Title: APPARATUS AND METHODS FOR MEASUREMENT OF PRESSURE
Abstract:
A strapping device for a pipe and methods of using the strapping device to non-invasively detect pressure inside the pipe and the residual stress exerted on the pipe. The strapping device includes a linked or a solid band adapted to be fitted around an outside diameter of the pipe. The strapping device further includes a sensor for measuring at least one of a change in the outside diameter of the pipe due to a corresponding change in pressure inside the pipe and to detect the stress or strain transferred from the pipe. The measurements can be conveniently processed in a circuit board coupled to the strapping device or in a remote location. The measurements can be transmitted through wires or digitally transmitted to the circuit board.
