Hi
I'm trying to measure a micro-level magnetic particle with the BMM 150 by directly placing it on top of the sensor.
to understand better how the Z-axis (Hall sensor) performs when the object we are trying to detect is off-axis vs on-axis and the distance etc.
could you please tell me whether there is a variation in sensitivity within the Z-axis sensing area?
I'm interested in finding out the information on the variation/drop-off of the output with respect to the following:
1. Angle of the object away from its ideal position (with constant distance i.e. radial position variation).
2. Distance of the object away from its ideal position (when the object is centimetres away from the sensor).
3. Distance of object away from its ideal position (when the object is millimetres away from the sensor i.e. very close proximity)
4. Are there any dead zones or areas of varying insensitivity including any dead zones based on angle etc.?
thanks
