Magnetic  Sensor

Design uses a  Honeywell 2SS52M magnetoresistive sensor currently available  from  both Mouser and  Farnell electronics. Minimum sensitivity is 25 Gauss 2.5mT, which is at least two orders of magnitude  better than Hall effect sensors. Sensitivity is further improved  by  using  a  ferrite bead near the sensor  to concentrate  the  mangetic field. The  sensor is  activated  using a  rare earth  magnet, typical  operation range is 50mm.

We now have a set of magnetic sensors fitted in Wellington Cathedral. Thank you very much for your time, help and advice. I've attached a few pictures of what we ended up with if you're interested.
