C02 Line Frequency Monitor
C02 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.
Features
• Measures line frequency accurately up to 2/3 decimal places
• No calibration required. Easy plug and play operation
• Large display visible from distance
• Non blinking display
Industry Use Case
1. Power Generation and Distribution: Ensuring grid stability and accuracy by monitoring line frequency in power generation and distribution processes.
2. Manufacturing and Industrial Automation: Enabling precise synchronization and timing for machinery coordination and process control in manufacturing and industrial automation.
3. Research and Laboratory Applications: Providing accurate frequency measurements for instrument calibration and studying frequency effects in scientific experiments.
Applications
• Frequency of power generation turbine
• Power Plant Control Rooms
• Power Distribution Centers
• Verify accuracy and stability of synchronous motors and clocks
• Monitor frequency of mobile and portable generation under load
• Continuously monitor frequency in laboratories during experiments and calibration processes
