ABSTRACT:
Sensors, apparatus and methods are disclosed for detecting airflow direction between two volumes. The preferred airflow sensor includes a tube for conducting an airflow stream between the volumes, a first temperature sensor sensing ambient temperature in the first volume and a second temperature sensor sensing temperature of the airflow stream in the tube. A heat source heats air in the tube adjacent the end thereof communicating with the second volume and a comparator receives and compares output signals from the temperature sensors, providing an output indicative thereof. Various means are provided responsive to the output advancing appropriate response thereto. The disclosed sensors, apparatus and methods are particularly well adapted for indicating positive and negative pressure differentials at flues associated with combustion appliances.
