Abstract

Intrinsically safe and explosion proof enclosure platforms for convertible gas detectors are disclosed. In some embodiments, a convertible gas detector comprises a gas sensor, the gas sensor comprising sensor circuit. The gas detector further comprises an enclosure, the enclosure configured to house the sensor circuit. The gas sensor further comprises an end cap, the end cap configured to be detachably connected to the enclosure along a flamepath joint. The gas detector is configured to switch between operating as an explosion proof detector and an intrinsically safe detector responsive to whether the end cap is connected to the enclosure.

Claims (37)

1 . A convertible gas detector comprising:

a gas sensor, the gas sensor comprising a sensor circuit;

an enclosure, the enclosure configured to house the sensor circuit; and

an end cap, the end cap configured to be detachably connected to the enclosure along a flamepath joint, wherein

the gas detector is configured to operate as an explosion proof detector when the end cap is connected to the enclosure, and is configured to operate as an intrinsically safe detector when the end cap is not connected to the enclosure.

2 . The convertible gas detector of claim 1 , wherein responsive to connecting the end cap to the enclosure, the gas detector operates as an explosion-proof detector.

3 . The convertible gas detector of claim 1 , wherein responsive to removing the end cap from the enclosure, the gas detector operates as an intrinsically safe gas detector.

4 . The convertible gas detector of claim 1 , wherein

the enclosure comprises a bottom end;

the end cap comprises a base element; and

the end cap is configured to be detachably connected to the enclosure such that the base element interfaces with the bottom end with of the enclosure to form a flameproof joint.

5 . The convertible gas detector of claim 1 , wherein

the enclosure comprises a side wall, the side wall having an inner wall and an outer wall;

the end cap comprises a projecting element; and

the end cap is configured to be detachably connected to the enclosure such that the projecting element interfaces with a portion of the outer wall to form a flameproof joint.

6 . The convertible gas detector of claim 1 , wherein

the enclosure comprises a side wall, the side wall having an inner wall and an outer wall;

the end cap comprises a projecting element; and

the end cap is configured to be detachably connected to the enclosure such that the projecting element interfaces with a portion of the inner wall to form a flameproof joint.

7 . A method of manufacturing a convertible gas detector, the method comprising:

providing a gas sensor, the gas sensor comprising a sensor circuit;

providing an enclosure, the enclosure configured to house the sensor circuit; and

providing an end cap, the end cap configured to be detachably connected to the enclosure along a flamepath joint,

wherein the gas detector is configured to operate as an explosion proof detector when the end cap is connected to the enclosure, and is configured to operate as an intrinsically safe detector when the end cap is not connected to the enclosure.

8 . The method of claim 7 , wherein responsive to connecting the end cap to the enclosure, the convertible gas detector operates as an explosion-proof detector.

9 . The method of claim 7 , wherein the sensor circuit is intrinsically safe; and

responsive to removing the end cap from the enclosure, the gas detector operates as an intrinsically safe gas detector.

10 . The method of claim 7 , wherein

the enclosure comprises a bottom end;

the end cap comprises a base element; and

the end cap is configured to be detachably connected to the enclosure such that the base element interfaces with the bottom end with of the enclosure to form a flameproof joint.

11 . The method of claim 7 , the enclosure comprises a side wall, the side wall having an inner wall and an outer wall;

the end cap comprises a projecting element; and

the end cap is configured to be detachably connected to the enclosure such that the projecting element interfaces with a portion of the outer wall to form a flameproof joint.

12 . The method of claim 7 , the enclosure comprises a side wall, the side wall having an inner wall and an outer wall;

the end cap comprises a projecting element; and

the end cap is configured to be detachably connected to the enclosure such that the projecting element interfaces with a portion of the inner wall to form a flameproof joint.
