Waross, That sounds wonderful provided there are no significant supply voltage drops at each chain link; if I understand your recommendation then it should be alright as it would just be the (resistance of the wire+connections)*(n legs) for the worst case of the final link. I want to avoid...

Bill, Thanks for the input. We have considered an approach using conditioning electronics before we go through the wall (possibly multiplexing the sensors to even reduce the signal wires) but nixed it due to corrosion concerns/ignition protection concerns with PCBs on the "dirty" side. I can...

I am currently laying the ground work for the mechanical design of a new product for which I am in charge of many electromechanical interfaces, which additionally means I will be specifying our wiring harnesses. Given: 1) Various 5VDC sensors on a regulated line 2) Sensors have a ratiometric...

I see this as pretty black and white, as in I've received training that did not require me to participate. Presentation is showing "what" Training is showing "how" Presentations explain you or some work you did, some "thing" to the listener Training empowers the listener to reproduce...

Thanks for the links - great info Cheers

You could always test them. Knowing: 1) Specific gravity of your media Observing: 1) inlet pressure 2) outlet pressure 3) flow through valve 4) temperature You can calculate for these values although maybe I should assume that since you need to calculate these values you have no way to test...

TVP - I am not contradicting, I am looking for clarification & information to steer me in the right direction here. Compass Guide for metals has 3003 rated AB to 100% @ 90°F for Methanol, and as far as I can tell 3003 differs from 6061 in that it has less Cr, less Zn and no Ti. I'd imagine then...

valvit pretty much hit the nail on the head one addition however - I've used many thermoplastics & elastomers in hydrogen gas sealing applications, and even the thermoplasic/elastomeric seals become succeptible to explosive decompression due to the nature of the tiny molecules (or the ioinc...

Hansen, In general, a servo valve and/or a proportional valve is a variable restriction. They will control both pressure and flow. The question is actually in regard to how your controls are set up. You can close the loop on pressure or you can close the loop on flow. There are physical...
