Hi
Im looking at buying a pressure transducer e.g. Pico WPS, can someone tell me if there is a better product on the market or is this one the best ??? I will be using it for running comp tests and maybe fuel pressure and so on, I already have a FLS but I know I can't use this tool for everything I want....

Thanks in advance
Ron

Ron,

the WPS is the cat's meow  :D
Look at any other transducer capture along side the Pico and you'll see.

WPS is best by far, but the Fluke PV350 is nothing to sneeze at if you know a few tricks to enhance its performance

I'm glad I went straight for the WPS, it's awesome.  I'm amazed almost every time I use it how accurate it is.  Get the whole kit and you will not be disapointed.

Hi

Thanks for the advice guy's, I had already decided on the WPS really but just thought I'd ask the experts first......
I will let you know when I get it and post some waveforms up so I can get some advice for a beginner........


Thanks
Ron

What are the special tricks for the Fluke? I have one but wish I had the money for the Pico

I would like to know to? What the special tricks for the Fluke are?
The only thing I can think of is using the KPA scale gives better resolution compared to the PSI. and use the picoscope software filters after you have recorded, to clean up the signal a bit if needed.
The fluke works pretty good, but I would like try the pico transducer, I just wish the vacuum sensor on pico could be used the same time as the higher pressure side.

I have a versus scanner from snapon and I'll like to buy a wps 5000 and I'll like to know if anybody knows how it works on the versus thanks in advance

It does.  You just have to adapt the BNC cable to the banana sockets on the Verus (we stock the adapters).  You will not be able to scale in pressure units is all.  That just means you'll have to do the math to convert the voltage to pressure for the scale you are using.

Here is an image of the WPS being used on a heritage Vantage:

We're looking at different transducers at the moment but need a larger range than the Pico WPS500X:
Range      Pressure range      Accuracy      Response time      Output scaling
1      -15 to 500 psi
-1 to 34.47 bar      1% of scale      100 µs      10 mV/1 psi
(500 psi = 5 V)
2      -15 to 50 psi
-1 to 3.45 bar      1% of scale      100 µs      100 mV/1 psi
(50 psi = 5 V)
3      -5 to 5 psi
-0.34 to 0.34 bar      5% of scale      filtered      1 V/1 psi
(5 psi = 5 V)


We have the First Look unit, but can't find anywhere the tech spec on that unit, even Pico, AutoNerdz or Senxtech who make them, all fail to give any tech info!

Fluke are one of the few others to do an automotive unit with their PV350, but it is effectively the same overall scale although the accuracy and ranges might be different, and from the comments here, it seems the PICO is massively superior ... is that both resolution and noise reduction?

thanks

What range did you need, Richard?

There are only three transducers out there that I am aware of that produce accurate results under dynamic conditions such as in cylinder pressure testing.  The WPS, the Fluke PV350, and the DCTI.  All others skew results under these conditions.

The WPS has superior sensitivity and versatility.

The FirstLook does not measure pressure and has no specs.  The voltage change is relative to the amount of pressure change and the rate of change.  Any steady state is a zero output.  It only measures changes.  It's a pulse sensor not a pressure transducer.

First Look ... ok, that answers that then.

Range.
We are looking to map things like the F1 clutch, to look at the relationship between clutch plate position and pressure ... the system works in the 40-60 bar range. There are a few other high pressure range applications, but 60 bar is about max, though 100 bar max might give some future leeway as car makers increase pressures!

I think we'll be adding a Pico WPS500X in the New Year in any event.

Whats the DCTI?
thanks
Richard

We don't carry them anymore because the WPS took over that market for us but they are still available here:

rumor has it that pico is testing a higher pressure transducer  ;).

  I saw that too, I think in the newsletter.  They mentioned something about it being used for high pressure hydraulic applications I think.  Check the Pico website.

I have and use the WPS500x as my primary transducer when doing running / cranking / relative compression testing.  It's performance is fantastic.
I also have the Fluke PV350 and would love to know the "performance enhancing tricks" you have, Randy.
Can you show how you make the waveforms appear cleaner without excessive filtering, please? 
Thank you,
