Abstract
The subject transducer consists basically of a flexible element, such as a wire, formed and supported to vibrate at a frequency depending, in part, upon the tension of the element. Means are provided to vary the tension of the element in accordance with a condition which it is proposed to monitor and a fluidic circuit is associated with the element to create a signal in accordance with the vibration of the element, the signal in turn being applied to an electric means to convert the signal into one which can actuate an electrical meter or the like. The device may be modified to include means for initially adjusting the tension of the element to set the system on zero indication and other means for adjusting the tension automatically to compensate for temperature variations.
