    Automotive Hydrogen Car Fuel Tank: Preventing Permeation & Valve Check

    While I can't speak for valve manufactures, sensor manufactures plate their devices with gold or use other "super-alloys" (Elgiloy for example) to avoid the negative effects of hydrogen permeation. https://www.yokogawa.com/us/library/resources/application-notes/hydrogen-permeation/...

    What are optic fibres/cables in simple words?

    Yeah it is interesting how commercial applications of technology so easily overtake industrial applications, and then, hopefully, lead to rapid advances in said tech.

    Linear measurement of a curved part

    Are you manufacturing hundreds of these parts? And would they all need to be measured for accuracy? If so then then a Tom.G suggested, having some kind of jig built would be my suggestion, though I would use two laser distance sensors to give an accurate thickness, or in this case diameter, in...

    Automotive Designing a Poka-Yoke for Flat Marks on Rocker Arm Bearing

    Yes, sub millimeter is possible, budget allowing. Banner and keyence were mentiobed, link is to a 20um SICK device. On curved metal surfaces things can get interesting with optics, but you would have to try it out...

    Relay with High DC Breaking Capacity

    For an inductive load you would need a contactor with a sufficient AC-3 rating for your application, the link (http://electrialstandards.blogspot.co.za/2014/04/electrical-contactors-utilization.html) has a short explanation regarding AC ratings. Industrial suppliers like Siemens, ABB, Schnieder...

    Find 3D Printer & Software Resources for Prototype Creation

    I bought a fairly simple printer (TEVO Tarantrula) from AliExpress some time ago, it had some issues, but after a bit of patience and googling I have a device I'm quite happy with. As it came as a kit, I had to put it all together, and the devices themselves are really uncomplicated. Of course...

    Automotive Designing a Poka-Yoke for Flat Marks on Rocker Arm Bearing

    Hmm, first time I've heard the word/phrase/expression "poka-yoke" as well, either way... So if I understand correctly, you need to ensure that the bearings are circular without any flat spots? It is difficult to get into any specifics without understanding the application in detail, however a...

    What magnetic position sensor to choose?

    Hi, just so I understand, you are looking to measure sideways movement of a small object, "Head of a pin" this object can move up to 5mm from left to right (in relation to the sensors view point) I'm assuming the object cannot move up or down or closer or further away from the sensor? I cannot...

    Material selection for food grade application

    Hi, our company uses 316L for all its Food and Bev Grade (Hygienic) products. The two main reasons for this, as far as I understand, is that it can withstand the typical cleaning agents using in CIP (Clean in Place) processes, and that the surface finish is smooth enough to minimize the build up...

    Measuring the deflection of a beam

    I may be waaay of the mark, but this looks like you are taking the data from a LIDAR and are trying to normalize it's values into usable distance data?

    How can I modify a LM337 circuit to increase current output?

    So many moons ago I made myself a pretty bog standard dual linear bench power supply using an LM317 and LM337 to give me -15 - 0 - +15. In an attempt to get more current out of it (for no real reason other than because I can) I got a larger transformer and a beefier rectifier, then using the...
