Attached is a basic schematic of the transducer. Source of spike causing D1 to blow is not known. Original question
was concerning the susceptibility of a 2.4 zener vs a 3.6. Assume PIV are equivalent. Red is +28v in, green is +5v out...
Our firm is using a pressure transducer in an application and the circuit design
uses a 2.4 volt diode on the output. We have seen some of the diodes become blown due
to transient spikes. We know that at one point the manufacturer had considered a 3.6 volt diode
on the output. The question of...
We're using a dash size -202 insert in 7050 aluminum. We have the thread in the
aluminum block designed with an undercut at the bottom and the inserts
appear to be threading in and bottoming out past the undercut. We are seeing evidence that
after we drive in the two locking keys, which are...
A big THANK YOU to all contributors. We have a better understanding of the issue and have established a path forward.
This is a DOD part that is currently getting a lot of use so each improvement is greatly appreciated. [cheers]
Thanks. System design is tenuous, no doubt, but cost for a more robust solution and space constraints
really lock us in.
This has been helpful so far and confirmed some of what I was thinking. One other item
that was brought to our attention from a heat treat vendor was that our temperature...
A vendor wound a large lot of 302 SST springs about two years ago. Springs were stress
relieved by heating to 450°F for 30 minutes, work hardened by cycling to solid height 100 times,
vendor then measured load at working ht and then placed them on his shelf.
Two years later, vendor says loads...
