How is vibration frequency commonly expressed?

• A. Hz
• B. CPM
• C. RPM
• D. kHz

Answer: (B)

Vibration frequency is commonly expressed in cycles per minute (CPM) because it quantifies the number of complete cycles of vibration that occur in one minute. This measurement is particularly useful in various industrial and mechanical contexts where it is essential to understand the vibrations of machinery and equipment over time. While Hertz (Hz), which indicates cycles per second, is a standard unit of frequency, it can sometimes be less intuitive in contexts where cycles are more commonly monitored over a full minute. Therefore, expressing vibration frequency in CPM can provide a clearer understanding of vibration levels and their implications for equipment performance and maintenance schedules. Other terms like RPM (revolutions per minute) and kHz (kilohertz) serve specific purposes and cater to different aspects of mechanical or electronic systems but are not as universally employed for describing general vibration frequency in the context of building maintenance and monitoring. RPM is typically used for rotational speeds rather than direct measurements of vibration frequency, while kHz refers to thousands of cycles per second, which is less common in typical building maintenance scenarios.
