For a numerical physical quantity v, because of the measurement imprecision, the measurement result ṽ is, in general, different from the actual value v of this quantity. Depending on what we know about the measurement uncertainty ∆v def = ṽ − v, we can use different techniques for dealing with this imprecision: probabilistic, interval, etc. When we measure the values v(x) of physical fields at ...

An non-contact type application on the permanent magnet and linear Hall-effect sensors gauging rotary system is introduced in this paper. For such a contactless system, there will be low wear exhaust. This leads to a longer life span in association, and in particular, high reliability to achieve continuous use. The main component of the angular gauge depends on the Hall voltage under the rotati...
