What is infrared radiation?

People can only see only a small portion of the radiation that makes up visible light. The balance of the electromagnetic spectrum is made up of gamma rays, x-rays, ultraviolet, microwaves, infrared and radio and television signals. The infrared wavelength is longer than light wave but shorter than radio waves.

What is infrared thermography?

Infrared is an invisible portion of the light spectrum extending from 0.75 to 1000 microns. All objects warmer than absolute zero (0 Kelvin or –275.15 centigrade) emit energy somewhere within that range. The warmer the object, the brighter we see it with an infrared thermal imager.

What is a radiometric infrared thermal imager?

A radiometric infrared thermal imager is a device that makes a visual image of the infrared thermal patterns and is calibrated to take temperatures in a small area at various ranges.

What is a thermographer?

A thermographer is a thermal evaluator and imaging expert. Thermographers have a solid understanding of heat transfer laws, thermal dynamics and properties of materials and why they appear hot or cold.

Which diagnostic tool is better: infrared thermography or airborne ultrasonics?

Infrared thermography and airborne ultrasound (which detects high frequency sounds above human hearing) often compliment each other. For example, a faulty high voltage electrical connection will often produce detectable ultrasound (destructive corona) before it generates enough heat to be detected by a thermal image. Likewise, thermography can pinpoint thermal variances that ultrasound may have never detected.

What types of industries or operations use infrared thermography?

- Automotive maintenance and quality control departments
- Building envelope diagnostics
- Electrical inspections
- Mining
- Pulp and paper mills
- Steel mills
- Firefighting operations
- Food processing
- Property management
- Military

Do I need to shut down my equipment in order to have an infrared inspection?

No, in fact, all equipment must be operational during the inspection. Your electrical/mechanical equipment should be under full load during the inspection. The higher the current flow, the more power will be dissipated.

Our equipment is new. Is there any reason to thermally inspect it?

Unfortunately, age has no relationship to hot connections. Poor initial installation has been the cause of many catastrophic failures.

What is airborne ultrasound?

Airborne ultrasound is one type of ultrasound that has practical applications in the energy management and maintenance programs. This sound waves are low energy and have short wavelengths making them easy to locate with an excellent detector and knowledgeable inspector.

What are the applications of airborne ultrasound in my plant?

Airborne ultrasound is useful in finding gas leaks (compressed air and any other gases), either in a positive pressure or in a vacuum environment. It is also useful in checking the status of a valve for flow or no flow situation, check the operation of steam traps, monitor the condition of bearings, and in electrical inspection to detect the presence of corona, tracking, and arcing discharge. Airborne ultrasound is also useful in lubrication program to avoid over or under lubrication.

Do you provide ultrasound inspection services?

Yes. Our inspectors are experienced and certified in this field. We provide Air Leak Survey which includes a comprehensive reporting that shows tag number, location, description, CFM lost, and $ wasted. We also provide Steam Trap Survey, Ultrasound Bearing Inspection, Ultrasonic Electrical Inspection, and Lubrication. All the services include comprehensive reports.

What is vibration analysis?

Vibration analysis is a systematic method of diagnosing the condition of your mechanical equipment by analyzing its “back and forth” or cyclical movement.

What causes my machine to vibrate excessively?

There are many reasons why a machine vibrates excessively. Most common reasons are misalignment, hydraulic forces, imbalance, gear problems, worn belts and pulleys, bearing defects, bent shafts, etc.

What methods do you use in doing a vibration analysis service?

Depending on the situation, we can use a barcode, a magnet, a triaxial sensor or a single-axis accelerometer. We use the DCX unit from DLI Engineering with the Expert Alert.

Can we purchase equipments from you?

Absolutely! We have done the homework of choosing the right equipment that will give us the best value and reliable results for our customers. We sell DLI Engineering’s portable and online vibration analyzers, FLIR’s infrared cameras, SDT’s ultrasonic equipment, and Oil Analysis kits. We also carry the iLearn interactive programs.

Do you provide training?

Yes, we do. Our training methods are optimized to our students’ maximum learning and retention. We incorporate the practical experiences from the field, proper inspection techniques, and correct use of equipments. We offer certification trainings, in-house trainings, and software based trainings using iLearn Program.
