High Accuracy and Fast Measurement

The FRQ-21 frequency meter delivers reliable and highly accurate readings, with an impressive accuracy of 0.1 Hz. Its advanced microcontroller-based system ensures rapid frequency measurement with a sampling time of less than one second, making it well-suited for real-time monitoring needs in industrial settings.


Robust Design for Industrial Environments

Built with a flame-retardant ABS plastic enclosure and copper conductors, the FRQ-21 is engineered to withstand demanding conditions within electrical panels. Its front panel protection class of IP20 and broad operating humidity tolerance (up to 95% RH, non-condensing) ensure a durable and safe measurement solution.


Simple Installation and Versatile Applications

This frequency meter features an easy panel mount design with 96 mm x 96 mm dimensions, allowing straightforward integration into electrical control systems. Compatible with both 110V and 230V AC rated voltages, it is ideal for a wide range of applications including measurement, control, and monitoring in control rooms and power distribution panels.

FAQ's of FRQ-21 Multispan Single Phase Frequency Meter:


Q: How is the FRQ-21 Multispan Frequency Meter installed in an electrical panel?

A: The FRQ-21 is designed for panel mounting, with standard 96 mm x 96 mm dimensions, making it compatible with most control panels. It features panel mount terminals and can be easily installed by following the wiring diagram provided in the user manual.

Q: What is the benefit of using a microcontroller-based frequency meter?

A: A microcontroller-based design, like that in the FRQ-21, enables precise and consistent measurement, rapid sampling, self-diagnostics, and long operational life. This ensures higher accuracy and reliability compared to analog meters.

Q: Where can this frequency meter be used?

A: The FRQ-21 is suitable for use in electrical panels, control rooms, and power distribution centers, making it ideal for utility companies, industrial facilities, and commercial environments requiring continuous frequency monitoring.

Q: What is the process for measuring frequency using this meter?

A: The meter directly receives the input voltage signal (110V or 230V AC as ordered), processes it through its internal microcontroller, and displays the AC frequency (45-65 Hz) on a clear 3-digit LED display, with updates in under one second.

Q: What is the operating environment for the FRQ-21?

A: This frequency meter functions effectively in ambient temperatures from 0C to 50C, withstanding humidity up to 95% RH (non-condensing), making it suitable for both standard and slightly demanding indoor conditions.

Q: How does the self-powered feature work on this frequency meter?

A: The FRQ-21 is self-powered, drawing its operating energy directly from the measured voltage input, eliminating the need for an external power supply and simplifying the installation process.

Q: Why should I choose the FRQ-21 over other single-phase frequency meters?

A: With its high accuracy, rapid response, ease of installation, wide voltage compatibility, robust design, and compliance with IS/IEC standards, the FRQ-21 offers a dependable, cost-effective solution for both routine and critical frequency monitoring tasks.
