The Use of Thermal Imaging as a Diagnostic Tool for Hydraulic Systems
Hydraulic systems are an integral part of many mobile and fixed machines. Because hydraulic components generate heat during normal operation, they are excellent subjects for thermal imaging. Quite often, failures in hydraulic systems are accompanied by a change in operating temperature. When hydraulic components are visually accessible, thermal imaging and non-contact thermometry can provide valuable data for system diagnostics. This paper will discuss the theory and operation of hydraulic systems, common system failures, and the proper application of thermal imaging for hydraulic system diagnostics.
Infrared Inspections of Arc Fault Circuit Interrupters
Excess heating is often a sure sign of defective electrical equipment; however, the absence of heat can also be a sign of component failure. In this Tip, we demonstrate how thermal imaging may be used to detect defective Arc Fault Circuit Interrupters.
Burlington, NJ February 6, 2017 – Infraspection Institute’s annual IR/INFO conference was recently held in Orlando, FL. IR/INFO 2017 marks the 28th anniversary for the advanced training conference, technical symposium, and technology expo.
Thermal image shows a large warm area on a low slope roof that is being imaged from the rooftop. The yellow and pink rectangular shapes are caused by moisture within the highly absorbent insulation located beneath the roof membrane. Image taken during evening hours under calm weather conditions. Taken by John Gutierrez, this thermal image was the 1st Place winner - Roof Category in the annual Image Contest held during the IR/INFO 2017 Conference.
