A gasket with embedded sensors configured for direct measurement of compression. Individual sensors may be mounted on one or more strips of conductive material wherein the strips of material are disposed around the circumference of the gasket. The outer circumferential face of the gasket may feature a groove to accommodate the strips of material having sensors mounted thereon.

A battery pack leakage detection system and detection method are provided. The system includes a test container, a gas filling subsystem, a gas stirring subsystem and a test analysis subsystem. The method can test the sealing performance of the battery pack under the atmospheric pressure, so that the battery pack can meet the corresponding sealing grade requirements of IP67 and IP68. The method not only solves the problem that the traditional gas detection method cannot meet the test requirements of IP67 and IP68 due to insufficient measurement precision, but also solves the problem that the traditional vacuum helium detection method will damage the battery cells in the battery pack.

The present disclosure relates to a sensor system for monitoring the sealing of the connection between a sensor holder and a sensor that is mounted on the sensor holder. The sensor system includes a sensor holder, a sensor that is mounted on the sensor holder, and a leakage detector with a channel, which is arranged in the sensor holder and consists of one or more straight sections that are mounted perpendicular or parallel to the longitudinal axis of the sensor.

A system for detecting leaks comprises at least one pipeline element, a leak detection device, and a pre-formed, heat-shrinkable sleeve comprising at least one inlet aperture. A method of manufacturing the sleeve comprises the steps of applying a cross-linkable material around a standard-sized sleeve mold, cross-linking the material, removing the cross-linked material from the mold, heating and stretching the cross-linked material around a stretching sleeve mold, allowing the material to cool, and removing the cooled sleeve from the mold. A method of monitoring a leak comprises the steps of receiving the pipeline element in the sleeve and applying heat to the sleeve, whereby the sleeve shrinks and conforms substantially around the profile of the pipeline element and at least a portion of the leak detection device.

A leak detector for checking the sealing tightness of an object to be tested includes a detection inlet to be connected to the object, a first pumping device, and a gas detector. The first pumping device includes a first rough vacuum pump, at least one second rough vacuum pump, and a turbomolecular pump. The gas detector is connected to the turbomolecular pump. The outlet of the at least one second rough vacuum pump is connected to the first rough vacuum pump, between two in-series pumping stages of the first rough vacuum pump.

The disclosure relates to a component device, in particular for a primary supporting component of an aircraft, which comprises a first component element, a second component element, a bonding providing a connection between the first component element and the second component element, a marker substance device configured to dispense a volatile marker gas to the environment when in contact with the surrounding air and being hermetically sealed from the surrounding air by the first component element, the second component element, and/or the bonding if the bonding is not damaged, and a detector device configured to detect the marker gas dispensed by the marker substance device.

A method of testing the seal of transportable containers, such as suitcases, trunks, and cases, which form inside them, in at least one closed configuration, at least one compartment to be seal tested, the method includes the following steps: accommodating a container to be tested, in the closed configuration, in a saturation chamber; dispensing a tracer gas in the saturation chamber; and lowering the pressure value inside the compartment. The method further includes waiting for a preset time, keeping the saturation chamber closed; drawing an air sample from the compartment; and measuring the actual concentration of tracer gas in the air sample drawn from the compartment. Thus, an actual concentration higher than a reference value, correlated to the normal concentration of tracer gas in the atmosphere, can indicate the entry of the tracer gas in the compartment and a condition of at least potential defectiveness of the seal of the compartment of the container.

A leak detection module for checking the seal-tightness of an object to be tested by tracer gas is provided, including a leak detector and a probe configured to be manipulated by a user; and a vision device including a processing and display unit configured to communicate with the leak detector, a securing means configured to secure the vision device on a head of the user, and a viewing surface fixed to the securing means and configured to be placed in a field of view of the user, the processing and display unit being further configured to display, on the viewing surface, information relating to detection of leaks including at least one signal representative of a concentration of tracer gas measured by the leak detector. A method for checking the seal-tightness of an object to be tested by tracer gas is also provided.

A thermal imaging system for use in maintaining a turbine assembly includes a case, a single pixel detector positioned within the case, at least one optical transportation device, and a prism. The optical transportation device is coupled to the case and configured to direct electromagnetic radiation to the single pixel detector. The prism is coupled to the optical transportation device and configured to direct electromagnetic radiation into the optical transportation device and to the single pixel detector. At least the prism and the optical transportation device are inserted into the turbine assembly and the single pixel detector acquires images of the turbine assembly.

A die is supported in a die holder such as a frame or an adapter supported in a frame such that it is operational use in a material deforming operation. One or both of the die and the die holder have at least one gas passage which is substantially closed by at least part of the die. Gas such as pressurised air is directed into an end of the gas passage opposite the die via a hose connected to a gas source. If the die is broken or loose leak paths are available for the escape of gas past the die to or from atmosphere. A pressure sensor connected to the hose detects the change in pressure of the gas and the magnitude of that pressure is used to determine the die condition. Alternatively a flow rate sensor is used to detect a change in the flow rate of the gas in order to determine the condition of the die.
