Connect pressure transducer o/p to gauge?

Click For Summary
SUMMARY

This discussion centers on connecting a pressure transducer output to a pressure gauge in an experimental setup. The user initially intended to utilize a pressure transducer with a 4-20 mA output, where 4 mA corresponds to 0 psig and 20 mA corresponds to the maximum pressure. However, the user decided to simplify the setup by opting for a pressure gauge instead of purchasing a transducer. Guidance is sought on how to connect the pressure gauge without redoing the entire setup.

PREREQUISITES
  • Understanding of 4-20 mA current loop systems
  • Familiarity with pressure measurement concepts
  • Basic knowledge of electrical wiring and connections
  • Experience with experimental setup configurations
NEXT STEPS
  • Research how to connect a pressure gauge to a 4-20 mA output system
  • Learn about pressure gauge types and their specifications
  • Explore wiring diagrams for integrating pressure gauges into existing setups
  • Investigate cost-effective alternatives to pressure transducers for basic pressure measurement
USEFUL FOR

This discussion is beneficial for experimental engineers, technicians involved in pressure measurement, and anyone looking to simplify their pressure monitoring systems without extensive reconfiguration.

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?
