铂电阻 温度传感器 Pt100

时间:2019-09-04   来源:vr赛车电子  编辑:热敏电阻厂家  浏览:
本标准中使用的温度/电阻关系如下:
 - 适用范围-200°C至0°C:
Rt = R0 [1 + At + Bt 2 + C(t – 100 ºC) t 3]
- 适用温度范围为0°C至850°C:
Rt = R0 [1 + At + Bt 2 )

A = 3.9083 x 10-3 °C -1
B = -5.775 x 10-7 °C -2
C = -4.183 x 10-12 °C -4

对于满足上述关系的电阻温度计,温度系数α定义为:
α= (R100 - R0 ) 具有确切的价值0.00385055 °C
100 x R0
where
R100是100°C时的电阻
R0是0°C时的电阻
公差,Pt100和Pt1000

电阻温度计的公差值分类如下:
 公差类  公差(°C)
 A
    B
 0.15 + 0.002 |t|*
    0.3 + 0.005 |t|
*| T | =以度为单位的温度模数
摄氏温度不考虑标志。
