Title: PQ334 vs WPS500
Post by Stafo on Dec 2^nd, 2023 at 6:58am

Hello, is it worth buying the PQ334 pressure transducer as a second tool to my WPS500?
Will I get similar captures from both tools, if measuring from the same source?

What I want to know is, has anyone compare these two transducers?

I like the idea of not having to recharge the battery, but want to be sure that I can use them together and don't have to worry about different results.

I did read that but doesn't give me confidence in purchasing this transducer. I was hoping someone else had used it.
I will hold off buying this for now.

See the pdf shared by larkin in the thread linked by Trevor. The pdf suggests the PQ334 has a reponse rate of 1ms. As compared to the WPS500X that has a 100us response rate in range 1 and 2. Tom Roberts has demonstrated the response rate as closer to 80us on the WPS500X.

Since larkin owns a PQ334 and a WPS500X, you should contact him directly through his forum user profile with an email. He may have done more testing with the PQ334 since that thread was active.
