Device for testing sealing of at least a part of a double-door sealed transfer system between two closed volumes, the system including a first flange and a and a second flange capable of being rigidly connected to one another, and a first door and a second door normally sealing openings respectively defined by the first and the second flanges, the device including a casing including a cavity provided with an opening, mechanical connection to a flange so that the cavity is closed by the flange and the door and an inflatable joint which, in the inflated state, is in contact with the flange and ensures a sealing allowing to verify the sealing between the flange and the door.

A gas leakage meter (100) for use onsite in a process plant comprises a housing (110) with an inlet (101), an outlet (102) and an inlet nozzle (111) fluidly connected to a unit to be tested (3) through a downstream connector (1040) and to the inlet (101), the housing (110) being filled with a liquid to a level (10). An inclined pipe (120) is arranged such that, in use, test gas released from the inlet nozzle (111) raises through a liquid and the inclined pipe (120) to a gas-collecting chamber (122) at an upper end of the inclined pipe. (120). The gas-collecting chamber (122) has a gas release valve (150; 170) for releasing test gas before a test period. Embodiments where the inclined pipe (120) is mounted on a pivot and alternative gas release valves (150, 170) are also disclosed.

An evaporated gas leak diagnosis method using an active purge pump is provided to detect a leak of the evaporated gas from a canister in a fuel system. The method includes diagnosing a failure of an active purge pump based on a signal generated by a pressure sensor installed on a vent line that extends from the canister to the atmosphere. The active purge pump is mounted on a purge line for connecting the canister with an intake pipe.

Wearable protection device (1) comprising at least one inflatable bag (8) configured to assume alternately a rest configuration, wherein it is in a deflated state, and an active configuration, wherein it is in an inflated state and inflation means (14) in fluid communication with the inflatable bag (8) and configured to introduce therein an inflation fluid once they have been triggered. The wearable protection device (1) further comprises at least one pressure detecting device (26) associated with the at least one inflatable bag and configured for directly or indirectly detecting the pressure inside the at least one inflatable bag (8). A further object of the present invention is a method for evaluating if an inflatable bag (8) of a wearable protection device (1) is reusable once it has been inflated.

The present invention relates to a system (20; 20′) for detecting leaks for a part having a permeable zone, said system comprising: a test chamber (22, 22′) configured to receive the part to be tested; a device (24) suitable for varying the pressure in the test chamber and/or in the part to be tested; a measuring device (26) for measuring a physical quantity representative of the leak level; characterised in that said system (20; 20′) comprises a main pipe (30) configured to cooperate with the permeable zone of said part, said main pipe (30) having one end (30a) which communicates with the permeable zone, while the other end (30b) of said pipe (30) opens outside the test chamber (22; 22′).

A device for inspecting waterproofness of an object includes a lower jig and an upper jig configured to support the object to be inspected, inspection modules configured to contact an outer surface of the object, and an air compressor configured to supply air to the inspection modules. Each of the inspection modules includes a jig that is configured to contact the outer surface of the object and defines a chamber configured to communicate air, a valve defining a passage in communication with the chamber, an air supply line connecting the valve to the air compressor and configured to guide air to the passage, and a pressure sensor connected to the valve and configured to detect an air pressure in the passage.
