Martin and sen2two, From what I read, the sensor measures the capacitance and converts to a voltage. It should be very linear since the capacitance between 2 conductors, is directly proportional to the dielectric permittivity (dielectric constant) of the material between those conductors. IE, as the fuel level increases, so does the capacitance. There is a circuit that converts that capacitance to a
voltage. It also has low and high fuel level adjustments.
It look like the Aircraft Spruce gauges take a voltage signal which this provides. If the "gauge" you wish to use requires a 0-5V voltage signal, then you should be good to go. Most OEM gauges I am familiar with use a variable resistance for the signal. Some use that as part of a internal voltage divider, some use that resistance in a bridge circuit. Those gauges also use sensors with different values of resistance. Worse yet, some have max resistance at low fuel, some have max resistance at full. This makes it impossible to make a blanket statement of what is right without knowing the requirements of the gauge itself.
I mentioned the adapter which is apparently programmable for all of these "resistance" variables and accepting a 0-5V voltage range, just like the Aircraft Spruce sensor.
The AS sensor can be bent and angled so that the entire length can be used without having to cut it to length. Can it be accidentally bent while refuleling? IDK. For ~$80 less than the AS part, that's right only$37 delivered, is the eBay one. It cannot be bent like the AS sensor, but can be cut between 6.6"-10" long. See below.
