Abstract

A temperature monitoring system includes an enclosure, an external temperature sensor, and an internal temperature sensor. The enclosure may be explosion-proof, and may include a controller and an internal display disposed within the enclosure. The external temperature sensor may be configured to detect an outside temperature, and the internal temperature sensor may be configured to detect a temperature inside the enclosure. Upon the external temperature sensor and/or the internal temperature sensor detecting a temperature that meets or exceeds a set or specified value or limit, the system may be configured to implement an action or order. In an embodiment of the system, the system may be configured to stop fueling in the event that the external temperature sensor and/or the interior temperature sensor detect a temperature that meets or exceeds a certain temperature.

First claim

What is claimed is:

1. A temperature monitoring system, comprising:
an enclosure;
a controller and an internal display disposed within the enclosure;
an external temperature sensor configured to detect an outside temperature outside of the enclosure and communicate the outside temperature to the controller; and
an internal temperature sensor configured to detect an inside temperature inside the enclosure;
wherein, upon the controller detecting a change in the outside temperature that exceeds a set value or specified range, the controller implements an action or order to stop fueling.

2. The temperature monitoring system of claim 1 , wherein the enclosure is explosion-proof.

3. The temperature monitoring system of claim 1 , wherein the internal temperature sensor is disposed proximate a location or area of the enclosure expected to have a greatest temperature.

4. The temperature monitoring system of claim 1 , wherein the enclosure includes a cover, the cover includes an explosion-proof window, and the internal display is mounted to the cover and aligned with the explosion-proof window.

5. The temperature monitoring system of claim 1 , wherein the controller includes a first controller, a second controller, and a third controller.

6. The temperature monitoring system of claim 5 , wherein the first controller is mounted to a first wall of the enclosure, the second controller is mounted to a second wall of the enclosure, and the third controller is mounted to a third wall of the enclosure.

7. An explosion-proof enclosure assembly, comprising:
an enclosure, including:
a body; and
a cover;

a display disposed in the enclosure and connected to the cover;
a first controller disposed in the enclosure and connected to the display;
a second controller disposed in the enclosure; and
an external temperature sensor;
wherein, upon the-external temperature sensor detecting an outside temperature exceeds a set or specified value or limit, the first controller implements an action or order, and wherein the first controller is a programmable logic controller, and the second controller is a pressure control module.

8. The explosion-proof enclosure assembly of claim 7 , including:
a terminal block disposed in the enclosure;
a terminator disposed in the enclosure; and
a first wiring harness connecting the first controller with the terminal block and the terminator;
a third controller disposed in the enclosure;
a second wiring harness connecting the second controller with the terminal block and the terminator;
a third wiring harness connecting the third controller with the terminal block and the terminator; and
a fourth wiring harness connecting the display to the terminal block and the terminator.

9. The explosion-proof enclosure assembly of claim 8 , wherein the body includes a first wall, a second wall, a third wall, a fourth wall, and a fifth wall, and the fifth wall is disposed substantially perpendicularly to the first wall, the second wall, the third wall, and the fourth wall.

10. The explosion-proof enclosure assembly of claim 9 , wherein the first controller is mounted to the first wall, the second controller is mounted to the second wall, and the third controller is mounted to the third wall.

11. The explosion-proof enclosure assembly of claim 10 , wherein the fourth wall includes a plurality of apertures and a plurality of certified cable glands connected to at least some apertures of the plurality of apertures.

12. The explosion-proof enclosure assembly of claim 8 , wherein the first controller includes a programmable logic controller, the second controller includes a first fluid pressure controller, and the third controller includes a second fluid pressure controller.

13. The explosion-proof enclosure assembly of claim 8 , including a base plate connected to the body; wherein the terminal block is connected to the base plate via a DIN rail.

14. The explosion-proof enclosure assembly of claim 8 , wherein the terminal block includes a first section, a second section, and a third section, and the first section, the second section, and the third section are separate from each other and disposed substantially in parallel with each other.

15. The explosion-proof enclosure assembly of claim 14 , wherein the first wiring harness is connected to the first section, the second section, and the third section; the second wiring harness is connected to the first section and the second section; the third wiring harness is connected to the first section and the third section; and the fourth wiring harness is connected to the third section.

16. The explosion-proof enclosure assembly of claim 15 , wherein the first section is connected to a fuse to limit an electrical current provided to the first controller, the second controller, the third controller, and the display.

17. The explosion-proof enclosure assembly of claim 7 , wherein the display is mounted to an inner surface of the cover via a bracket.

18. The explosion-proof enclosure assembly of claim 17 , wherein the cover includes a window that is at least semi-transparent and the display is aligned at least partially with the window.

19. The explosion-proof enclosure assembly of claim 8 , wherein the third controller is a pressure control module.
