22.5mm Panel LED Indicator -Frequency Digital Indicator

Precision Hz Measurement Display for Power and Signal Monitoring

The Frequency Digital Indicator provides accurate frequency measurement for AC power systems, motor drives, and signal monitoring applications. This specialized digital meter displays real-time frequency information essential for power quality monitoring and process control. Critical for monitoring generator stability, variable frequency drives, and rotating machinery, this meter ensures optimal performance and helps prevent equipment damage from frequency deviations in industrial power systems and precision control applications.

Key Features

This digital frequency meter delivers precise frequency measurement with 0.01 Hz resolution for accurate monitoring. Wide measurement range from 0.1 Hz to 999.9 kHz accommodates both power frequency and high-speed signals. Multiple input modes include AC voltage, current transformer, and proximity sensor signals. Auto-ranging capability automatically selects appropriate measurement scale. Bright 4-digit LED or LCD display ensures visibility in all lighting conditions. Standard 22.5 mm or custom panel mounting for universal installation. Programmable frequency alarm setpoints detect over/under frequency conditions. Over/under frequency detection with relay outputs enables automatic control actions. Input voltage range from 80-300V AC or 5-60V DC signal compatibility. IP54-rated front panel protection against environmental conditions. Response time adjustable from 0.1 to 10 seconds for stability. Peak frequency capture and hold functions record maximum frequency. Microprocessor-based measurement provides stable readings even with noisy signals. Digital filtering eliminates false readings from harmonics and electrical interference.
