why to use 3 wire at RTD ?
what's the reason for
common wire ?
Answer Posted / prince
RTD's work on the principle of RESISTANCE. The two working
wires might have different lengths, so different resistance.
Third wire is used for compensating the extra resistance so as
to get accurate o/p. Third wire is in parallel connection with
one of the wire. In 4 wire RTD, the compensation is more.
