A 20kg bar load cell, perfect for weighing heavy objects!
Read moreHi,
I’m interested in your 20kg load cells. I am just wondering how waterproof these load cells are?
I am planning to use these in an application where they will vary between being above water, to being below ~0.8m of water (most of the time will be spent above water, and the water is clean tap water).
Apart from the aluminium corroding, would you expect the sensing elements to cope with being submerged? Alternatively could I epoxy this connection to waterproof it without impacting the accuracy? The actual microcontroller and amplifier will obviously be further away in a dry location.
This would just be used on a test rig that will run for a few weeks, so it doesn’t have to work for years.
Thanks for your time.
Regards,
Jacob

Hey Jacob, Welcome to the forums!
The load cell circuitry is not designed with water contact in mind. It seems like the sensitive parts of the product are protected from the elements with the white coating you can make out in the product photos which may do something to prevent water getting in but you may need to do some testing to find out how effective this is at preventing water ingress.
Waterproof load cells do exist that would probably be a better match for this project although I understand the inclination to go for a standard one. That waterproofing does not come cheap.
It may be a good idea to perform some tests on one of these beam load cells to see what the failure conditions look like when it is exposed to water and if you decide to use it in your project, have a few backups on hand in the case of failure.
Good luck with your testing!
