    electronics generate the precisely timed interrogation signal and convert the internal timing measurement to the desired output. The output can be either an analog voltage, a current value, digital pulses in the form of serial data, or even highspeed industrial-network bus communication. The position (X
  • Sensor Sense: Hall-effect current sensors
    sensor completes the magnetic path and helps concentrate the magnetic field through the sensor. The sensor produces an output voltage directly related to the strength of the magnetic field generated by the current flowing through the shunt. Many such sensors operate from a single 5-Vdc supply so
