Design, development and manufacture of a device to determine the distance between nodes in the standing waves and practical application of this method

The paper studies the standing wave effect, as it is used in various scientific and technology areas. Due to increased popularity of the standing waves and the missing simple solutions in their measurement, the paper proposes a new method for measuring the distance between the nodes and antinodes in the standing waves and demonstrates its practical application. A compact device was designed and developed making it possible to measure the distances between the nodes (antinodes) of the standing waves. The device would be a basis for the structural state sensor of the sound duct generating an alarm signal, if the temperature at any point exceeds the specified value. The device is planned for using as a linear temperature alteration sensor. Unlike the devices available in the market that are bulky and require using additional tools, the device being developed would be compact and affordable. It would be a linear temperature sensor based on the standing wave effect making it possible to measuring the cable temperature at large distances.
