Abstract
A moisture regulating electrochemical sensor includes a sensor electrolyte housed in a chamber of a casing configured with electrodes connected electrically to the sensor electrolyte and configured to be connected electrically to an exterior circuit, an inlet, a vent, and a membrane permeable only to moisture, the chamber between the inlet and the vent each to the sensor electrolyte in the chamber, the inlet allowing a target gas to pass through from an exterior target gas environment to the sensor electrolyte in the chamber, and the membrane operatively coupled to the vent, allowing only moisture to translate through the vent between an exterior vent environment and the sensor electrolyte in the chamber.
Claims27
A moisture regulating electrochemical sensor, comprising:
- a sensor electrolyte carried by an absorbent medium housed in a chamber of a casing configured with electrodes each connected electrically to the sensor electrolyte by a lead extending into the absorbent medium and configured to be connected electrically to an exterior circuit, an inlet, a vent, and a membrane, the chamber between the inlet and the vent;
- the inlet allowing a target gas to pass through to the sensor electrolyte in the chamber from an exterior target gas environment;
- and
- the membrane operatively coupled to the vent and permeable only to moisture to allow only moisture to pass through the vent between an exterior vent environment and the sensor electrolyte in the chamber and stop the target gas from passing through the vent to and contaminating the exterior vent environment from the sensor electrolyte in the chamber.

- and
- an interior filter in the chamber between the inlet and the sensor electrolyte, the interior filter permeable to the target gas and configured to stop solid particulates carried by the target gas from passing through from the inlet to the sensor electrolyte carried by the absorbent medium directly contacting the interior filter.
