摘要： A leak detection system and method are disclosed. The capacitance of a leak detection cable is changed by a leaking liquid. A capacitance measuring circuit detects changes in the capacitance of the cable and thereby detects the presence of a leak. The capacitance measuring circuit includes an inverter, a current source, a comparator, and a timer. The inverter inverts a DC voltage to produce a mirror-image inverted DC voltage. The current source produces a constant current proportional to the mirror image inverted DC voltage and supplies the constant current to the cable such that the cable is charged. A comparator compares the voltage across the cable to the input voltage and produces a match signal when they are equal. A timer which is responsive to the match signal measures the time required for the cable to be charged. The capacitance of the cable is directly proportional to the charge time.

摘要： A device for testing the presence of air in a steam sterilizer for porous loads, comprising four porous masses (10) each formed from a stack of single rectangular sheets of spun-bonded polypropylene, each mass being contained and enclosed by perforated shrink wrapping film to produce a block of typically some 4 cm in height and typically some 15 cm square. Interposed between the masses (10) are envelopes (13) of a similar material, each containing a thermocouple and conductor leads. The assembled stack is contained by upper and lower end plates (15) and resilient side panels (16) which serve as clamps to compress the stack. When placed in a steam sterilizer under operating conditions, the device serves to test the accuracy and efficiency of the sterilizer by taking accurate temperature readings from the thermocouples placed at the different heights, and by comparing these readings to the temperature in the condensate drain passage of the sterilizer.

摘要： The invention concerns a pipeline system comprising an inner medium-conveying pipe (1), an outer pipe (2) surrounding the inner pipe at a spacing, and thermal insulation filler material in the space between the two pipes. The pipeline system further comprises a system containing a sensor line (4) for detecting and locating leakages. The material used for the sensor line is an alloy which has a low and largely constant temperature coefficient and a resistance which is low enough for a process for locating leakages by measuring the propagation time of a reflected pulse to be carried out with the sensor line. The resistance value of the alloy is furthermore high enough for leakages to be located by measuring resistance. The material used for the sensor line is preferably a CuNi10-type copper-nickel alloy.

摘要： A device for leakage detection in pumps or other assemblies for handling electrically conductive, pumpable products, e.g. previously sterilized liquid foods, has a diaphragm which includes, on the one hand, a liquid-tight layer (15) which is located in contact with the product, and, on the other hand, an electrically conductive material layer (16) discrete from the product. The conductive layer (16) is, via a conductor (19) with an indicator (20), electrically connected to the product, and when cracks occur in the diaphragm so that the product comes into contact with the electrically conductive layer, a closed current circuit will be made, which immediately indicates the leakage and makes it possible to avoid the leakage resulting in a contaminated and destroyed product.

摘要： The invention concerns a device for detecting and locating leakage fluids in sealing systems, said device being characterized by a single-layer flat structure (4) which comprises electrically conductive particles and/or fibres and is disposed all-over the exterior of a sealing region to be monitored. The flat structure comprises an area-specific electrical resistance which, when wetted with an electrically conductive fluid, decreases in the region of the wetting and, when wetted with an electrically non-conductive fluid, increases in the region of the wetting. The flat structure (4) is further provided with a plurality of measuring contacts (5, 6) which are connected via one or a plurality of bus transmission lines to a measuring and evaluating arrangement (9) by means of which the electrical resistance of the flat structure (4) and/or the potential distribution can be measured in relation to a counter electrode disposed on the interior of the sealing region to be monitored, and a variation in the local resistance distribution and/or potential distribution within the flat structure (4) can be determined.

摘要： The invention relates to a method and an apparatus for checking leakages in a closed container having at least one flexible wall. According to the method, in a first operation a container (1) is disposed with one of its edge surfaces or sides (6) engaging against a printed circuit board (5), which has at least two conductors (7, 8) in closely spaced relationship facing towards the container (1), a first excess pressure being generated in it for a given time interval, subsequent to which it is turned over or twisted round in a second operation, and a second excess pressure is generated in it, thus achieving, in the case of a leaking container, that the contents in the portion of the container (1) covered by the contents are pressed outwards, and in contact with the printed circuit board result in that decreased resistance can be indicated in the circuit formed by the conductors on the printed circuit board, thus indicating leakage. The inventive apparatus includes a printed circuit board (5), against which a container (1) to be tested may be placed, and which is provided with at least two conductors (7, 8), a means (12) coacting with the printed circuit board for generating an excess pressure, and at least one indicating means (11) for determining change in resistance in the conductors (7, 8) extending on the printed circuit board (5).
