Piezo tubes

 

开云体育

Morning all,

I’m on the hunt for some piezo tubes and came across this supplier:


They seem to have a wide range of sizes and thicknesses available and I wondered what the theory is behind the dimensions of the tube for hydrophone purposes.?

Is bigger and thinner always going to be better?

Any insights gratefully received,?

Jack

Morning?Jack. I have found most of them work. Cylindrical ones make great hydrophones. You want some robustness to them as far as thickness. They key is type of material Please see this for more information.?

One of the other things I found is that most vendors assume you are doing something commercial and are set up to be B2B suppliers. They will custom?make almost any size but are interested in large quantity?orders.?

I would?try buying a few and see how they respond to small quantity orders.

Hi Jack,
?
I've had some great results with approx. 25mm diameter, 20mm length and 2-3mm thickness.
I'd be interested to know if you get lucky with PI. Last time I checked with them during the summer, their minimum order was ?1000 before tax and shipping.
They did not have any overstock tubes available, not even a selection of samples. One would have to order something around 100pcs.
When I did order some tubes a few years ago, they were about ?120 each. More expensive than comparable US products, but then, you can't beat Vorsprung durch Technik ;-)
?
Best,
David

 

I had the same experience with them. I ended up ordering some from JLI but spoke to them first and arranged shipping which wasn't the same cost as the actual parts I ordered. I also tried 'Alice' in China, but they worked out even more expensive than buying from the US.
I honestly don't know how companies can actually make anything in the UK any more. We seem to get hammered from all sides now.
I'd be very interested to hear if you do find a decent source though Jack.?
As an aside, I'd also be interested to know who you use for the ENP on your mic housings. It really is a fantastic treatment and I can't believe just how much strength my Type-A has as a result of it.
