Chemical Processing - June 2008 - (Page 25) properly interpreted; in some instances, it can help confirm a particular problem that simply may have been a “best guess” scenario. Time domain is the actual data received from machinery and further processed through Fourier Transform to arrive at the frequency domain. is allows personnel to discern actual frequencies and amplitudes of components within a machine and helps target components that may be failing or faulty processes that could have gone undetected until machinery failure. In general, the time domain is a record of events as they happen and is very similar to looking at recorded sound. A sine wave produced by a signal generator in the lab would appear in the time domain spectrum just as it does on the screen of an oscilloscope. In the real world, though, complications arise because a machine does not produce a solitary signal. at’s where a time domain signal shines. For example, an operating motor connected to a gearbox and then to a compressor produces thousands Data collector Figure 2.
