Multi-probe sender and tank having the same

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.
