PROXIMITY SENSOR METHOD AND APPARATUS THAT IS INSENSITIVE TO TEMPERATURE, NOISE AND LENGTH OF WIRE
A proximity sensor for determining the gap between a sensor and a metal target which is insensitive to noise, changes in temperature of the sensor and different lengths of wire by measuring the AC conductance, DC conductance and susceptance of the sensor and using the measured values with a predeter...

| Zusammenfassung: | A proximity sensor for determining the gap between a sensor and a metal target which is insensitive to noise, changes in temperature of the sensor and different lengths of wire by measuring the AC conductance, DC conductance and susceptance of the sensor and using the measured values with a predetermined data base to derive the desired gap distance. |
