Fresh Water Tank Sensors

Yahoo Message Number: 73631
Does anyone know the manufacturer of the capacitive-type fresh water tank sensors CC used on the later coaches? Physically, they are just a 1-1/2" x 1-1/2" x 1/8" black plastic-looking square fixed to the water tank by an adhesive. Two wires come from each of the four.
Since we went to a ROM water system, the sensors fail to read at 50%, 75% and 100%. Without having tried the "old tap water" to verify, I wonder if the super-clear ROM water fails to have enough particulates in it to trigger the sensors........???

I'd like to talk to the manufacturer.

Roger,

I think this is what you are look for.

These sensors on "rv gauge" look pretty neat, but don't think it's this type. All models from this company talk about a single sensor for different height tanks. Our tank has four sensors located at 25%, 50%, 75% and 100% levels. And, they are definitely thicker than 0.008".

Roger:

The sensors that are on your tanks are manufactured by SilverLeaf.

To Kevin Waite and others:

The water tank sensors on our coach were made by Touch Sensor (.com).
One cannot put just anything next to them to verify correct operation, it must be a conductive material........like your hand (fingers). So just put your grubby little fingers on top of a sensor and your assistant should see a change in LED operation on the Silver Leaf panel.
Each sensor puts out a very, very small additional voltage when it "sees" the liquid level. This extra voltage is monitored on the Silver Leaf as a change from it's programmed (0) point, so it alerts by lighting an LED. Since each sensor is the same as any of its mates, the addition of this small voltage from multiple sensors "seeing" the liquid is additional and causes a different LED to light on the panel.
The sensors on the fresh tank, gray tank and black tank are all the same. All the sensors' wire leads go to an interface board (maybe located in the water bay some place, but who knows for sure), and then an ethernet-type cable carries the data from the interface board to the Silver Leaf panel.
So, one can interchange wires at the interface board to check the operation of a suspect sensor, by monitoring the Silver Leaf panel.
It takes very little conductive material to trigger a sensor, so if you are consistently getting 1/4 tank when you drain your black or gray, it's most likely because the bottom of the respective tank is just not clean.

That's all I know...............so far.
