leak detection

[Maximus Rumpas]

Hi All,

A few forum members have mentioned using a leak detection system within the pressure chamber. How is this done? Possibly by monitoring the internal pressure and humidity???

The leak detectors I've seen (and something I plan on using) is a pcb with copper etches on it. You can sort of make it out in this pic:

look on page 8 and 9 to see the leak detectors for this rov control system. they use the same concept.

Forget the upper part ( the power supply ) and use the ROV power instead.
Place electronics in controller and place a sensor in the ROV

sensor can be 2 wires with ~ 1cm blank ends use some HMA (Hot melt adhesive) to secure on the ROV bottom

Thanks to both of you,

I took a look at the detector recommended by Derelicte and sold by FloodStop, they sell additional/replacement units for $13.00.

Found this and i guess it would be the easiest and most straight forward way to do a leak detector. Instead of a buzzer... have it as an input to the control system? How would one do that? Well let me just show you the video:

to replace the buzzer I would recommend the use of a microcontroller, such as an arduino. See how many volts are coming from the positive wire that would normally go to the buzzer. If its less than like 5 volts you should be fine. If its more get a 5v regulator. Share the negative (ground) with the arduino. Done
