CLAIMS

1. An organic liquid sensor configured to output a signal corresponding to the presence of one or more organic liquids and comprising:

a circuit board; and

a sensor film deposited on the circuit board, the sensor film comprising a first length, a second length, and a bridge portion, the first length and the second length being electrically separated by a gap and the bridge portion being electrically coupled to the first length and the second length,

wherein the circuit board is configured to detect a resistance of the sensor film.

2. The sensor of claim 1, wherein the bridge portion is directly coupled to the first length and the second length.

3. The sensor of claim 1, wherein the first length and the second length are physically separated by the gap.

4. The sensor of claim 1, wherein the circuit board comprises a flat surface, and wherein the first length, the second length, and the bridge portion are arranged on the flat surface.

5. The sensor of claim 1 further comprising an electronic monitoring circuit comprising a first terminal and a second terminal, the first terminal electrically coupled to the first length, and the second terminal electrically coupled to the second length.

6. The sensor of claim 5, wherein the first terminal, the first length, the bridge portion, the second length, and the second terminal are electrically coupled in series without any conductive metals exposed to the elements.

7. The sensor of claim 1, wherein the one or more organic liquids comprises at least one of diesel fuel, gasoline, or jet fuel.

8. The sensor of claim 1, wherein the circuit board comprises an electronic monitoring circuit coupled to the sensor film and configured to determine the resistance of the sensor film and output the signal corresponding to the presence of one or more organic liquids based on the resistance of the sensor film.

9. The sensor of claim 8, wherein the resistance of the sensor film increases in the presence of the one or more organic liquids.

10. The sensor of claim 1, wherein the sensor film is deposited on a single side of the circuit board in a U-shape pattern.

11. The sensor of claim 1, wherein the circuit board comprises a treated surface, the sensor further comprising a primer layer deposited on the treated surface, wherein the sensor film layer is deposited on the primer layer.

12. The sensor of claim 1, wherein the sensor film comprises an elastomer filled with conductive particles.

13. The sensor of claim 1, wherein the sensor is configured to couple to a controller and output the signal to the controller.

14. The sensor of claim 1, wherein the gap extends through the circuit board.

15. An organic liquid monitoring system comprising:

a controller comprising a memory and a processor; and

an organic liquid sensor configured to output a signal corresponding to the presence of one or more organic liquids, the organic liquid sensor comprising:

a circuit board configured to detect a resistance of a sensor film deposited on the circuit board, the sensor film comprising a first length, a second length, and a bridge portion, the first length and the second length being electrically separated by a gap and the bridge portion being electrically coupled to the first length and the second length,

wherein the controller is coupled to the organic liquid sensor and configured to receive the signal corresponding to the presence of one or more organic liquids.

16. The system of claim 15, wherein the circuit board comprises a flat surface, and wherein the first length, the second length, and the bridge portion are arranged on the flat surface.

17. The system of claim 15, wherein the sensor further comprises an electronic monitoring circuit comprising a first terminal and a second terminal, the first terminal electrically coupled to the first length, and the second terminal electrically coupled to the second length, wherein the first terminal, the first length, the bridge portion, the second length, and the second terminal are electrically coupled in series without any exposed conductive metals.

f8. An organic liquid sensor configured to output a signal corresponding to the presence of one or more organic liquids and comprising:

a circuit board;

an electronic monitoring circuit comprising a first terminal and a second terminal; and a sensor film deposited on the circuit board, the sensor film comprising a first length, a second length, and a bridge portion, the first terminal electrically coupled to the first length, and the second terminal electrically coupled to the second length, wherein the first terminal, the first length, the bridge portion, the second length, and the second terminal are electrically coupled in series without exposed conductive metals.
