Table7.2 Temperaturecoefcient
Sensor Type TemperatureCoefcient
Thermocouples E, J, K, N, T, L, U 0.08°C + 0.02% of abs.reading
Thermocouples R, S, W3, C 0.25°C + 0.02% of abs.reading
Thermocouple B
100°C ≤ Reading < 300°C 1°C + 0.02% of abs.reading
300°C ≤ Reading 0.5°C + 0.02% of abs.reading
RTD 0.08°C + 0.02% of abs.reading
mV 0.002 mV + 0.02% of abs.reading
ohm 0.1Ω + 0.02% of reading
Note 1: The “abs.reading” for thermocouples and RTD means the absolute value of the reading in °C.
Example of “abs.reading”
When the temperature value is 250 Kelvin, “abs.reading” is 23.15.
|250−273.15|= 23.15
Note 2: Ambient Temperature Effect per 10 °C change is ±0.1% or ±(temperature coefcient/span), whichever is greater.
Example of Ambient Temperature Effect
Conditions:
1) Input Sensor: Pt100
2) Calibration Range: −100 to 100°C
3) Reading value: −50°C
Ambient Temperature Effect per 10°C
Temperature Coefcient/Span=(0.08°C+0.02/100×|−50°C|)/{100°C−(−100°C)}= 0.00045 → 0.045%
Therefore, Ambient Temperature Effect is ±0.1%/10°C
Note 3: See Table 7.5 for R1 option type.
