Abstract
A probe for measuring the temperature and moisture of a gas has an aspirated flow passage with a configuration that causes the gas to have turbulent flow and, therefore, to mix. A dry bulb thermometer and a wet bulb thermometer positioned in the flow passage downstream of the configuration that causes mixing measures the temperature and moisture of the gas. A wick and a water reservoir for keeping the wet bulb thermometer wet are cleaned and refilled by a flow of water through the gas passage. The gas passage is heated to prevent condensation of any moisture in the gas.
Claims20
A probe for measuring the temperature and moisture of a gas, comprising:
- an aspirated flow passage for the gas, said flow passage having a configuration that causes the gas to have turbulent flow;
- a dry bulb thermometer positioned in the flow passage downstream of said configuration;
- and
- a wet bulb thermometer positioned in the flow passage downstream of said configuration,
- whereby the gas is mixed by the time the gas reaches the thermometers.
A method for measuring the temperature and moisture of a gas, comprising:
- aspirating a flow of the gas through a flow passage having a configuration that causes the gas to have turbulent flow, whereby the gas is mixed;
- measuring the temperature of the mixed gas with a dry bulb thermometer downstream of said configuration;
- and
- measuring the temperature of the mixed gas with a wet bulb thermometer downstream of said configuration.
