Capacitor Ripple VTANK VDEMOD Figure 7. Output Pulse for an 8 Tooth Gear VOUT1 VDEMOD The feedback potentiometer connected between OSC and RF is adjusted to achieve a certain detection distance range. The larger the resistance the greater the trip−point distance. (See Figure 4.) Note that this is a plot representative of one particular set−up since detection distance is dependent on the Q of the tank. Note also from the graph that the capacitor voltage corresponding to the greatest detection distance has a higher residual voltage when the metal object is well outside the trip point. Higher values of feedback resistance for the same inductor Q will therefore eventually result in a latched−ON condition because the residual voltage will be higher than the comparator’s thresholds. As an example of how to set the detection range, place the metal object at the maximum distance from the inductor the circuit is required to detect, assuming of course the Q of the tank is high enough to allow the object to be within the IC’s detection range. Then adjust the potentiometer to obtain a lower resistance while observing one of the CS209A outputs return to its normal state. (See Figure 5.) Readjust the potentiometer slowly toward a higher resistance until the outputs have switched to their tripped condition. Remove the metal and confirm that the outputs switch back to their normal state. Typically the maximum distance range the circuit is capable of detecting is around 0.3 inch. The higher the Q, the higher the detection distance. |
