New Ping?

Little more than a year ago I was told by Parallax that a redesign of the Ping ultrasonic sensor was in the works. Can we get an update regarding Parallax intentions to offer a redesigned Ping? Thanks.

The Ping))) Ultrasonic Distance Sensor actually was recently revised to Rev B. In this revision, we modified the design to use an external clock signal. However, this doesn't have any effect on the performance of the Ping))) and should have the same functionality as Rev A.

...Even though I do like Matt Smith.
About a year ago the data sheet for this sensor was revised to exclude the application of it looking down a 2 inch PVC pipe. That didn't work. There was some talk that the new sensor would correct this problem. In addition to resolving the release question, has testing been done re the new sensor's ability to measure distance inside a cylinder as it was originally shown?
The revision that I mentioned was for the current Ping))) that we are selling. This was totally minor and does not effect the functionality of the sensor in any way.
Now regarding the PVC application. I believe you're referring to the application that used a PVC pipe to measure water level? That application still is not recommended for the current Ping))) or for the Long Range Ping))) we are currently developing since the transducers used are not water resistant.
The sensor that I think you are referring to is the H2O resistant Ping))) sensor. That sensor, as Dave mentioned, was being developed but is now currently on hold.
Hope that help clears things up (I know, that's a-lotta Pings!), let me know if you have any other questions!
And not a single Pong...
Sorry!

Jessica, FYI... Although it was my intention to use the Ping to measure water depth inside a PVC pipe as the application was originally proposed, the fact that the sensor was not water resistant was not the reason the application was deleted. The application was deleted because it was demonstrated that the sensor failed to function properly (in the absence of water) when it was mounted in a surround cylinder. Testing showed that the surround could not extend more than about 3/16 inch forward of the leading edge of the transmitter/receiver before measurement errors began to occur.
