Long-term and seamless recording with Expert Transient
Whether pressure pulse measurement, fault detection or sound distribution measurement: recording short-term events with high temporal resolution is a particular challenge for measurement technology. This is where transient data acquisition comes into play. Corresponding measuring devices are able to precisely record measurements with very high sampling rates, even signals and events in the sub-millisecond range.
Whether you need to record a spontaneous event or the continuous, uninterrupted recording of rapid physical or chemical processes, we are your competent partner. We offer you reliable solutions for investigating a wide range of non-periodic events where conventional measuring equipment reaches its limits.
What does transient mean?
The word transient is derived from the Latin "transire", which can be translated as "to pass" or "to pass by". It describes something temporary or spontaneous.
What is transient data?
Transient data is data that is recorded by a measurement system, ideally with pre- and post-history, during a short-term dynamic event. Transient events are characterized by rapid, significant changes in the measured values
What is a transient analysis?
Transient analyses examine systems, plants and processes during their transition phases with the aim of understanding their behavior during state changes. They make an important contribution to identifying potential weak points or critical phases within a system, as well as evaluating their impact on overall performance and system and process optimization. This form of analysis is indispensable when modeling the temporal behavior of systems - especially in electronics, mechanics, fluid mechanics and thermodynamics.
What are transient voltages?
Transient voltages are electrical voltages that occur in the course of transition processes in electrical systems. Typical causes are the switching on and off of devices, short circuits and lightning strikes. Transient voltages occur both in the form of overvoltages and in the form of voltage drops. Despite their short duration, they can reach high amplitudes and have a significant impact on the functionality of electrical systems and components.
What are transient processes?
Transient processes encompass the entirety of physical or chemical processes that occur during the transition from one stable state to the next. They can be observed in many technical systems - for example in electrical circuits, heat transfer, mechanical movements and fluid-dynamic systems.
How is transient data measured?
The measurement is usually carried out with transient recorders and fast data loggers with intelligent storage. These devices are characterized by high sampling rates and large storage depths. As a result, they are particularly precise and can store and analyze a large amount of data.
How does transient data acquisition help with troubleshooting?
Transient events in technical systems such as electrical networks, mechanical systems and industrial control systems can indicate problems that are difficult to identify. For example, a transient voltage spike can indicate the imminent failure of a component, an unstable power supply or an overload. By collecting and analyzing transient data, technicians and engineers can
- Recognize warning signals at an early stage before a failure occurs.
- Conduct root cause analysis to find the exact trigger of the transient event.
- Identify recurring patterns that indicate errors or weaknesses in the system.
Expert Transient, a transient recorder developed by Delphin for the synchronous recording of non-periodic and transient processes, provides valuable assistance in troubleshooting machines and systems.
What advantages does the Expert Transient data recorder offer?
Expert Transient enables the synchronous recording and independent, triggerable storage of analog measured values such as vibrations, pressures, shocks and forces. The intelligent measurement technology is easy to configure and can be used independently of a PC. As the measured values can be pre-processed and saved directly at the measuring point or recorded on external storage media, data storage is particularly secure.
Thanks to its small footprint, Expert Transient can be used in a wide variety of industrial environments. The low energy consumption ensures cost-effective operation. Thanks to a passive PROFIBUS sniffer, PLC signals can also be recorded. The measured values can be saved permanently or triggered. The trigger conditions can be set so that events and faults are captured and recorded with pre- and post-history.
Examples of the successful use of Expert Transient
With its fast acquisition of analog and digital signals, the Expert Transient for a wide range of applications. Among others, we have been able to implement the following applications to date:
- Troubleshooting for pressure surges in piping systems, e.g. in a dairy
- Monitoring and detection of anomalies in drives (of conveyor technology) and control systems, e.g. in mechanical engineering
- Synchronous detection of pressures and pressure surges, e.g. in chemical plants
- Monitoring of supply networks with regard to transient voltages (both overvoltages and voltage drops)
Other possible fields of application include crash, detonation and explosion tests as well as shock and vibration measurement. The transient recorder can also be used in materials research and environmental simulation as well as on test benches and in laboratory tests. For the latter two fields of application, the compact basic device equipped with plug-in clamps is usually sufficient. If your scenario is more demanding, we will work with you to find an individual solution tailored to your specific requirements.
