找到PXI到PCI适配器并连接到计算机?

亲爱的专家，这对您来说是一个棘手的问题。
我要在世界各地进行几次室外温度测量。
因此，我乘坐34972A飞机，几台PT100和许多电缆。
这很重，因此很省钱。
我梦想着可以通过Wifi操作的PT100并摆脱所有电缆。
简单没有？
但我一直在挖掘互联网，似乎没有人以0.05°C的精度销售这种设备。
所以我想我可以自己建一个。
为了达到准确性，我需要一个至少5½位的精确数字万用表：选项1：U2741A有一个USB连接，我可以连接到像Raspberry PI这样的小型计算机，还可以连接一个Wifi模块。
问题1：Raspberry PI是Linux世界，没有U2741A的驱动程序问题2：Raspberry PI只有一个USB端口。
解决方案1：使用Windows嵌入式计算机......可能但很重。
选项2：M9181A非常轻，采用直流供电。
一个梦 ！
问题1：找到PXI到PCI适配器并连接到计算机???
选项3：34972a剥离重型外壳使用LAN接口将其插入wifi路由器。
相当昂贵。
选项4：让KeySight先生开发它：拿M9181A，添加电池，添加34972A的LAN模块，添加wifi芯片就可以了。
这不是一个伟大的R＆amp; D想法吗？
我相信它会成为热门话题。
更严重的是，没有人有好主意解决这个问题吗？
问候，文森特

  Dear Experts,  

Here is a tough question for you. I’ve to make several outdoor temperature measurements all around the world. Therefore I’m traveling by plane with a 34972A, several PT100 and a lot of cables. This is heavy and thus costy. I’m dreaming of a PT100 that can operate by Wifi and get rid of all cables. Simple no ? But I’ve been digging internet and no one seems to sell such device with a precision of 0.05°C. Therefore I’m thinking that I could build one myself.  

To meet the accuracy, I need a precise DMM with at least 5 ½ digit :

OPTION 1 : U2741A has a USB connection that I can connect to a tiny computer like Raspberry PI and also connect a Wifi Module.  
            Issue 1 : Raspberry PI are linux world and doesn’t have driver for U2741A
            Issue 2 : Raspberry PI have only one USB port.
            Solution 1 : Use a Windows embded computer  …  possible but heavy.

OPTION 2 : M9181A is very very light and it is DC powered. A dream !
         Issue 1 : Find a PXI to PCI adaptor and connect to a computer ???

OPTION 3 : 34972a strip the heavy casing a use the LAN interface to plug it to a wifi router. Rather expensive.

OPTION 4 : Ask mister KeySight to develop it : Take the M9181A, add a battery, add the LAN module of the 34972A, add a wifi chip and  you’re done. Isn’t it a great R&D idea ? I’m sure it is going to be a hit.


More seriously, doesn’t anyone has a good idea to solve this issue ?

Vincent
