Definitions
- the outer hard tube is particularly advantageous if the pump does not suck a transport medium, which is usually air, through the sensor tube, but presses it through the tube in order to give an overpressure in the sensor tube.
- the transport medium and thus the penetrated material can then be moved over a significantly greater distance than would be possible with suction and under vacuum.
- the sensor tube advantageously withstands high external pressure, such as the water pressure in the vicinity of a pipeline laid in the sea.
- the substance to be detected in the event of a leak reaches the diffusion layer through the holes arranged in the outer tube and diffuses through this layer into an inner channel of the tube.
- the ambient air, or the sea water that surrounds the sensor tube only reaches the edge of the diffusion layer through these holes.
- the advantage of the sensor tube according to the invention is that the sensor tube can be used over a greater distance than before and, moreover, can withstand a higher external pressure.
- the diffusion layer is located between an inner, hard transport tube and the outer tube, holes being arranged in the transport tube, which extend from the inside to the diffusion layer.
- the transport pipe consists, for example, of a material that adsorbs only slightly. This has the advantage that the substance in the transport tube, after it has reached it from the outside, is not or only slightly adsorbed by the inner wall of the transport tube. It is then ensured that the substance reaches the sensor largely completely.
- FIG. 1 shows a sensor tube made of an outer hard tube and an inner diffusion layer.
- FIG. 2 shows a sensor tube made of an outer hard tube, a diffusion layer and an inner transport tube.
- Figure 1 shows a sensor tube 1, which is designed for a leak detection and location system (LEOS). It consists of an outer, hard, pressure-stable tube
- Diffusion layer 3 is covered.
- a channel 4 remains free inside the sensor tube 1. If a substance to be detected from the outside, e.g. has emerged from a leak in a pipeline and reaches the sensor tube 1, it penetrates through holes 5, which are arranged in the outer tube 2 and extend to the diffusion layer 3, into the sensor tube 1. The substance then diffuses through the diffusion layer 3 and reaches the channel 4. After the diffusion phase, a transport medium is pumped through the channel 4 for a certain period of time and the substance is detected with a sensor at the end of the sensor tube 1.
- Figure 2 shows a sensor tube 6, which largely corresponds to the sensor tube 1 of Figure 1.
- the diffusion layer 3 is located between an inner hard transport pipe 7 and the outer hard pipe 2.
- Holes 8 are arranged in the transport tube 7, the holes reach inside to the diffusion layer 3.
- the diffusion layer 3 is protected by the inner transport pipe 7 from a high pressure of the transport medium.
- the diffused-in substance passes from the diffusion layer 3 through the bores 8 into the channel 4.
- the transport tube 7 consists of a material that adsorbs only slightly, so that the substance largely reaches the sensor.
