Abstract: An electrochemical gas sensor biasing module may include a main housing, a battery that is contained in and/or extending from the main housing, and a sensor connector extending from a portion of the main housing. The sensor connector is configured to removably connect to an electrochemical gas sensor so that energy from the battery is delivered to the electrochemical gas sensor in order to maintain the electrochemical gas sensor in a biased state.

Abstract: An automatic sensor excitation voltage adjustment feature, a multi-range concentration feature, a single calibration feature and a barrier circuit feature. The automatic sensor excitation voltage adjustment feature includes a transmitter having a transmitter microprocessor that provides an initial voltage to a sensor having a sensor microprocessor. As the voltage changes a correction signal is relayed from the sensor microprocessor to the transmitter microprocessor. The correction signal is used to adjust the voltage applied to the sensor. The multi-range concentration sensor feature includes an amplifier associated with the senior/micro-processor to create gain settings used to optimize sensor resolution by changing a gain value for the sensor. This enables use of a single sensor for a variety of different concentration ranges.
