ABSTRACT:
A wet bulb sensor system for taking the wet bulb temperature of air. The sensor system includes an air passageway, a fan for drawing the air into and through the passageway, a filter disposed adjacent the intake of the air passageway, a temperature sensor for determining the temperature of air, a wet bulb sump opening upwardly into the passageway, a tank holding a quantity of replenishment water, a wick surrounding the lower end of the temperature sensor and extending into the sump, a water conduit communicating the tank with the sump, and an air conduit communicating the air space above the water in the sump with the space in the tank above the water therein. A second embodiment does not have the air conduit communicating the air space above the sump with the air space in the tank, but instead has a pressure sensor operatively coupled to the tank for increasing the air pressure in the tank to force the water to an operating level in the sump when the fan is operating, and for decreasing the air pressure in the tank to cause the water in the sump to drop below the wick when the fan is not operating. A modified arrangement of the wick is provided wherein the wick extends lengthwise along a sufficient portion of the length of the air passageway to pre-cool the air and water in the wick to the thermodynamic wet bulb temperature of the air flowing through the air passageway.
