Abstract
A draft sensor includes a frame with an opening between a pair of spaced-apart portions which have a variable separation depending upon the force applied to the ends of the frame. Recesses or bores in the spaced-apart portions receive projections which project from the cap and base which form opposite ends of a transducer which contains a linear variable differential transformer. The transducer is spring-loaded to facilitate assembly or replacement of the transducer in the frame.
