Techniques for implementing and operating a system that includes a pipe segment, which has tubing that defines a bore and a fluid conduit implemented in an annulus of the tubing, and a test head. The test head includes a shell, which defines an annulus cavity, and an inflatable bladder implemented in the annulus cavity, in which the system maintains the inflatable securing bladder in a less inflated state while pipe segment tubing is not present in the annulus cavity and increases inflation of the inflatable bladder to a more inflated state when the tubing is present in the annulus cavity to facilitate securing and sealing an open end of the pipe segment in the test head to enable integrity of the tubing to be tested at least in part by flowing a test fluid into the annulus of the tubing via a testing port on the shell.

A testbench system is disclosed. The system includes a network interface; a memory storage; a transducer; and one or more processors. The one or more processors are configured to operate in a first phase and: perform calibration of the transducer and generate calibration data; generate a unique identification (CTS-ID) for the transducer based on the calibration data; mark the transducer with the CTS-ID; and provide the CTS-ID and the calibration data to the network interface for transmission to a database

The invention relates to an installation (1) for detecting and locating a leak in at least one fluid transport circuit (Ps, Pt), notably an anemometer circuit of an aircraft, having a leak test apparatus (10) including means (12) for detecting a leak in the said at least one fluid transport circuit (Ps, Pt). In one example, the means for locating a leak includes injecting means (Pp, 14, Ev2) of a trace gas under pressure into the said at least one fluid transport circuit (Ps, Pt), which means are situated in the said leak test apparatus (10), and a trace-gas detection probe (30) intended to be moved along the said at least one fluid transport circuit (Ps, Pt) on the outside thereof, in order to locate the leak.

A tube leak detection device for detecting leak of at least one tube of a heat exchanger which increases a temperature of a liquid by heat exchange between the liquid flowing inside the at least one tube and a fluid flowing outside the at least one tube includes: an inlet opening-and-closing valve and an outlet opening-and-closing valve disposed at an inlet end and an outlet end of the at least one tube, respectively; and a pressure detection member for detecting a pressure inside the at least one tube between the inlet opening-and-closing valve and the outlet opening-and-closing valve.

Semi-automated testing devices for a plumbing stack are disclosed. A semi-automated testing device in accordance with the present disclosure may comprise a transfer pump configured to automatically fill the plumbing stack; at least one automated gripping element configured to grip a supplemental pipe coupled to a pipe of the plumbing stack via a connection; at least one automated sealing element configured to seal the connection; and at least one sensor configured to measure a water level of the supplemental piping. A method of testing the plumbing stack with the semi-automated testing device is also disclosed.

A sensing system (10) for monitoring the integrity of a structure has first and second channels (12 and 14) arranged for sealing onto a surface (16) of the structure (18) to form respective spaced apart first and second galleries (20 and 22). A fluid (F1) is in the first gallery (20) and a fluid (F2) is in the second gallery (22). A measurement system (24) measures for a change in a pressure independent physical characteristic: a) in the first gallery (20); b) in the second gallery (22); c) between the first gallery (20) and the second gallery (22); or d) a combination of two or more of a), b) and c) where the change is dependent on a mass flow of fluid from one of, or between, the sealed galleries due to a crack in the structure. The pressure independent physical characteristic of the fluid can be the conductivity of the fluid or the optical properties of the fluid.

A leakage detection device for detecting water leakage in a water pipe of a water system after a stop valve of the water system is closed. The leakage detection device may be part of a stop valve, and may include an interior chamber connectable to the water pipe in such a way so as to receive a stagnation volume of the water when the water flow through the water pipe is stopped by the stop valve. An actuation element provides a force acting on a diaphragm or a piston in the direction of the first interior chamber and against or into the stagnation volume of water. If water leakage is present in the water pipe, the diaphragm or piston will move under the applied force to compensate for the leakage in the water pipe. A sensor unit may detect water leakage in the water pipe based on the movement.

A method and system of diagnosing the integrity of a sealed air tube of a pedestrian protection system of a vehicle is provided. The method provides the sealed air tube having a pressure sensor connected at each end of the air tube. The air tube is constructed and arranged to be located in front fascia of a vehicle. A processor circuit is electrically connected with the pressure sensors and the processor circuit has a Fast Fourier Transform element. Natural frequencies of a frequency spectrum of the air tube are obtained when no leak is known to be present in in the air tube. Signals from the pressure sensors are transformed into the frequency domain with the Fast Fourier Transform element. A leak is determined to be present in the air tube if frequencies other than the natural frequencies exist in the frequency spectrum of the air tube.
