Abstract
A system and method for regulating the temperature of a sensor to reduce temperature gradients that form within the sensor. In one embodiment, the temperature gradients are reduced utilizing a temperature regulator with two controlled zones that surround a variable capacitance sensor. Measurements are made for the ambient temperature of at least one of the two temperature controlled zones, and the temperature differential between the two temperature controlled zones. The temperature regulator then adjusts the temperature of the two controlled zones based upon this differential in order to minimize the existing temperature gradient.
