PPT-Optical Position Sensor:

Radiation Hard glasses for lenses and new electronics Jose Luis Sirvent Blasco Student meeting 26112012 1 Issues due to radiation A Lenses goes dark as they are irradiated Reduce the life time of the system. It is used for measuring targets made of electrically conductive materials which may be either ferromagnetic or nonferromagnetic A highfrequency alternating current flows through a coil cast in the sensor housing The electromagnetic coil field induc It is used for measuring targets made of electrically conductive materials which may be either ferromagnetic or nonferromagnetic A highfrequency alternating current flows through a coil cast in the sensor housing The electromagnetic coil field induc A high frequency alternating current is fed through a coil embedded in a sensor housing The electromagnetic field from the coil induces eddy currents in the conductive target As a consequence the alternating current resistance of the coil changes Th Two Types. Diode-Phototransistor Pair. Sharp Sensors. Sharp Sensor. Pros. Easy to use. Cons. Expensive. Large. Noisy readings. Diode-Phototransistor Pair. Pros. Cheap. Small. More accurate. Cons.
