Human vision is limited to a very small portion of the electromagnetic spectrum. Thermal energy has a much longer wavelength than visible light. So long, that the human eye can't even see it, just like we can't see radio waves.

With thermal imaging, the portion of the spectrum we perceive is dramatically expanded, helping us "see" and "measure" thermal energy emitted from an object. Unlike visible light, in the infrared world, everything with a temperature above absolute zero emits heat. Even very cold objects, like ice cubes, emit infrared. And visible light doesn't affect the thermal world, so you can see equally well in highly lit and totally dark environments.

Vibration analysis consists in listening inside the machine. Each component vibrates differently and generates a characteristic noise that leaves a typical fingerprint in the spectrum in the form of a linear pattern. If damage is present, the pattern stands out from the noise floor. This allows the specialist to recognize, for example, whether the problem comes from unbalance, misalignment or bearing damage. In addition to an accurate diagnosis it is generally also possible to determine whether urgent action is necessary or whether it can wait until the next scheduled servicing.

Condition Based Monitoring (CBM) is a type of predictive maintenance that involves using sensors to measure the status of machinery over time while it is in operation. The data collected can be used to establish trends, predict failure, and calculate the remaining life of machinery.

Unbalance is the most common cause of damage in rotating machines. It can be found in fans, ventilators, belt pulleys and couplings. The enormous centrifugal forces resulting from the uneven mass distribution generates high vibrations during rotation, which affects the entire machine construction. This can cause bearings, seals and couplings to wear prematurely or even fail.

An unbalance is easy to detect in the vibration spectrum because it vibrates in sync with the shaft rotational speed. Its energy is concentrated at the first harmonic spectral line. This can be remedied by balancing the installed rotor with a portable balancer, a process known as field balancing.

Rotating machines are prone to misalignment. Correctly aligned and regularly controlled machines significantly reduce operating and maintenance costs. Conventional methods for shaft alignment, such as straightedge, thickness gage or dial gage, are very time consuming. The quality of the results also highly depends on the experience of the operator.

UE Systems has produced thousands of ergonomically designed portable, and incredibly accurate airborne/structure borne ultrasonic instruments. Used primarily for leak detection, mechanical analysis and electrical inspection, these instruments have saved our clients tens of thousands of dollars in premature failure detection, elimination of downtime, increased productivity, and overall replacement costs.

UE System’s digital Ultra probe® instruments are supported by Ultra trend DMS, powerful data management software that fully integrates all inspections for effective plant-wide reliability and energy conservation. In fact, this patented software is the first of its kind to report both cost and carbon footprint reduction while enabling users to analyze, repair and report their savings.

So whether you require instrumentation for a simple or robust predictive maintenance program, need safe, reliable equipment for hazardous areas, or want assurance that your reliability program is working around the world, UE Systems can help you become more productive and profitable.
