如何使用Agilent 34970A / 34901A记录电子盒的温度？

正确的是，您很可能不得不对电阻测量进行一些后处理。
热敏电阻的β值是从复数Steinhart-Hart方程得到的常数。
您可以使用任何想要进行转换的软件/编程环境。您可以将Benchlink Datalogger pro与仪器配合使用。
它具有从Steinhart-Hart方程计算温度的数学能力，免费版本没有。
如果您希望我发布它，我有一个BLDL Pro示例。
BLDL确实可以实时进行计算，因此您可以在PC上实时查看计算出的温度。
仪器本身只会显示阻力值。无论您想选择哪条路径，我都乐意帮助您前进。

  Correct, you will most likely have to do some post processing on resistance measurements.  The beta value for a thermistor is a constant derived from the complex Steinhart-Hart equation.  You can use any software/programming environment you want to do the conversion.

You could use Benchlink Datalogger pro in conjunction with your instrument.  It has the math capability to calculate the temperature from the Steinhart-Hart equation, the free version does not.   I have a BLDL Pro example for this if you would like me to post it.   BLDL does make the calculation in real time, so you will see the calculated temperature in real time on the PC.  The instrument itself would just display the resistance values.

Whichever path you wish to choose, I will be happy to assist getting you going.

我正在寻找Agilent 34972A用于将电阻测量值转换为温度值的方程式。
我们正在使用Data logger pro并输入我们自己的方程式，但如果安捷伦使用的方程式足够接近，我们可能不必将自己的方程式用于不同的热敏电阻。
谢谢。



     以下为原文

  I am looking for the equations that are used by the Agilent 34972A to convert the resistance measurements to temperature values.
We are using Data logger pro and inputting our own equations, but if the equation that the Agilent uses is close enough, we might not
have to put our own in for different Thermistors. Thanks.

34970A使用快速分段线性拟合来得到Steinhart-Hart方程的表数据，用于支持的热敏电阻类型。
此拟合精确到0.1 C.对于实际的热敏电阻精度，您必须联系制造商。
精密校准的热敏电阻非常昂贵。
支持热敏电阻分类：2.252欧姆，在25℃的热敏电阻：44004和44033 5千欧，在25℃的热敏电阻：44007和44034 10千欧，在25℃的热敏电阻：44006和44031 *第一模型是+/-单元之间0.2C下互换。
第二个数字是+/- 0.1 C可互换。
请注意，“可互换性”与“准确性”不同。
当您查看两个探针之间的协议时，可以应用互换性。
请参见34970A / 72A和34410数据表中的脚注9：[9]对于总测量精度，请添加温度探头误差。
44006和44031热敏电阻之间的差异是+/- 0.2C互换性与+/- 0.1C互换性。

  The 34970A uses a fast piecewise linear fit to the table data derived from the Steinhart-Hart equation for the supported thermistor types. This fit is accurate to 0.1 C.  For the actual thermistor accuracy, you will have to contact the manufacturer.  Precision calibrated thermistors are very expensive.

Supported thermistor classifications:
2.252 ohm at 25C thermistor:  44004 and 44033
5 Kohm at 25C thermistor:   44007 and 44034
10 Kohm at 25C thermistors:  44006 and 44031
* First model is +/-0.2 C interchangeable between units.  Second number is +/-
0.1 C interchangeable.

Note that "Interchangeability" is not the same as "accuracy".   
Interchangeability applies when you are looking at the agreement between two 
probes.  Please see footnote 9 in the 34970A/72A and 34410 Data Sheets:  [9] 
For total measurement accuracy, add temperature probe error.   The difference 
between the 44006 and 44031 thermistors is +/- 0.2C interchangeability versus 
+/- 0.1C interchangeability.

谢谢Tom，这正是我想要的。

  Thanks Tom,

That is exactly what I was looking for.

Have a great weekend.
