温度测量ADI

简介：

问：where can i get more information about the products  above ,for example,ad7411
答： Please contact our applications center: 800-810-1742.

问：请问那一种传感器集成了非线性校正和补偿

答： You need to do the non-linear calibration by software, it"s not in the sensor itself.

问：adt7411  具有几种接口
答： There are two kinds of interface, I2C or SPI. But they share the same pins, which means when you use the I2C interface, SPI cannot be used. And vise versa. Please refer to the datasheet for details.

问：ADT7516"s result is averager over 16 convertions,can I adjust the average times to lower or higher? Thanks!
答： No, it"s fixed, you can"t change the averaging number. Or maybe you can do that in CPU.

问：请问测温时集成器件是通过导线连接还是直接附着于被测件合适？谢谢！
答： It"s dependent on the devices you want ot measure. Normally, the remove type temperature sensor has much better performance.

问：我想了解该课题在工控中的应用程度？
答： For digital temperature sensors we discussed today are mainly for diode solution, so the temperature range is mainly limited by diode architecture. Accuracy it can reach today is about +/-0.5 degree.

问：目前，温度测量的前沿技术是什么？在这方面，ADI有什么优势？
答： It"s digital trends, with more functions integrated, smaller package, bigger temperature range, more accuracy...... ADI has advantage in this field on almost all sides.

问：提供的芯片如何于一般的单片机接口，哪儿能买到？
答： You can connect the parts to MCU by SPI interface directly.

问：如何解决温度测量滞后？
答： I am clear about your question. Maybe you are testing quick changing temp, for your application, you have to select the sensor that can response fast enough.

问：有关热电耦温度传感器的冷端补偿，有几种方法？

答： There are two methods: ice-point and the cold junction compensation. For ice-point, it is not fessible, but you can use TMP35 to do the col junction conpensation. Also, AD7719 can be used to sample both of them and compensate it.
