(1) IN the preface to their book on “Electrical X Measuring Instruments,” the authors state that “some apology would seem to be necessary for issuing yet another book on electrical instruments.” It is ...

Columbia Research Laboratories has introduced the Model VM-300 vibration meter, a general purpose vibration-measuring instrument designed for periodic routine checks of industrial equipment where ...

Industries and R&D sites depend on sensors to measure, monitor and analyze vibrations. Unfortunately, the best ways to get accurate and repeatable vibration data are not clear to many engineers; they ...

Industry 4.0, also known as the fourth industrial revolution, is a term used to describe the current trend of automation and data exchange in manufacturing technologies, including the Internet of ...

Part 1 of this series addressed the advantages and disadvantages of various vibration sensors; Part 2 examined signal conditioning and system hardware selection and configuration. I’ll wrap up by ...

An event camera–based system, “Event topology-based visual vibrometer,” that measures vibrations of objects without physical contact. The image illustrates the measurement of a guitar string. By ...

Today, a vast number of micro-manufactured sensors, actuators and components vibrate at frequencies in the high MHz range. Some examples of these high-frequency vibrating systems include surface ...

The lining cavities in tunnels have strong concealment and pose significant risks, seriously affecting tunnel operational safety. Therefore, it is necessary to develop efficient and high-precision ...
