The Frequency Meter is used to indicate vibration frequency generated by vibrating drum systems during operation. It detects vibration signals and converts them into readable frequency values expressed as vibrations per minute. The meter allows operators or service personnel to observe vibration behavior without relying on complex measuring equipment. It is a low-cost measurement option where approximate readings are acceptable.Attributes:• Converts vibration signals into usable frequency values.• Operates as a low-cost alternative to advanced measuring tools.• Indicator can check revolutions per minute at cycles per second between 14 and 750. • Supports operational awareness of vibration behavior.Applications: The Frequency Meter is used on vibrating drum systems to measure vibrations per minute and observe vibration behavior during operation or basic inspection activities.
