Machine Monitoring Using Analysis Prevents Failures
By: CAS DataLoggers
Plant machinery and processes are controlled by PLC systems or industrial PCs that link digital and analog systems into complex programmable procedures using deterministic algorithms. Organizations stand to lose a lot of money if the process gets fouled, causing failures and irregular production patterns to occur. It is impossible to manually acquire and analyze all the data fast enough because of the processing speed and the overall amount of data generated. Using a high-speed, machine monitoring data logger to acquire the physical data from a PLC, industrial PC, or directly from the machines and then analyze at real-time speed to determine a fault is the only option to prevent catastrophe.
Data Logging for Fault Diagnostics
An ideal device for many machine monitoring applications, the Delphin Expert Transient Data Acquisition System is a device able to synchronously sample each analog and digital input at speeds up to 50kHz each, independently determine if a fault has occurred in milliseconds, and then react accordingly by starting a shutdown sequence, activating a local alarm or sending an email notification to a desired email address.
Measurement data can be recorded either continuously or according to triggered events like the start of a process or when a threshold is reached capturing only the data that is of interest. Later analysis using a signal sequence diagram is especially useful in providing an overview of the chronology leading up to the fault.
The Expert Transient is equipped with powerful field-programmable gate array (FPGA) technology allowing quick program updates in response to local variables increasing its flexibility. The Expert Transient does not need PC support like most data acquisition systems because the internal 16 GB of memory allows for stand-alone operation while parallel recording to a high-capacity external NAS device is also supported, or the Expert Transient can be outfitted with an optional Wi-Fi interface.
Cutting Edge Data Acquisition
Delphin data acquisition systems solve a variety of measurement and control problems in industrial applications. They feature different analog and digital I/O configurations 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 making them perfect for process measurement and identification of fault events. Delphin systems can be used for local data acquisition and logging when connected to a PC, remote unattended data collection connected to the internet or stand-alone devices.
