measuring standard signals. In combination with a Expert Vibro all data can be recorded, calculated, monitored and stored with one system. All measured values have the same time base and are therefore directly comparable with each other.
Application highlights of process measurement technology
- Acquisition of mV, mA and IEPE, ICP signals in one system
- No interface problems, as everything is in one system
- Vibration measurement can be integrated into process measurement technology at an attractive price
- ProfiSignal software suitable for evaluating and monitoring all measured values
- Secure, coherent data storage
Practical example in process measurement technology
Measurement of winding temperatures
In addition to shaft vibrations, winding temperatures are also recorded at many hydropower turbines in Switzerland. Message devices are used that are equipped with I/O modules for multi-channel Pt100 temperature measurement and shaft vibration inputs at the same time. Up to 16 oscillations and the same number of temperatures are recorded in one system. All in one system. This is a great advantage for the customer. With many other vibration measurement systems, the addition of process inputs is much more difficult or not possible at all. As both the Expert Vibro and ProfiMessage devices have two PROFIBUS interfaces, they can also be easily connected to a DCS system. With its solutions, Delphin offers special added value here.
