A sensor line for monitoring for and locating leaks in an installation, in which chlorine escapes to the area surrounding the installation if there is a leak. The sensor line contains a carrier pipe. The wall of the carrier pipe has openings which are closed by at least one layer which is permeable for chlorine and contains a halogen-containing siloxane rubber.

Sensor line for monitoring for and locating leaks and method for its production

A method for producing a collecting line, and a collecting line produced according to the method is provided for detecting and locating an agent discharging into the environment of the collecting line in case of leakage. Such a collecting line has a carrier pipe, the wall of which is equipped with openings that are sealed by an elastic material that is permeable for the agent. Accordingly, a hose made of the permeable elastic material, the inside diameter of which is smaller than the outside diameter of the carrier pipe, is elastically expanded by creating a pressure difference between the interior and the exterior of the hose. The carrier pipe is inserted into the radially expanded hose, and the radially expanded hose is attached to the outside surface of the carrier pipe by reducing the pressure difference.

Method for the production of a collecting line for detecting and locating an agent discharging into the environment of the collecting line in case of leakage

A method and a device for detecting a pulse-type mechanical effect at a system component, include continuously recording an operating noise in the system component with a sensor disposed at the system component and converting the operating noise with the sensor into a measured signal subjected to a mathematical transformation. A sliding mean is calculated by determining quantiles from determined transformations and an evaluation function, which displays an application of the pulse-type mechanical effect on the system component, is derived from the sliding mean.

Method and device for detecting a pulse-type mechanical effect on a system part

A method and device detect a position of a pulsed mechanical effect on a plant component. An operating noise in the plant component is continuously recorded by sensors which are arranged on the plant component and converted by the above into a measured signal. The measured signals of the sensors undergo a transformation in a first time window. A first evaluation function is derived from a plurality of first transformations determined in this manner, the evaluation functions display an appearance of the pulsed mechanical effect. Accordingly, when detecting an effect following the second shorter time window having the same algorithms, second transformed and respectively, second evaluation functions are derived, from which, respectively, one time point is determined. Wherein the sound signal produced by the effect impacts upon the sensor. From there, running time differences produced between the sensors can be exactly reconstructed on the position of the effect.
