<HTML>Right now on Ebay there are pressure transducers for sale at a reasonable price and of exceptional quality. They are available from 750 to 2500 psi with 3/8 flare fittings, with ss bodies and some even have gold contact pins. I bought 8 of them for less than 20 bux each after shipping. It is a dutch auction and it has been going for a while so there must be quite a few available. They use 28 volt supply and output a dc voltage proportional to the pressure and the specs come with them. For those of you wanting to eliminate those mechanical pressure switches with precision electronic controls, here is a good place to start.
