Development of a Distributed Crack Sensor Using Coaxial Cable

Cracks, the important factor of structure failure, reflect structural damage directly. Thus, it is significant to realize distributed, real-time crack monitoring. To overcome the shortages of traditional crack detectors, such as the inconvenience of installation, vulnerability, and low measurement range, etc., an improved topology-based cable sensor with a shallow helical groove on the outside ...

A new position detection method using leaky coaxial cable

Recently, the demand on position detection system using WiFi[1] and cellular phone[2] have been appeared. Car navigation system and 3G cellular phone use GPS(Global Positioning System) for position detection. However, it is impossible to use GPS underground because GPS signal cannot be received due to obstacles. Therefore, many position detection methods to use at narrow area have been proposed...

Design and Implementation of an Intrinsically Safe Liquid-Level Sensor Using Coaxial Cable

Real-time detection of liquid level in complex environments has always been a knotty issue. In this paper, an intrinsically safe liquid-level sensor system for flammable and explosive environments is designed and implemented. The poly vinyl chloride (PVC) coaxial cable is chosen as the sensing element and the measuring mechanism is analyzed. Then, the capacitance-to-voltage conversion circuit i...

An Off-Center “Coaxial” Cable

A “coaxial” transmission line has inner conductor of radius a and outer conductor of radius b, but the axes of these two cylinders are offset by a small distance δ ¿ b. Deduce the capacitance and inductance per unit length, and the impedance Z, accurate to order δ/b. The (relative) dielectric constant and permeability of the medium between the two conductors both unity. The relevant frequencies...

“Hidden” Momentum in a Coaxial Cable

Calculate the electromagnetic momentum and identify the “hidden” mechanical momentum in a coaxial cable of length L, inner radius a, outer radius b, when a battery of voltage V is connected to one end and a load resistor R0 is connected to the other. The current may be taken as uniformly distributed over the inner conductor, which has resistivity ρ. The outer conductor has negligible resistivit...
