Discussion Overview

The discussion revolves around conducting pressure decay testing, specifically focusing on the setup required for a 10-minute decay test and the electronic transmission of results to a storage location. The scope includes practical advice on equipment and methods for data logging and measurement.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks advice on conducting a pressure decay test and transmitting results electronically.
  • Another participant asks about the user's experience with measurement methods and equipment, inquiring about the specifics of the pressure measuring equipment and its communication capabilities.
  • A participant suggests starting from scratch and requests guidance on constructing a simple yet effective setup for the desired testing outcome.
  • One reply expresses confusion over the initial request, asking for clarification on the exact goals of the testing.
  • Another participant proposes using a Programmable Logic Controller (PLC) for the testing setup, mentioning various input interfaces and the need for clarity on logging methods.
  • The discussion includes a metaphorical example of using basic tools to illustrate the range of possible solutions, emphasizing the need for more defined requirements to provide targeted advice.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are multiple competing views on how to approach the pressure decay testing setup, and the initial request lacks sufficient detail for targeted advice.

Contextual Notes

Limitations include the lack of specific information about the user's existing equipment, the desired method of data logging, and the overall constraints of the testing setup.

Who May Find This Useful

Individuals interested in pressure testing methodologies, data logging techniques, and those seeking practical advice on setting up experimental equipment in a technical context.

TL;DR
Transference of information electronically to alleviate human error
I want to conduct pressure decay testing that will conduct a decay test lasting 10 mins and once the test has concluded transmit test result electronically to a saved storage location. Any advice?

Welcome to PF.

There are lots of ways to measure and log data. Do you have experience with any such methods and equipment?

Can you link to the datasheet for your pressure measuring equipment? Does it already have some electronic communication port for communicating with it? (USB, Ethernet, Serial/RS-232, etc.)

What kind of PC do you have to read and log the data? What communication ports does it have available?

The more you tell us about your setup, the more we can help you get this up and running soon. :smile:
 
The entire idea is at ground level right now. Assume I have absolutely nothing to start with. What advice would you give to construct a simple, but effective means by which to obtain the desired result?
 
To be honest, your response makes no sense. What *exactly* are you trying to do?

In keeping with the "Limited Information Transfer" in this thread, I suggest a Programmable Logic Controller, or PLC as they are often called.

The three major manufacturers are: Allen-Bradley, Texas Instrument, Siemens. Input interfaces available include: On-Off Voltage (AC & DC, Analog Voltage (AC & DC), 4-20mA Current; along with a multitude of sensors from various manufacturers.

You mention Logging. Does this mean to a printer, graphic display, mass storage device (what kind? hard disc drive, Solid State Drive, other?)

So far you are asking on the order of "I want to make marks on paper." That could be a $4000 high speed line printer down to grab a piece of charcoal and draw a line.

For instance you could use a bellows, a pencil, and have the pencil poke a hole in the paper when the pressure gets too low. That meets your stated constraints.

So far, we have no idea what you think you need or how it is to be presented as useful information.

If you want targeted answers, further define the problem and your constraints.

Cheers,
Tom
