Greetings all; I have obtained a couple 0-10 psi 3 wire sensors I'd like to use to control a pwmgen to regulate the low air pressure a mister uses, as just a couple lbs is plenty. Useing a 12 volt supply driving 5 of those teeny compressors I bragged about finding.
But it has an unusual (to me) feed arrangement to get the pressure into it, seems to be a std in the auto world, but I've never seen it before. The thread is not a tapered thread, measureing 12.95mm in the threads major diameter, and quite close to 1mm pitch, maybe .98mm? There is a reduced diameter area between the inner end of the thread, and a smooth flat face beyond it, as if an O ring is intended to be sealed in position by having its outside contained in a rim around the socket it screws into. Has anyone a clue what this is known as in the trade? G1/4 seems to relate somehow, but its nowhere near a 1/4 inch AMSTAN pipe thread for pitch, and its not tapered like a pipe thread. Wikipedia.org wasn't much help as no common threads for about that size are anywhere near that pitch. There is a fine thread metric 12mm at 1mm pitch, but no 13mm seems to exist. Call me puzzled.
