I need a starting place to gather information on designing a custom flame arrestor. Small air/methane sampling line, would probably need to be flat plate style to minimize clogging, allow easy cleaning. (the sample is never clean gas).
Need to figure out spacing, length, size, etc... There...
unfortunately my target is suspended from a pulley system. an encoder or proxsensor solution on one of the pulleys or takeup drum is an option, but because of varying cable stretch and other unknowns an absolute position at any given time will be uncertain. I can't really have anything around...
I'm not sure on the numbers yet, I'm still very early in the design process, just trying to figure out if it can be done and how. But for an early guess...
accuracy: probably within an inch
speed: several times a second, maybe ~10? Faster is better, within reason(and cost)
motion: will be...
I have an application that requires accurate, reliable and continuous position feedback, in one dimension, range up to 30 meters. I need the sensor to give me absolute distance from a base point to the target. It's also going to be outdoors and in a high traffic area, so it'll definitely get...
Guess I wasn't clear enough. I'm not questioning the union itself, I'm talking about the two ends provided to join the union to your system, which often are LPT.

API 6A and ASME B31.1 tell me threaded connections should not be used over 5000 psi. (I'm using 2" XXS pipe) But I can go out tomorrow and buy a hammer union rated at 10000, or even 15000 psi, with LP threads on either end. Even with ideal inital assmebly, those threads are going to be...
