open thermocouple detection scxi 1328

[Angelantoni]

Hi all

Am using SCXI 1328 terminal blocks for measurment of temperature from thermocouple, for the sake of providing high accuracy in the thermocouple reading the scxi 1328 terminal block, i guess do not have built in open thermocouple detection circuitry. It is mandatory for my application to detect open thermocouple, Am using scxi 1125 signal conditioning module, is there any way in which i can not harm the accuracy of reading and still detect open thermocouple's? can i use any other modules with similar property as scxi 1328.

Hi Angelantoni,

You can get further information on implementing your own disconnected circuitry detection from the following article:

Disconnected Signal Detection in Single-Ended Mode with DAQ Device

The following article discusses open thermocouple detection and associated effects, as well as the SCXI modules which offer this feature:

Open-Thermocouple Detection

Thanks,
