A method for providing an enhanced estimate of reference barometric pressure. The method uses multiple, dissimilar pressure references, such as in airport weather stations, personal weather stations, and wireless terminals such as smartphones, in order to provide the enhanced estimate of reference barometric pressure. The method generates an enhanced estimate of reference barometric pressure based on a first estimate of reference barometric pressure from a first pressure reference network made up of airport weather stations, for example. The method also uses a second estimate of reference barometric pressure from a second pressure reference network made of up personal weather stations, for example, and a third estimate of reference barometric pressure, also from the second network. The first, second, and third estimates of reference barometric pressure are combined such that both measurement accuracy and timeliness are improved in the resulting, enhanced estimate.

A pressure gauge includes: an outer container defining an outer chamber set to a reference pressure (Pr); an inner container disposed in the outer container; and a tube setting the inside of a first inner chamber of the inner container to a measurement pressure (Px). The inner container includes: a cylindrical rigid wall portion; first and second pressure receiving plates that displace due to a differential pressure between the reference pressure and the measurement pressure; a bellows partitioning the inner container into the first inner chamber and a second inner chamber; and a pressure detection element disposed in the second inner chamber and detecting the measurement pressure based on the displacements of the first and the second pressure receiving plates. The outer chamber and the second inner chamber are set to the reference pressure of a high vacuum that is lower than a lower limit of the measurement pressure.

A method for capturing a tensile force exerted during the pulling of a pipe or line during installation, includes capturing a strain on the pipe or line via one or more sensors arranged on the pipe or line. Multiple strain sensors may be arranged such that they are offset at various angles across the circumference of the element being installed. One or more sensors may be mounted to a towing head for pulling the pipe or the line during installation.

A monitoring device (118) for monitoring the leak-tightness of a vacuum-insulated system has a corrugated bellows (108) which is connected in terms of flow to an evacuated space (104) of the vacuum-insulated system in such a way that, in the event of an increase in pressure in the evacuated space, the length of the corrugated bellows (108) is adjusted beyond a threshold value. A position detector (113) connected to an energy store (115) responds to the change in length of the corrugated bellows and outputs a signal. The position detector outputs a signal to a display device (116), which provides an indication if a leak in the vacuum-insulated system occurs.

A gas densimeter for monitoring a pressure or density of a gas in a gas chamber with a housing having a first housing chamber and a measuring chamber, a first coupling, via which the measuring chamber can be connected to the gas chamber, at least one reference bellows, which is connected directly or indirectly in particular to a transmission element, and at least one transmitting and/or monitoring unit, which is or can be operatively connected directly or indirectly to the transmission element. In this regard, the measuring chamber has a gas-permeable connection to the gas chamber via the first coupling and the reference bellows forms a reference chamber filled with a constant amount of a reference gas. A surface section covering the reference chamber is provided or reachable at least partially within the first housing chamber or measuring chamber as a measuring surface for the gas from the gas chamber.
