First Claim
Patent Images
1. A maintenance sensing system for an enclosure, the maintenance sensing system comprising:
- a filter system located in an aperture of the enclosure and configured to control air flowing into the enclosure, wherein the enclosure is suitable for potentially explosive environments;
a sensor configured to measure an operating value of an operating parameter inside the enclosure, wherein the operating value is associated with the air flowing into the enclosure through the filter system;
a control device operatively coupled to the sensor and configured to;
receive the operating value from the sensor;
determine that the operating value exceeds a threshold value; and
perform, based on determining that the operating value exceeds a threshold value, a maintenance operation to reduce the operating value of the operating parameter inside the enclosure.

Abstract
A filter system for an explosion-proof enclosure is described herein. The filter system can include a pre-filter assembly located outside the explosion-proof enclosure. The pre-filter assembly can include a pre-filter material configured to control air passing therethrough. The filter system can also include a filter assembly coupled to the pre-filter assembly. The filter assembly can further control the air received from the pre-filter assembly and passing therethrough into the explosion-proof enclosure.

11. A method for sensing when maintenance for an enclosure is required, the method comprising:
-
receiving, from a sensor, an operating value of an operating parameter inside the enclosure, wherein the operating value is associated with air flowing through a filter system into the enclosure, wherein the enclosure is suitable for potentially explosive environments; determining that the operating value exceeds a threshold value; and performing, based on determining that the operating value exceeds the threshold value, a maintenance operation to reduce the operating value of the operating parameter. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
