Sensor Resistance Temperature Tables

▓ NTC (Negative Temperature Coefficient) is the negative Percent resistance change per degree C. To determine

The resistance tolerance of a precision thermistor at any times the NTC.

As an example, a Curve A thermistor with a temperature Tolerance of ±1℃ over the temperature range 0° to 70℃ would have the following resistance tolerance: 0℃=±5.1%;25℃=±4.4%;70℃=±3.4% RT/R25

Ratio is the resistance at temperature divided by the resistance at 25℃. To determine the resistance at other temperature points, multiply the coefficient by the R25 value.

Ratio TOL(Tolerance) is the resistance tolerance at a temperature point due to slope variance from the nominal R-T Curve. This tolerance applies to thermistors point- Matched to a single temperature point.

The ratio tolerance is added to the percent resistance tolerance at the point- Matched temperature.

NTC（負溫度係數）是負百分比電阻變化每度℃.要確定一個精確的電阻誤差的熱敏電阻的溫度系數。例如一個曲線 A熱敏電阻與溫度誤差 ± 1℃以上的溫度範圍 0 °至70℃，有以下的電阻誤差值：0℃= ± 5.1％; 25℃ = ± 4.4％; 70℃ = ± 3.4％ , RT/R25 比率是電阻溫度除以電阻在25℃。為了確定電阻值在其它位置的溫度點，乘以係數由R25℃的值。比率Tol（誤差）是電阻誤差的溫度點，其溫度變化RT曲線。適用於熱敏電阻誤差點的一個溫度點。 (內容說明謹供參考)
