Turbidity Sensor testing water in a tank
CLAUDIO.WICHER 2025-09-28 00:29:42 245 Views2 Replies Hello, I'm working on a design to monitor water turbidity in a 500-liter residential tank. I've read that the top of the sensor isn't waterproof. Since the water level inside the tank varies considerably, I'd like to know the recommended installation method for this sensor. Can this top part be covered with epoxy resin? Or is there another solution? Thank you in advance.
If you can, mount the sensor so the top stays above the maximum waterline (electronics dry) and put only the sensing tip in the water. That’s simplest and safest.
If the entire sensor must be submerged, use a sealed waterproof probe or an external housing with an optical window and sealed, potted electronics.
ahsrab.rifat Thank you for your idea! The 2nd option will be better, because the liquid level isn´t constant and the first may be a risk for the electronics.
I´ll try using a transparent sealed tube with the sensor inside. It´s a good idea!
