The Nokeval 620S is a compact, 2-wire temperature transmitter specifically designed for use with Pt100 sensors. It features extreme accuracy achieved through signal linearization with an error of only 0.05% of the span. The device allows one unit to replace several narrower range transmitters without reducing measurement precision.
