Cold junction rtd
WebThis method usually employs a self-compensating cold junction electrical bridge circuit as shown in Figure 2. This system incorporates a … WebThe resistance temperature detector, or the RTD, is a sensor whose resistance changes with temperature. Typically built of a platinum (Pt) wire wrapped around a ceramic bobbin, the RTD exhibits behavior which is more accurate and more linear over wide temperature ranges than that of a thermocouple.
