Line Frequency Monitor
The Line Frequency Monitor is a precise and reliable microcontroller-based instrument designed for accurate measurement of main line frequency. With an accuracy of more than 0.02%, it ensures grid stability and optimizes power generation and synchronization in power generation and load dispatching centers, process industries, and other critical environments. Equipped with advanced accuracy capabilities of up to 2 decimal places (or up to 3 decimal places for the made-to-order version), this essential tool provides precise frequency monitoring for efficient operations.The 7-segment LED display, available in sizes from 4 to 12 inches, offers easy readability of real-time frequency measurements. Its robust design, wide operating voltage range, and suitability for power plants, manufacturing facilities, and research laboratories make it the ideal solution for accurate line frequency monitoring.
