b) THEORY:
RTD’s are Sensors used to measure temperature by correlating the resistance of the RTD
element .Platinum is the most widely used RTD element due to its accuracy ,stability and
wide temperature range. RTD’s are characterized by linear positive change in resistance
with respect to temperature. They exhibit the most linear signal with respect to
5. The multimeter is placed and the voltage generated is noted down for every 5 oC rise
in temperature.
