Ambient Temperature Effect per 50 °F (28 °C)
• ±(0.05% URL + 0.125% of span) spans from 1:1 to 30:1
±(0.06% URL – 0.175% of span) spans from 30:1 to 100:1
Stability
• ±0.125% URL for five years for ±50 °F (28 °C) ambient temperature
changes, and up to 1000 psi (6,9MPa) line pressure.
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 212 °F (–40 to 100 °C)
Accuracy (including Linearity, Hysteresis, Repeatability)
• ±1.0 °F (0.56 °C)
Ambient Temperature Effects per 50 °F (28 °C)
• ±0.90 °F (0.50 °C) for process temperatures from –40 to 212 °F (–40 to
100°C)
Stability
• ±1.0 °F (0.56 °C) for one year
