Features

Sensor Model 9

  • Measures the Frequency of Every Cycle
    • 1/24,000,000 Second Resolution = Frequency Measurement Precision of 6 Significant Digits or +/- 0.00015 Hz
    • Frequency Measurement at 2.5V Reference
    • Frequency Measurement at Zero Crossing
    • Zero Crossing Delta Measurement = Time Between +2.5V to -2.5V (used to measure Vp Amplitude)
  • Internal EEPROM Stored Configuration
  • Optional External EEPROM for Event Recording (on battery backup)
  • For Control Output Set Points for Red/Green LED Indicator
  • Data Transmission of Every Cycle Using RS232 in Streaming or Demand Text or Binary Data Modes at 115200 bps
    • Options for Step Mode Transmission after a set of cycles for Raw, Average, and Mean Frequency for each set.
  • PHzMonitor Model 9 - Frequency Measurement Modes of Operation Details
