Sensor and Target Evaluation  
Magnetic Profile  
A pair of curves can be derived from this map data, and be used  
to describe the tooth and valley magnetic field strength, B, versus  
the size of the air gap, AG. This allows determination of the mini-  
mum amount of magnetic flux density that guarantees operation  
of the sensor, so the system designer can determine the maximum  
allowable AG for the sensor and target system. One can also  
determine the TPOS air gap capabilities of the sensor by compar-  
ing the minimum tooth signal to the maximum valley signal.  
In order to establish the proper operating specification for a par-  
ticular sensor device and target system, a systematic evaluation  
of the magnetic circuit should be performed. The first step is the  
generation of a magnetic map of the target. By using a calibrated  
device, a magnetic profile of the system is made. Figure 10 is a  
magnetic map of the 8X reference target.
