Well we now have the design plan for the sensor and at least a basic circuit. If we want to simplify the alignment of the sensors in a gradiometer setup I have a design idea.
In the science of measurement, metrology there is much talk about reference. So what is crucial in a gradiometer setup, the sensor core elements have to be aligned. With this in mind how can we build this into our gradiometer in the manufacturing step and ridding us of the alignment issue. Then we should ask ourself what is the shortest route between to places, a straight line. If we in the design of the gradiometer think of a tube of a certain lenght seated loosely in a jig with a pair of v-blocks and then string up high tensile strenght line (i.e. fishing line) in the center of this tube we have a perfect alignment reference. Now by the means of superglue, or similar adhesive, edgeglue the Vitrovac or metglas coreelements to the line at each end of the line exiting the tube, they are perfectly aligned! The next issue is how to fasten the core element to the tube, well use a suitable fixture that will attach (glued) to the tube and is having an area that get close to but not touching the core, glued to the line. The next step would be to use droplets of glue and fuse the core element and the fixture together. Build up with glue so that the core is ready to accept som enameld exciting and sensing copper coils. When cutting the line be careful to avoid the line snapping. Material of choice for the tube and fixtures should be of rigid and stable i.e. fiberglass or kevlar tubing, avoid the pvc route.
This gradiometer sensor tube should be fixed unconstrained inside a outer tubing.
Hope someone like the design, hope I can sketch up the jig and sensor fixsture later but have to find the time. If you build please tell and share your experiences.
