Application Notes and Case Studies
|
|
|
Many predictive maintenance (PdM) programs use thermography to monitor the apparent temperatures of operational equipment, using the heat values to detect and avoid equipment loss. |
|
|
|
|
A sensible approach to a steam system management program is to establish repair priorities based on safety, steam/energy loss, and possible impact on production and quality loss. |

|
Using a handheld thermal imager, you can capture infrared temperature measurements of a motor's temperature profile as a two dimensional image. |
|
|
|
|
Thermal images of electrical systems can indicate the operating condition of the equipment in those systems. |

This article reviews the fundamental causes of overheating, as well as, the tests and tools commonly used to uncover overheating problems. |

|
|
In most cases, if only because of their high operating temperatures and their capacity to cause injury or death as a result of some failures, furnaces and boilers should be included in predictive maintenance (PdM) programs that monitor their condition while they operate. |
|
|
|
|
While many people in the power generation industry are familiar with annual infrared thermography surveys as part of PdM, the coal plant in this case study uses a thermal imager year round. There are two differences in their approach. |

|
|
In energy audits of homes and other buildings, technicians use blower doors in conjunction with thermal imagers. The blowers create positive or negative pressures within interior envelopes, making leaks much more apparent in thermal images. |

Surface temperature can tell you a lot about a building's structural elements, plumbing installations, and HVAC and electrical systems. Problems that are otherwise invisible to the naked eye are suddenly clear as day when you look through an infrared lens. |

|
This brief introduction to thermal imagers is offered to present the potential user some insight to typical applications and may spark ideas for additional uses. |
|

|
This document discusses the cost savings of thermal imaging (thermography) PdM, provides guidelines for successfully capturing and analyzing thermographic data and describes how to integrate thermography into a predictive maintenance program. |
|
|
|
|
Electrical contractors typically use thermal imagers for predictive maintenance and troubleshooting, and sometimes during installation. | | |
