Infrared Thermography

Whether electrical equipment or rotating equipment such as centrifuges, gearboxes, and electric motors, infrared thermography is a technique that is proven to be essential in these components.

L&S Electric offers a detailed and comprehensive digital thermography analysis, which also features a list of Key to Severity items that include recommendations and classifications of problem areas.

Digital Thermography 

Photo of an infrared scan of electrical equipmentWe perform digital thermography, which determines any piece of equipment that has an existing issue. Furthermore, we offer a list that features "Key to Severity", and this includes general recommendations each time there is an increase in temperature. There is also a thermographic test point area that contains a detailed image and photograph of the problem area, as well as comprehensive information about it. 

All reports gathered are customized based on your needs. Included in the report are the following items:

  • Identification of certain points
  • Temperatures with graphical representation
  • Temperature display, which is superimposed over a particular image
  • Areas within a particular temperature band

IR Video: Real-Time Analysis

An IR video enables you to be aware each time there is an increase or decrease in your equipment's temperature. Hence, this tool can check any change in temperature within as little as 10 seconds – and this is something that you cannot achieve with IR still photo.

Thermographic Analysis Program

A long wave system is capable of measuring accurate temperature even in harsh conditions because of its minimal susceptibility to reflections.

Innovative Equipment

Long wave system, which is less susceptible to reflections, allowing accurate temperature measurement in adverse environments  Temperature measurements from -10 °C to +1500 °C with ±0.1°C accuracy  Scanning distances of up to 60 feet

On-Site Report
