Neptune optical sensors
- Thread starter five.five-six
- Start date
I've had both OS and float switches fail. I like the fact that OS have no moving parts and less susceptible to outside factors that might make the float stick. OS are relatively cheap and easy to replace too. I know the early OS1 sensors failed because water of water ingress. Probably due to poor application of the potting compound or using the wrong type. I am also using a MOS with no issues but haven't broken one open to see if the design is better. I might try adding rtv to the seams to make them last longer.
Your MOS failed...damn.... /looks at my MOS
I hope mine last longer since it is really a backup emergency high level sensor, and never see any water near it. But who knows, all I know is the Neptune quality is cheap. Like others, if I wasn't so deep in the APEX ecosystem and have so much invested in it, I would probably be switching.
It really shouldn't be this bad. My Tunze ATO optical sensor has been working flawlessly for 10+ years. And that touches saltwater all the time and all kinds of crude.

Im pretty sure the failure mode is 99% water leaking into the sensor. I'm seriously gonna start adding an extra layer of rtv around all the joints when I have to swap out my sensors. Silicone adhears well and is flexible so should last a lot longer.
FYI, a quick way to tell if your OS is working is to point your phone camera at it. Digital camera sensors are sensitive to the IR spectrum so you'll see it on your phone screen even thought it's invisible to the naked eye.
