I have been fishing around for a good sensor for many applications and this may be the one. Affordable, has exposed wire pigtails, and 1/4" thread. Does anyone have the wiring for it or a schematic for a truck or tractor that uses one?

There's something weird Mark. On the LH sidethe Digital Sensor Power is listed as +8V on the RH side the feed into the sensor is marked as +5V. Which one's correct..? Birken, your problem with this sensor is going to be finding a good source of supply of digital voltage. I guess it'll have to come from an ECM somewhere, it can't come from anywhere else.
My question would be is what form does the output signal have, digital on off?
Most of them have some kind of circuit inside, might even be a microprocessor that monitors the capacitance on the probe and grounds the signal wire when the level is low. Some even have a 4th wire that goes high so you can hook it to either kind of circuit. So I don't think +5v or +8v matters too much but maybe +12v might be too much for it, who knows. Thanks for the info, I guess I ought to keep looking though unless we can confirm this one works on 12v also.
hi looking at the circuit operation for a AD45 the sensor supply is stated as 8V also changes number to 430-9449 Mark
I've used these in the past, might be more cumbersome than you're looking for: http://www.ebay.com/itm/R4290-Isspro-Low-Water-Alarm-Kit-New-/262137792002 And 24 volt: http://www.ebay.com/itm/R4290-24VDC-Isspro-Low-Water-Alarm-Kit-New-/262137811797
I would suggest the 4309443 sensor. It works at battery voltage, either 12 or 24v.
Ooh! There ya go!
apologies for the poor quality. Mark
The reason I keep fishing around is I have a number of units I'd like to do but pricing and availability are all over the place. So far I have 5 different part numbers that all do 12vdc ranging from $150 to over $400. So I am trying to find the best one for the application.
