In the default game, all types of scanners (Hyper Optics, Gravitic Scanner, Psychic Scanner, Temporal Scanner and Tachyon Scanner) are the same. A cloaking device cloaks with the same level in each Category, so any of them will work.

So, a level 3 cloaking device protects from level 1 or 2 scanners of all types, but not against a level 3 scanner of any type.

However, you can mod them so that you have different "cloaking devices" with varying types of cloaking require different types of scanners. For example, a Psychic Cloaking Device could protect against Psychic Scanners (of appropriate levels), but not against the other 4 types of scanners. A ship with a Tachyon Scanner I could detect any ship that has just a Psychic Cloaking Device.

The way the abilities work is that each cloaking type and scanner function independantly. If a scanner exceeds any one of the cloaking levels on a ship (taking the highest level of all devices present of the ship), then the scanner can scan the ship. So, you could theoretically have 10 levels in all cloaking except Gravitic, and then a ship with a Gravitic Scanner of any level would be able to detect you. But, a Psychic Scanner 5 would not be able to.
