Field Wiring Field Wiring There are a number of items to consider when installing a permanently mounted vibration monitoring system. One of the most critical considerations is the selection and installati Flatness Measurement Application Note Courtesy of DamaliniFlatness Flatness measurement is done on for example machine tables, wire parties in paper making machines, flanges (circular planes), machine foundations etc FM / ATEX Comparison Chart A visual example comparing and contrasting Factory Mutual ratings and ATEX ratings. Frequency Domain Frequency Domain Frequency domain measurements and analysis have become increasingly popular to diagnose a particular machine fault. This measurement mode relies on proc Gardening: Lighting Terminology & Lighting System Comparisons Lumen: This is the basic unit of light. If you could grab a bunch of light in your arms, the term lumen would describe the amount of light that you have.

Understanding the technology Printable Version Intrinsic Safety – the basicsThe term “Intrinsically Safe” (I.S.) is frequently used to describe any product destined for an explosive area. In reality, I.S. is a protection concept IR Measurements and Emissivity IR Measurements and EmissivityA basic understanding of emissivity and reflectivity of materials is required for using and understanding Infrared temperature measurements. All materials emit thermal en IR Thermometers vs FLIR i-Series Infrared Cameras IR thermometers (a.k.a. temperature guns) may seem inexpensive and simple, but they only read one average spot measurement at a time, making them painstakingly slow when scanning multiple ISO 10816 Vibration Severity Chart ISO 2372 (10816) Standards provide guidance for evaluating vibration severity in machines operating in the 10 to 200Hz (600 to 12,000 RPM) frequency range. Examples of these types of machines are smal Journal Bearings Journal Bearings Industrial machinery with high horsepower and high loads, such as steam turbines, centrifugal compressors, pumps and motors, utilize journal bearings as rotor supports.
