Effective Error and Fault Diagnosis

Data Collection Helps Prevent Machine and Process Failures

Plant machinery and processes are usually controlled by PLC systems or industrial PCs. Digital and analog signals undergo complex linking via programmable procedures and algorithms. But what happens when the program fails to function in the desired way, or when sporadic failures and irregular patterns begin to occur? Effective analysis generally requires the acquisition of the relevant digital and analog signals in parallel to existing systems.

This is where Delphin products can be used for a much more detailed analysis. These professional measurement systems are capable of fast and parallel sampling of digital and analog signals, thereby detecting errors that would otherwise remain undetected. In combination with the Delphin software’s logic diagrams, analysis is easy. As Delphin’s North American Master Distributor, CAS DataLoggers offers you these powerful systems to help you get your application quickly started and smoothly implemented.

Data Recorder for Fault Diagnostics:

An ideal device for many machine monitoring applications is Delphin’s Expert Transient Data Acquisition System. This new device is able to transmit data to a PC via an Ethernet interface where it can then be saved and observed online. The Expert Transient is especially suited to the evaluation of pressure pulses, fast process monitoring and controller optimization. The device’s internal storage can be accessed using ProfiSignal Go and the data can be analyzed offline. A signal sequence diagram is especially useful in providing an overview of the chronology of a malfunction event.

Sampling of analog and digital measurement data is performed fully synchronously. The Expert Transient data logger can operate independently for the synchronous acquisition of transient and periodical processes. This enables precise identification of the sequence of events in a malfunction. The system is available in two versions with 8 or 16 synchronous analog inputs and 4 digital inputs and can be further extended if necessary.

Measurement data can be recorded either continuously or according to triggered events. The Expert Transient is equipped with powerful FPGA technology and is capable of synchronously acquiring and independently saving analog measurement data up to a sampling rate of 50 kHz per channel in combination with digital signals.

Applications without PC support can store up to 16 GB of data in the device’s internal storage. Parallel recording to a high-capacity external NAS device is possible, and the Expert Transient also features an optional Wi-Fi interface.

Application features:

  • Parallel sampling of analog and digital sensors and actuators
  • Synchronous sampling
  • High chronological sampling at µ-second resolution
  • Independent fault data acquisition even without PC support
  • Relevant and easy-to-follow data evaluation using logic analysis.

Analysis Software Included:

Delphin data loggers such as the Expert Transient come delivered with the powerful ProfiSignal Go software which enables recorded signals to be portrayed live in y(t) diagrams. Even large volumes of historical data are easy to analyze using ProfiSignal.

Channels are represented in a clear and intuitive operation in a Windows Explorer style, and all measured values can be transferred to online storage and will work on PCs or servers. Visualization and analysis are performed with the ProfiSignal software or OPC Server with any software, providing users with up to 1000x higher time resolution when compared against a SCADA system.

The Cutting Edge—Delphin DAQ:

Delphin data acquisition systems solve a variety of measurement and control problems in industrial applications. They feature different analog and digital I/O modules that can be used with a wide range of signal types including: voltage; 4-20 mA current; thermocouple; RTD; and resistance. Delphin data loggers also offer powerful alarm and programming capabilities allowing them to process measurements and initiate actions on their own.

Delphin systems can be used for local data acquisition and logging when connected to a PC; for remote unattended data collection connected the internet; or as stand-alone devices.
