Accurate Product Quality Testing for Fewer Failures



"No matter the manufacturing process, manufacturing companies can greatly benefit from accurate product quality testing and verification," said a CAS DataLoggers spokesperson. "This way, any failures can be caught as quickly as they are formed. However, the high variability in part formation makes monitoring values such as force and displacement difficult-the difference between a quality and defective part is often measured in milliseconds. Therefore, these demanding applications require a high-speed device to capture all the data to reduce the frequency of failures and the attendant shipping costs. CAS DataLoggers Application Specialists often recommend an automated set-up utilizing a Delphin Expert Series Data Loggers for accurate process monitoring."

Improving Process Monitoring

The Expert Logger performs feasibility investigation, for example by connecting to a pressure transducer that can monitor hydraulic presses and other parameters from part-forming machines. The Delphin Expert Logger monitors force, displacement, temperature and other parameters using real-time sampling in the 100-500 Hz range.

With the Delphin DAQ system, users now have the ability to sample quickly enough to detect force vs. time during the pressing operation, which is measured in fractions of a second. Potentially there are a number of failures that will create bad parts and still pass a limit test, so this exact timing and detailed information greatly improves process monitoring.

Delphin Expert Logger devices are specifically designed as universal input data loggers. As an example, the Delphin Expert Logger 100 is equipped with 16 analog inputs and a sampling rate of up to 1,000 measurements per second (aggregate).

The inputs can be used for data acquisition of mV, mA signals or any type of thermocouple, and all inputs have differential and galvanic isolation. The complete package consists of the Expert Logger device and ProfiSignal Software, enabling users to measure and analyze data immediately with no delays.

The Delphin Expert Logger works completely independently as a data logger for acquiring, monitoring, computing and storing measurement data. The internal data memory allows continuous recording of up to 250 million samples, and Expert Logger systems are available in eight different styles to suit individual process needs.

Higher Measurement Speed

In cases of linear displacement measuring and logging other values requiring a higher measurement speed, the Delphin Expert Transient High-Speed System is recommended. This data logger has an overall sampling rate of up to 50,000 measurements per second per channel (synchronous) that can accurately measure displacement and other demanding requirements. Any number of alarm and logic channels can be defined for the 8 or 16 analog inputs and 4 digital channels, and any of the system's 8 digital outputs can be switched regardless of the current alarm situation.

Tracking and Analyzing Software

A key advantage of the Delphin set-up is the ProfiSignal PC Software that lets users view and evaluate the data curves produced during the process to get a list of well-formed parts and their formation details. This professional software, used for online/offline monitoring and measurement data analysis is available in three versions: GO, BASIC and Klicks. Just three steps are required to display measurement data as trends, analyze the data and evaluate offline data. Additionally, ProfiSignal has a user-friendly interface that makes it easy to learn.
