Abstract
Disclosed herein are sensors, and method for making an using the same. In one embodiment, the sensor comprises: a first electrode disposed on a ceramic substrate, wherein the first electrode comprises an amorphous metal material comprising a first metal selected from the group consisting of a Group 9 metal, a Group 10 metal, a Group 11 metal, and combinations comprising at least one of the foregoing first metals, and zirconium or at least one of phosphorus and boron.
Claims21
A fuel level sensor, comprising:
- a resistive card having an arc shaped resistive path comprising a first set of spaced apart connector lines and an arc-shaped electrode overlying the first set of conductor lines;
- and
- an arc-shaped conductive path comprising an arc-shaped continuous conductor base and a second set of spaced apart parallel conductor lines extending from the conductor base at an angle with respect to a radial line drawn from a center of the arc-shaped conductor base;
- wherein the electrode comprises an amorphous metal material comprising a first metal selected from the group consisting of a Group 9 metal, a Group 10 metal, a Group 11 metal, and combinations comprising at least one of the foregoing first metals, and zirconium or at least one of phosphorus and boron.
A method for detecting fuel level, comprising:
- contacting a fuel level sensor with a fuel in a fuel storage vessel, wherein the fuel level sensor comprises:
- a resistive card having an arc shaped resistive path comprising a first set of spaced apart connector lines and an arc-shaped electrode overlying the first set of conductor lines;
- and
- an arc-shaped conductive path comprising an arc-shaped continuous conductor base and a second set of spaced apart parallel conductor lines extending from the conductor base at an angle with respect to the radial line drawn from a center of the arc-shaped conductor base;
- wherein the electrode comprises an amorphous metal material comprising a first metal selected from the group consisting of a Group 9 metal, a Group 10 metal, a Group 11 metal, and combinations comprising at least one of the foregoing first metals, and zirconium or at least one of phosphorus and boron;
- and
- determining the resistance between the connector lines and using the resistance to determine the level of the fuel.
