    Abstract: A Bourdon tube pressure gauge is mounted for sensing the pressure of a system. The Bourdon tube is connected to at least one optical strain sensor mounted to be strained by movement of the Bourdon tube such that when the Bourdon tube is exposed to the pressure of the system, movement of the tube in response to system pressure causes a strain in the optical sensor. The optical sensor is responsive to the strain and to an input optical signal for providing a strain optical signal which is directly proportional to the pressure. A reference or temperature compensation optical sensor is isolated from the strain associated with the pressure of the system and is responsive to temperature of the system for causing a temperature-induced strain. The reference optical sensor is responsive to the temperature induced strain and the input optical signal for providing a temperature optical signal which is directly proportional to the temperature of the system. The temperature optical signal is provided for temperature compensation of the strain optical signal. The optical sensors include an optical fiber having intrinsic Bragg grating sensors formed in the optical fiber. The optical fiber is attached to a reference point and to the Bourdon tube such that changes in the position of the tube changes the strain on the optical fiber resulting in a wavelength shift of light reflected by the Bragg grating. The magnitude of the wavelength shift is directly proportional to a change in pressure.

    Abstract: A residual pressure sensor for ascertaining a zero residual pressure, and an apparatus for monitoring the sensor for failure thereof. In order to detect a residual pressure reduced to zero, the condition of variation of an output from a residual pressure sensor is detected. This residual pressure sensor is not allowed to generate an output representative of zero residual pressure while the first-mentioned output varies. The energizing condition of a driving solenoid (21) for a solenoid valve which is adapted to open and close a pressure supply passage is monitored by using a current sensor (21) of a fail-safe structure adapted to detect the presence of a current and output a logical value 0, and detect the absence of a current and output a logical value 1, and the residual sensor is monitored for failure based on the monitor output condition of the current sensor and the output condition of the residual pressure sensor.

    Abstract: A system and method are provided for determining wall thickness of a structure such as a metallic pressurized pipe. The system includes an optical fiber having a plurality of Fiber Bragg Gratings (FBGs), and a mounting for securing the FBGs over discrete portions of the exterior surface of the pipe such that strain in the pressurized pipe wall is transmitted to the FBGs. The system further includes a light source and a light sensor coupled to an end of the optical fiber. The light sensor converts light reflected back from the FBGs into electrical signals that a digital processor converts into strain measurements. The FBGs are mounted around portions of the pipe expected to have significant metal loss as well as portions of the pipe expected to have negligible metal loss. The method includes at least one of comparing relative strains at locations with negligible metal loss to those with significant metal loss to accurately determine the thickness of the wall with metal loss; compensating for temperature effects by considering relative strains at areas of the pipe with and without metal loss; and measuring axial strain on the pipe with one or more of the FBGs to correct for at least one of bending and torsion effects on hoop strain.
