Connect pressure transducer o/p to gauge?

AI Thread Summary
The discussion revolves around connecting a pressure transducer's output wires to a pressure gauge in an experimental setup. The original poster is considering using a pressure gauge instead of a transducer due to cost concerns, as they only need to measure pressure without controlling it. There is confusion about whether the existing setup can be adapted for a gauge or if a complete redesign is necessary. Participants clarify that a transducer typically outputs a 4-20 mA signal, which is not directly compatible with a standard pressure gauge. Guidance is sought on how to connect a pressure gauge to the existing setup without starting over.

just some dilemma I ran into

I have an experimental setup with a pressure transducer output connections (wires)...I deemed now that a pressure gauge alone will suffice. How do I connect the wires to a pressure gauge?

Or do I need to re-do everything?

I'm confused on what you are trying to do. The transducer should give you a 4-20ma output to which you can connect to determine the pressure based on the range of the transducer (e.g. 4ma = 0 psig and 20ma = 1000 psig or whatever its max pressure is).

Thanks,

understand your confusion too !

The thing is the setup has outputs for a transducer but does not have a transducer so rather than spending the money to buy a new one I just wanted to connect it to a pressure gauge (cheaper one) as the intent is to only know the pressure and not control it!

I do not know how to change everything and setup afresh for the pressure gauge setup? Could anyone guide me on how I could connect a pressure gauge on a general experimental setup?

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
