Re: Spacing between NCE BD20 detectors

Bill Wilken


I've tried a variety of "winding" strategies, but without success.  When I talked with NCE's technical support fellow the other day, he was pretty skeptical about the feasibility of 25' blocks.  He suggested that the only viable option was installing a POT on the BD20, which I haven't yet attempted.  In the meantime, I'm double-checking all my wiring.  My experience (successfully) building a test-bed tells me that it's all too easy to goober up connections.

Hi Bill,

If you haven't tried it already, try putting more than one turn through your BD20.  Literally just loop it around and go through it again.  This increases sensitivity of the BD20.  I don't think you need multiple detectors in a block.  Check the BD20 instructions for multiple turns through it.
