What is a thermal image?
Thermal images are created by converting thermal radiation into a visible light image that we as humans can interpret. One important point to remember about thermal imaging is that it is a non-contact measurement of radiated energy in a very narrow wavelength band.

There are many ways to evaluate an IEPE (Integrated Electronic PiezoElectric) sensor, or accelerometer, either on its own merits or in comparison to similar competitive models found on the market. The most obvious is a paper comparison, using the spec sheet as a guide. Other options include acquiring the contending sensors and putting them to the test or obtaining word-of-mouth inputs, each of which will likely result in a different conclusion. The most common starting point, however, is a spec sheet appraisal.

A small number of semiconductor manufacturers have overcome the noise, bandwidth and g-Range shortcomings commonly associated with MEMS sensors used in Condition-based Monitoring (CbM) by producing several medium and high-performance MEMS vibration sensors with the latter being comparable to piezo accelerometers.
