DC Inductive Proximity Sensors

Introduction:
Inductive Proximity Sensors are the most widely used Sensor Technologies in the modern process control environment . The coil at the sensing face of the sensor is excited by a Sine-wave oscillator which produces an Electromagnetic field in the sensing face. When a metal object moves into the sensing range, due to Eddy Current effect, the oscillations are being dampened in the sensing circuitry. This change in status is detected by the detector circuit and is further processed by output logic driver section
