Signal Flow in the Current Torque Metering Systems
- Monitor provides variable DC output to ESC.
- ESC generates AC and drives the stator power coil.
- Rotor power coil energizes the in-shaft electronics.
- In-shaft electronics power strain gages.
- Strain gages output voltage proportional to torque.
- In-shaft electronics convert voltage to frequency.
- Frequency is driven into rotor signal coil.
- ESC adapts to signal coil level and converts levels for long distance transmission.
- ESC converts Hall-Effect sensor signal levels (pulse per rev) for long distance transmission.
- Monitor receives the torque signal, counts the pulses (measures the frequency).
- Monitor receives the RPM signal, counts the pulses.
- Monitor converts the frequency to a torque value using calibration data.
- Monitor converts the pulses to an RPM value using calibration data.
- Monitor converts units and displays values.
- Monitor scales and outputs 4-20mA values.
