Hi All,
Anybody know what’s the mechanical parts that limit the depth rating for both sonar and altimeter?
Hi @SubseaLED,
They both have air-filled electronics enclosures, which I’d guess would be the primary failure point, but I’m not certain. I don’t expect we’ve done detailed analyses of individual parts so much as designed the devices to a minimum requirement, tested them to failure (possibly in various different conditions), then rated them with some safety factor below the lowest failure point.
I will ask internally in case there’s more information available about the testing conditions and/or any straightforward ways of increasing the depth rating, but no guarantees there’ll be an easy answer.
Hi @SubseaLED -
I believe in both cases it is the transducer itself - on the Ping360 the case can compress and prevent the stepper motor from spinning the scanning transducer. In the Ping, the transducer itself can be cracked, as the case is air-filled. We’ll report back if the team shares more information!
Thank you both guys, i wait for further details on the sensors head if both of them could works up to 100bar.
@tony-white I though that at least the ping360 head was oil filled.
Hi @SubseaLED -
The Ping360 head is oil filled - sometimes a small amount of air can be found there that doesn’t normally affect performance.
The bottom of the Ping360 case is the limiting factor - it is air filled and collapses when the depth rating is exceeded.
The Ping transducer was confirmed to crack due to the backing foam flexing, again when the depth rating is exceeded.
Thanks for the info Tony
