How Many Types of Tank Sensors?
I owned a new TT that I had to do nothing to the tank sensors, and 2 used Winnebago MHs that I replaced the "sensors" in the black tanks. The "sensors" are just rubber well nuts with the brass threaded insert in it for the #10 screws. Nothing more than the screw grounds the light when the liquid reaches it in the tank. I buy the well nuts and stainless screws from Home Depot.
I do know that some sensors now are of the optical variety, but are there different type of "sensors" installed by other manufacturers?
