Sensor Model 10

  • 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 calculate Vp Amplitude)
  • Measures SynchroPhasors at Specified Intervals
    • PPS (Pulse Per Second, GPS) Synchronization on an External Interrupt Pin
    • Host syncrhonization
  • Internal EEPROM Stored Configuration
  • For Control Output Set Points for Red/Green LED Indicator
  • Synchronized Data Transmission of Every Sample Using RS232 in Streaming or Demand Text or Binary Data Modes at 115200 bps
    • Options for Streaming Text or IEEE C37.118-2005 binary output.



  • Displays Data in a Console

GridTrak PHzSensor Model 10 Work in Progress

Updated Feb 4, 2011

Project Files

Version 10.000, June 17, 2010

Note: The Model 10 uses the Model 9 PCB. The external 24LC1024 EPPROM needs to be removed from its socket for use with the firmware for the PHzSensor Model 10.
