Temperature and moisture probe

摘要

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.
