00:00:15.640 00:00:15.650 infrared thermography what's hot in PDM
00:00:19.470 00:00:19.480 thermographic inspections have been used
00:00:21.519 00:00:21.529 for over 30 years as components in
00:00:23.170 00:00:23.180 preventive and predictive maintenance
00:00:24.460 00:00:24.470 programs in the hands of a trained and
00:00:27.070 00:00:27.080 experienced operator a thermal imager
00:00:28.960 00:00:28.970 can provide a wealth of information that
00:00:30.460 00:00:30.470 can improve efficiency productivity and
00:00:32.830 00:00:32.840 safety with interest in in thermography
00:00:35.830 00:00:35.840 and an all-time high and equipment costs
00:00:38.259 00:00:38.269 at record low prices there has never
00:00:40.420 00:00:40.430 been a better time to capitalize on the
00:00:42.009 00:00:42.019 benefits of an infrared inspection
00:00:43.570 00:00:43.580 program in this presentation we'll
00:00:46.570 00:00:46.580 explore some of the more common
00:00:47.950 00:00:47.960 applications of commercial and
00:00:49.750 00:00:49.760 industrial thermography what is
00:00:51.820 00:00:51.830 thermography infrared thermography is
00:00:55.149 00:00:55.159 the use of an infrared imaging system to
00:00:57.310 00:00:57.320 detect display and record thermal
00:00:59.859 00:00:59.869 patterns and temperature values across a
00:01:01.719 00:01:01.729 given surface the concept of
00:01:04.179 00:01:04.189 thermography is simple all objects above
00:01:06.700 00:01:06.710 absolute zero or zero Kelvin emit
00:01:09.280 00:01:09.290 infrared radiation while infrared energy
00:01:12.340 00:01:12.350 is invisible to the human eye it is
00:01:14.140 00:01:14.150 detectable with a thermal imager also
00:01:16.030 00:01:16.040 known as an infrared camera infrared
00:01:20.679 00:01:20.689 data can be observed in real-time or
00:01:22.599 00:01:22.609 captured to videotape PC card or
00:01:25.270 00:01:25.280 electronic media for post analysis
00:01:27.090 00:01:27.100 today's modern thermal imagers are video
00:01:29.830 00:01:29.840 camera like devices which often can fit
00:01:32.349 00:01:32.359 in the palm of your hand a thermal
00:01:34.929 00:01:34.939 imager converts the invisible infrared
00:01:36.489 00:01:36.499 energy into a monochrome or multicolored
00:01:39.219 00:01:39.229 image which represents the apparent
00:01:41.950 00:01:41.960 thermal patterns across the surface of
00:01:43.809 00:01:43.819 the object being inspected when recorded
00:01:46.660 00:01:46.670 on photographic film or paper these
00:01:48.880 00:01:48.890 images are referred to as thermal grams
00:01:50.859 00:01:50.869 many modern thermal imagers are also
00:01:53.109 00:01:53.119 capable of recording temperature as well
00:01:55.919 00:01:55.929 once captured thermal images and
00:01:58.629 00:01:58.639 associated temperatures can be stored
00:02:00.249 00:02:00.259 for future reference and analysis
00:02:04.139 00:02:04.149 infrared thermography is both
00:02:05.859 00:02:05.869 non-contact and non-destructive and for
00:02:08.529 00:02:08.539 inspections require no interruption of
00:02:10.090 00:02:10.100 service
00:02:10.860 00:02:10.870 additionally thermal imagers emit no
00:02:13.600 00:02:13.610 harmful radiation and are completely
00:02:15.460 00:02:15.470 passive
00:02:22.040 00:02:22.050 why thermography
00:02:24.410 00:02:24.420 as we move further into the 21st century
00:02:27.090 00:02:27.100 companies will continue to face the
00:02:29.130 00:02:29.140 demands associated with a global economy
00:02:30.949 00:02:30.959 these demands include increased
00:02:33.240 00:02:33.250 competition both domestically and abroad
00:02:35.520 00:02:35.530 as the world becomes smaller the number
00:02:38.190 00:02:38.200 of competitors expands no longer will it
00:02:41.130 00:02:41.140 be enough to be the most competitive in
00:02:42.780 00:02:42.790 the nation companies must strive to be
00:02:44.940 00:02:44.950 the best in the world in a global
00:02:48.630 00:02:48.640 economy companies must turn out the
00:02:50.220 00:02:50.230 highest quality products in an efficient
00:02:52.259 00:02:52.269 manner with less manpower while
00:02:53.970 00:02:53.980 remaining profitable oftentimes this
00:02:56.699 00:02:56.709 requirement is coupled with the prospect
00:02:58.979 00:02:58.989 of performing more maintenance tasks
00:03:00.900 00:03:00.910 with fewer personnel with these demands
00:03:05.220 00:03:05.230 in mind many companies are utilizing
00:03:06.600 00:03:06.610 predictive maintenance technologies to
00:03:08.309 00:03:08.319 help meet their objectives while
00:03:11.370 00:03:11.380 infrared thermography is one of the
00:03:12.630 00:03:12.640 newest non-destructive technologies it
00:03:14.670 00:03:14.680 can help to provide substantial
00:03:15.990 00:03:16.000 improvements in performance as well as
00:03:17.520 00:03:17.530 tremendous cost savings other proven
00:03:20.250 00:03:20.260 technologies include vibration analysis
00:03:22.199 00:03:22.209 oil analysis and ultrasound to name a
00:03:25.289 00:03:25.299 few
00:03:30.710 00:03:30.720 uses of thermography there are many uses
00:03:33.770 00:03:33.780 for thermography these include but are
00:03:36.260 00:03:36.270 not limited to preventive maintenance
00:03:39.730 00:03:39.740 predictive maintenance condition
00:03:42.980 00:03:42.990 monitoring forensic investigations
00:03:47.380 00:03:47.390 research and development and quality
00:03:51.200 00:03:51.210 assurance in short thermography may be
00:03:55.370 00:03:55.380 applied to any situation where knowledge
00:03:57.230 00:03:57.240 of thermal patterns across a given
00:03:58.790 00:03:58.800 surface can provide meaningful data
00:04:00.680 00:04:00.690 about a structure process object or
00:04:03.320 00:04:03.330 system thermography is a growing field
00:04:06.050 00:04:06.060 where new applications are constantly
00:04:07.610 00:04:07.620 being developed the use of thermography
00:04:09.470 00:04:09.480 is often limited only by one's
00:04:11.210 00:04:11.220 imagination common industrial
00:04:18.199 00:04:18.209 applications as stated previously
00:04:20.599 00:04:20.609 thermography can be applied to a wide
