Pt100 RTD vs Pt1000 RTD-Difference between Pt100 and Pt1000 RTD
This page compares Pt100 RTD vs Pt1000 RTD and mentions difference between Pt100 RTD and Pt1000 RTD.
Introduction:
• RTD stands for Resistance Thermometer.
• It has positive temperature coefficient which means its resistance increases with the
increase in temperature.
• For low temperature, RT = [R0*(1 + α*ΔT) ]
• For high temperature, R2 = R1 + R0*α(t2 - t1)
• Where α is resistance temperature coefficient (in units of /0C)
• Both Pt100 and Pt1000 are platinum resistance thermometers.
• The working principle is to measure resistance of platinum element used in its construction.
• They offer excellent accuracy over wide temperature range.
• Both are PTC (Positive Temperature Coefficient) type of resistance thermometers.
• They are manufactures in thin film technology process.
Pt100 RTD
• It uses platinum wire which is wrapped around ceramic core.
• It exhibits linear increase in the resistance with respect to
increase in the temperature.
• Pt100 offers resistance of 100 Ohms at 0 0C.
• Pt100 offers resistance of 138.4 Ohms at 100 0C.
• Sensitivity is 0.391 Ohm per 0C.
Pt1000 RTD
• It also uses platinum wire which is wrapped around ceramic core.
• It also exhibits linear increase in the resistance with respect to
increase in the temperature.
• Pt1000 offers values which are factor 10 higher than Pt100 RTD type.
• Sensitivity is 3.91 Ohm per 0C.
