Frequency meter

Expanded Technical Specification: Frequency Meters

This product line encompasses two specialized frequency measurement devices: standard frequency meters and vibrating reed frequency meters, engineered to accurately monitor AC power grid frequency across diverse industrial, commercial, and utility applications. Both variants offer configurable frequency ranges and wide voltage compatibility to match different system requirements.

product details

Product Overview

1. Standard Frequency Meter
1.1 Measuring Range (Frequency)
The meter supports three selectable frequency measurement bands to cover global grid standards and frequency fluctuation scenarios:
● 45 ~ 55 Hz (optimized for systems with nominal 50 Hz frequency)
● 45 ~ 65 Hz (broadband coverage for 50 Hz and 60 Hz mixed systems)
● 55 ~ 65 Hz (targeted for systems with nominal 60 Hz frequency)
1.2 Rated Voltage Input
Compatible with a comprehensive range of standard AC system voltages, eliminating the need for external voltage transformers in most applications:100 V, 220 V, 380 V, 400 V, 440 V
This wide voltage compatibility ensures seamless integration with single-phase and three-phase AC power systems.

2. Vibrating Reed Frequency Meter
2.1 Measuring Range (Frequency)
Mirroring the broadband flexibility of the standard model, this vibrating reed meter is calibrated for the following frequency bands, leveraging resonant reed technology for intuitive, real-time frequency indication:
● 45 ~ 55 Hz
● 45 ~ 65 Hz
● 55 ~ 65 Hz
2.2 Rated Voltage Input
Supports a distinct voltage range tailored to its reed resonance design, suitable for both low-voltage and industrial-grade systems:50 V, 100 V, 220 V, 380 V, 440 V
2.3 Reed Arrangement & Functional Configurations
The vibrating reed frequency meter is available in two reed layout designs, each optimized for specific measurement tasks, with customizable orientation options:

Single Row Horizontal Reed Configuration
● Primary Application: Dedicated to direct frequency measurement of a single AC power system, covering the 45 ~ 65 Hz range.
● Customization Option: Vertical reed arrangement can be provided upon customer request, for installations with space constraints or specific visual alignment requirements.

Dual Row Horizontal Reed Configuration
● Primary Application: Designed for frequency comparison between two electrically isolated AC power systems. This configuration enables simultaneous visual verification of frequency consistency, critical for scenarios such as system synchronization, parallel operation of generators, or cross-grid frequency monitoring.
● Customization Option: Vertical reed arrangement is available upon request, to suit specialized panel mounting layouts.
