Sealing sleeve with leakage detection
A sealing sleeve with leakage detection has an absorbing layer and a sensor arrangement, wherein the absorbing layer is configured to be attached to a surface of an article containing a fluid, and hose assembly with a connector having a nipple and a socket, wherein an end of a hose is slipped on the nipple and the socket is adapted to establish a fluid tight connection of the hose and the nipple, wherein a sealing sleeve is attached at an intersection of the socket and the hose.
1. A sealing sleeve with leakage detection, the sleeve comprising:
an absorbing layer; and
a sensor arrangement,
wherein the absorbing layer is configured to be attached to a surface of an article containing a fluid and to absorb the fluid in case of a leakage,
wherein the sensor arrangement includes a capacitive humidity sensor,
wherein a thickness of the absorbing layer increases with an amount of absorbed fluid, and
wherein the sensor arrangement is configured to detect a level of saturation of the absorbing layer with the fluid.
2. The sleeve of claim 1 , wherein the absorbing layer includes an EPDM rubber.
3. The sleeve of claim 1 , wherein the sensor arrangement includes a first electrode and a second electrode,
wherein at least a portion of the absorbing layer acts as a dielectric between the two electrodes.
4. The sleeve of claim 3 , wherein the first and second electrodes are attached to an outer side of the absorbing layer, opposite to a side facing a surface of the article.
5. The sleeve of claim 1 , wherein the sensor arrangement is configured to transmit a signal if the level of saturation changes.
6. The sleeve of claim 5 , wherein the sensor arrangement is configured to transmit the signal prior to an emersion of the fluid from the absorbing layer.
7. The sleeve of claim 1 , in the form of a strip.
8. The sleeve of claim 7 , wherein the sensor arrangement includes a first and a second electrode, and
wherein the electrodes are arranged in parallel along the strip.
9. The sleeve of claim 1 , further comprising a protective layer, covering the absorbing layer and the sensor arrangement.
10. A hose connector assembly, comprising:
the sleeve of claim 1 ; and
a hose connector,
wherein the sleeve is preassembled on the hose connector.
11. The hose connector assembly of claim 10 , wherein the sensor arrangement includes a first and a second electrode,
wherein the electrodes are provided as annular rings arranged in parallel around the absorbing layer.
12. A hose assembly, comprising:
a connector including a nipple and a socket,
wherein an end of a hose is disposed on the nipple,
wherein the socket is configured to establish a fluid tight connection of the hose and the nipple,
wherein the sealing sleeve of claim 1 is attached at an intersection of the socket and the hose.
13. A strip, comprising:
an absorbing layer; and
a sensor arrangement,
wherein the sensor arrangement includes a capacitive humidity sensor,
wherein a thickness of the absorbing layer increases with an amount of absorbed fluid,
wherein the absorbing layer is configured to be attached to a surface of an article containing a fluid and to absorb the fluid in case of a leakage,
wherein the sensor arrangement is configured to detect a level of saturation of the absorbing layer with the fluid,
wherein the strip is configured to detect the leakage.
