Table 7.2 YTA0 Effect of Ambient Temperature
Sensor Type Temperature Coefficient
Thermocouples E, J, K, N, T, L, U 0.08°C + 0.02% of abs.reading
Thermocouples R, S, W3, W5 0.25°C + 0.02% of abs.reading
T/C 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 abs.reading
Note1: Ambient Temperature Effect per 10°C change is
±0.1% or ±(temperature coefficient/span), whichever
is greater.
Note2: The “abs.reading” on Table7.2 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, absolute (250–273.15).
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 Coefficient/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
