Abstract

A multi-probe sender may include a multi-probe having a reed switch arrangement in which reed switches form a level-sensitivity obtaining interval at which a value overlap is prevented in consideration of a resistance-value tolerance range, and having a probe layout forming an intersection interval at which value interference is prevented in consideration of an interval overlap of the reed switches.

First claim

What is claimed is:

1. A multi-probe sender comprising:
a multi-probe having a reed-switch arrangement in which reed switches form a level-sensitivity obtaining interval at which a value overlap is prevented in consideration of a resistance-value tolerance range, and having a probe layout forming an intersection interval at which value interference is prevented in consideration of an interval overlap of the reed switches,
wherein the multi-probe comprises three probes, including first, second and third probes each having the reed switches, and a combination of the first, second and third probes form the probe layout,
wherein the multi-probe is coupled with a magnetic float moving up and down along the first, second and third probes, and the magnetic float is provided with a permanent magnet that forms a resistance detection surface along with each of the reed switches,
wherein first, second and third positioning holes are penetrated into the magnetic float, thus forming through holes, and the first, second and third probes are positioned in the first, second and third positioning holes, respectively.

2. The multi-probe sender of claim 1 , wherein the reed-switch arrangement is formed on the probe, and the probe layout is applied to a probe combination.

3. The multi-probe sender of claim 1 , wherein each of the first, second and third probes form the reed-switch arrangement.

4. The multi-probe sender of claim 1 , wherein the combination is formed such that the first, second and third probes are at an angular interval of 120° relative to each other.

5. The multi-probe sender of claim 1 , wherein the first, second and third positioning holes are at an angular interval of 120° relative to each other.

6. The multi-probe sender of claim 1 , wherein the multi-probe is coupled with a head, and the head transmits a resistance detection value of the corresponding reed switch depending on a change in position of the magnetic float to an outside.

7. The multi-probe sender of claim 6 , wherein a fixer is provided on a junction between the multi-probe and the head, and the fixer fixes the multi-probe and then couples the multi-probe with the head.

8. A tank comprising:
the multi-probe sender of claim 1 ;
the magnetic float moving up and down along the multi-probe;
a head to which a fixer is secured, the fixer being coupled to the multi-probe; and
a supporter coupled to the head,
wherein the multi-probe sender is vertically installed towards a bottom of an internal space that is to be filled with liquid.

9. The tank of claim 8 , wherein a width of the tank is greater than a height of the tank.

10. The tank of claim 8 , wherein a detection value of the multi-probe sender is transmitted to a cluster display configured to display a flow level.

11. The tank of claim 10 , wherein the multi-probe sender is connected with the cluster display via a cable connector.

12. The tank of claim 8 , wherein a pump is provided in the internal space to pump up the liquid and then discharge the liquid out from the internal space.

13. The tank of claim 12 , wherein the liquid comprises fuel or urea water.
