ABSTRACT:
A moisture sensor working to measure a moisture content of a specified measurement gas is provided which consists of an electrochemical cell having a first electrode exposed to the measurement gas and a second electrode exposed to a reference gas and a controller. The electrochemical cell outputs an electrical energy arising from chemical reaction of the measurement gas with the reference gas. The controller controls at least one of voltage appearing across and current flowing through the electrochemical cell and uses one of them to measure the moisture content of the measurement gas. This enables the moisture content to be determined free from the humidify of the measurement gas.
