Process Temperature
(RTD)
Specification for process temperature is for the transmitter portion only. Sensor errors caused by
the RTD are not included. The transmitter is compatible with any PT100 RTD conforming to IEC
751 Class B, which has a nominal resistance of 100 ohms at 0 °C and
∝ = 0.00385. Examples of
compatible RTDs include the Rosemount Series 68 and 78 RTD Temperature Sensors.
Sensing Range
• –40 to 1200 °F (–40 to 649 °C)
Accuracy (including Linearity, Hysteresis, Repeatability)
±1.0 °F (0.56 °C)
