A detector arrangement for detecting humidity or water in a structure. The detector arrangement comprises a one-piece, substantially non-conductive detector plate (1), installable on the surface of a structure, the detector plate comprising parallel sensors (2a, 2b, 3a, 3b), secured apart from one another such that water or humidity causes the resistance between said sensors to decrease.

Description

DETECTOR ARRANGEMENT FOR DETECTING HUMIDITY OR WATER IN STRUCTURES
The invention relates to a detector arrangement for detecting humidity or water in a structure, the detector arrangement comprising at least two sensors positioned apart from one another, any water or humidity between the sensors causing the resistance between the sensors to decrease and thus allowing the presence of water or humidity to be detected.
Different indicators for indicating the presence of humidity or water before any damage to a structure has occurred are used to prevent harmful humidity in structures. Typically this is based on a construction that indicates a short circuit caused by humidity or a resistance lower than that of a dry state by different detectors. Such solutions are known e.g. from Finnish patent applications 933813 and 950708, Finnish utility model application U940293, Swedish publications 375 395, 454 024, and 467 023, and German publication 37 44 233.
All these publications disclose solutions in which separate detectors are used, the detectors being formed either by two adjacent conductors or by adjacent contact strips, whereby humidity or water affects a resistance between these. A drawback in all these solutions is the difficulty of installing separate detectors such that they sufficiently well cover the possible areas that release humidity. Furthermore, installing these in structures or e.g. under floor or wall coatings is difficult, and consequently they are difficult to use.
It is an object of the present invention to provide a detector arrangement which is easy to install and easy to use under different circum- stances. The detector arrangement of the invention is characterized in that the detector arrangement comprises a one-piece, substantially non-conductive detector plate, installable on the surface of a structure, that substantially the entire surface of the detector plate comprises parallel sensors, secured apart from one another such that water or humidity causes the resistance between said sensors to decrease.
It is an essential idea of the invention that the detector is formed of a sheet-like material, such as floor or ceiling coating or corresponding substantially insulating material, on either or both surfaces of which, or possibly inside the sheet-like material, sensor conductors of conductive material have been installed apart from one another over the entire surface of the detector plate such that humidity or water causes the resistance value between the sensors to decrease and thus allows the humidity or wetness to be detected. If the sensors are inside the material, openings from which water can get in contact with the sensors are arranged in the material, either on its one side or through it, thus allowing detection. The detector plate may alternatively be of a porous material, such as e.g. rough cork mat, corrugated board or other corresponding material which as such is not substantially conductive, but into which water is absorbed thus enhancing electricity flow between the sensor conductors.
It is an advantage of the invention that a detector structure impie- mented in this manner can be produced as a mat-like or film-like product with sensors forming onto the product all the time as the sheet-like substantially non-conductive material is formed on the production line. A further advantage of the invention is that the entire area of a floor or a wall can be protected as sensors are arranged on the entire surface of the detector plate and, in order to connect the alarm system, it is sufficient that every second sensor be coupled together and the formed sensor pairs are coupled by their own wire to the actual alarm which indicates if humidity or water affects some point of the detector plate between the sensors.
The invention will be described in more detail in the attached draw- ings, in which
Figure 1 schematically shows an embodiment of the detector arrangement of the invention,
Figure 2 schematically shows another embodiment of the detector arrangement of the invention, and Figures 3a and 3b show a third embodiment of the detector arrangement of the invention.
Figure 1 schematically shows an embodiment of the detector arrangement of the invention in section. In this embodiment, the detector arrangement forms a floor coating comprising a detector plate 1 of plastic mate- rial. The thickness of the detector plate 1 is equal to that of conventional floor coating and in principle it can be a normal plastic mat or the like. The lower surface of the detector plate 1 comprises sensors 2a and 2b, arranged side by side, the sensors being in this case e.g. stripes containing carbonous material and formed on the lower surface of the detector plate 1 during production by pressing or a similar technique. As is evident from the Figure, such stripes are in pairs on the lower side of the detector plate 1 apart from one another thus forming sensor pairs.
In this embodiment the detector plate 1 of the detector arrangement operates as floor coating, a humidity or water alarm being generated by coupling every second sensor together, the sensors 2a forming one series of sen- sors, and the sensors 2b forming a second series of sensors, alternating on the lower surface of the detector plate 1. When each sensor series is coupled separately by its own wire to a separate alarm device, they form an alarm solution in which humidity or wetness at a point on a floor causes an alarm as the resistance between the sensors 2a and 2b decreases. Figure 2 in turn shows an other embodiment of the detector arrangement of the invention in section. This embodiment involves a detector arrangement with the detector plate 1 operating as a water insulation. In this embodiment, both sides of the detector plate 1 comprise sensors 2a, 2b, and 3a, 3b, corresponding to Figure 1. The sensors are coupled in the same way as in Figure 1 , such that the sensors on the same side of the detector plate 1 , i.e. the water insulation mat, are coupled together alternately to form sensor series. In this case humidity can be indicated separately on both sides of the water insulation mat, whereby the connecting wires of the sensor series on one side of the mat are led to the alarm separately from the conductors of the sensor series on the other side. In this way possible water leakage onto the water insulation mat can be detected, and also possible humidity in the structure between the water insulation mat and a wall or the floor, the side on which the water or humidity is detected also being immediately indicated. If needed, the sensor series on both sides of the detector plate 1 can also be coupled together such that an alarm originating from either series gives one single alarm. In this embodiment the sensors 2a, 2b, and 3a, 3b are thin strips formed by a metal sheet and secured to the detector plate 1 either during its production or separately after the coating sheet is completed.
Figures 3a and 3b schematically show a third embodiment of the detector arrangement of the invention. The sensors 2a and 2b are arranged inside the detector plate. In this embodiment the sensors 2a and 2b can be e.g. thin metal threads, suitable metal strips, or similar conductive material, installed inside the detector plate 1 during its production. In order for the appearance of humidity or water to give an alarm in this embodiment, openings 4 are formed in the detector plate by the sensors 2a and 2b as shown in Figure 3a such that water or humidity comes into contact with the sensors 2a or 2b from both sides of the detector "plate 1. Figure 3b in turn shows an embodiment in which the detector plate 1 comprises openings 4' extending only from its one side to the sensors 2a and 2b, water or humidity coming into contact with the sensors 2a and 2b only from one side of the detector plate, the de- tector plate 1 simultaneously operating as a water impermeable layer.
The detector arrangement of the invention is simple and easy to make e.g. when producing plastic mats or the like by forming parallel sensors on the surface of the detector plate 1 formed by the actual mat material, the sensors being of a suitable conductive material, such as metal thread, metal sheet, metal strips or other metal-containing strip-like materials, covering the entire width of the floor coating in the machine direction. Sensors may further be made with paint or plastics of conductive material, metal particles, coal, carbon black or other conductive filler constituting the conductive component. The sensor can also be made of chemical materials that themselves are suffi- ciently conductive, such as a suitable softener for plastic material or a mixture of a softener filler.
Substantially insulating material designed as actual floor or ceiling coating or material made separately as a water insulation or the like can be used as the detector plate. Furthermore, e.g. rough cork mat, corrugated board or other corresponding sheet-like material suitable as sound insulation under the actual coating, such as parquet, to which the sensors are secured or formed in a suitable form. The sensors can either be glued afterwards or be formed of thread-like or strip-like conductors in connection with the production of e.g. rough cork mat and corrugated board. The detector plate can be either of a fully fillm-like material, or, as is obvious from the above, also of a thicker material. Similarly the detector plate can operate either as such as a visible coating or as a sound or humidity insulation installed between a visible coating and the structure, or a mere detector, and also possibly as a detector arranged inside the structures. In the above description and in the drawings the invention has been described by way of example only, and is in no way restricted to it. It is essential that the detector arrangement comprises a detector plate of substantially non-conductive material, the plate preferably simultaneously acting as a floor or ceiling coating or an insulation layer, and the detector plate comprises par- allel sensors of conductive material arranged apart from one another in such a way that water or humidity have an effect between the sensors thus causing an increase in the conductivity between them, i.e. a reduction in the resistance between them, on the basis of which the detection of humidity or water can be indicated by a separate alarm device.
