Abstract

A frequency-sensitive reed will vibrate only when excited by its natural frequency. The frequency of vibration is dependent on the medium surrounding the reed.

Resonant Frequency Reed Relay Low Fluid Level Sensor

A frequency-sensitive reed will vibrate only when excited by its natural frequency. The frequency of vibration is dependent on the medium surrounding the reed.

A fluid will damp the vibration of a reed, tuned in air, to a point where contacts 1 remain open. As the fluid recedes, vibrations of the reed increases to a point where contacts 1 are closed. The closing of contacts 1 is indicative of a low-fluid level.
