1. A system for detecting the presence of a gas, comprising:

  • a transmitter portion including a transmitter processor;

    a sensor portion including a sensor processor, the sensor portion adapted to sense gas; and

    a variable voltage supply associated with the transmitter portion and the sensor portion, the variable voltage supply including a plurality of potentiometers to enable coarse and fine voltage adjustment;

    the sensor processor configured to communicate a required voltage to the transmitter processor, the transmitter processor configured to set at least one of the plurality of potentiometers to a default value to deliver an operating voltage corresponding to the required voltage to the sensor portion, the sensor processor further configured to measure an actual voltage received from the transmitter processor and to communicate the actual voltage to the transmitter portion, the transmitter processor further configured to compare the actual voltage to the required voltage and to adjust the operating voltage toward the required voltage.
