Anyone aware of an aerospace industry standard regarding the use of dash numbers for system configurations?
IIRC Rockwell, Boeing and LMS had something in their drawing standards that -6XX were flight configurations, -2XX were prototypes, -6XX were Structural test articles, etc. It was always...
My first unit works! 400 hp with no problems except I spec'ed the wrong joystick. My bad!
Now I am adapting to a mideast desert environment. There are two circuits, the primary is a closed loop system (3000psi/120gpm) and the secondary is open loop (various). Heatwise I'm fairly certain that I...
I have a GE Fanuc system with an outdoor operator's station. Installed in the station is a GE Fanuc Quickview Panel. Being outdoors the panel is occasionally subject to direct sunlight; long story short - they stop working when exposed to the sun.
I need a replacement panel that will hold up to...
I'm looking for a sensor that detects the presence of oil vapor, not necessarily a measurement of the amount present but that oil is present above a specified threshold. The application is in a 5000 psi Nitrogen stream. The oil contamination is 30Wt compressor oil.
My fallback position is to...
My new units need a hydraulic reservoir. The reservoir is mounted on the back of a tractor (truck) along with all my pumps. Hoses on a swivel hose carrier run between the resevoir and the trailer where the actuators are.
The size of the resevoir is about 350 gallons. This was selected by the...
I have several circuits comprised of a transducer providing a 4-20 ma signal to an electronic gauge. I'd like to capture that signal in a data acquisition system (DAS).
I have the design vendor looking for gauges with a data output, but in the meantime I thought I would inquire here.
My first...
I'm creating a syllabus for a course I have to teach in June to hydraulics technicians regarding troubleshooting electro-hydraulic systems. It includes reading schematics, multimeter operation, electro-hydraulic devices and simple DC electrical theory. When teaching basic DC electricity one...
The units I have operating (3000 psi/120 gpm) use hydraulic valves (proportion & directional)that are remotely piloted. I was going to build new equipment using the same configuration because I was not convinced that electrically controlled hydraulic valves were not as reliable. After talking...
This question applies to platforms on the Outer Continental Shelf. Clarification in [brackets] is mine.
Title 30 CFR Section 215.114 states
The question is: Are the results of these classifications made by the platform owner/operator filed anywhere?
I have the 500/505 and subsequently...
Well, I suppose I might as well step in it and display my ignorance.
I've been involved in flight simulators, spacecraft and automatic test equipment for 20+ years. The relevance here is real time control and monitoring of 1000+ sensors and effectors.
My recent endeavor is telemetering a...
In an attempt to bring our equipment into the 20th century I'm designing an integrated monitoring system that is used when the equipment is operating. At this point it is only monitoring, the next phase will move into control.
Aside from the monitoring of case drain flow that brought me to this...
Continuing the theme of flowmeters, does anyone have experience with magnetic flowmeters - particularly in hydraulic fluid?

This particular sensor requires conductivity > 10 uS and a Reynold's number greater than 4500. The Reynold's number can be met...
