Features
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.

GridTrak PHzSensor Model 10 Work in Progress
Updated Feb 4, 2011
- This project has been moved to openPMU on Codeplex.com
Project Files
Version 10.000, June 17, 2010
- ExpressPCB Files (posted here for reference only, consider the openPMU design moving forward): File:PHzMonitor Model 9B ExpressPCB.zip ver 9.100 *
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.
