Dear all,
I have a project where I have to measure the temperatures in various location of a pipe wall. The pipe is part of an electrical circuit (an electrical current will pass through). For acquiring data, I have a system in the following configuration: DAQ6024Ecard and SCXI1000 chassy with -3*SCXI1102/SCXI1303 and SCXI1125/SCXI1320. Unfortunately, it was taken for us couple of months to figure out that the system is is NOT working because of non isolated channels from SCXI1102/1303.
On the other hand we perform some test with SCXI1125/SCXI1327 and SCXI1121/SCXI1327 and the results are:
Reading temperatures with SCXI 1125/1327- K thermocouples, CJC built in -indicate correct readings with TRaditional Legacy and wrong with DAqmx (for example 125 deg C in TDAQ and 700 deg C in DAQMx - the values were checked with a high accuracy voltmeter and 125 deg C value was confirmed).
Reading temperatures with SCXI 1121/1327- K thermocouples- CJC built in- indicate indicate correct readings with DAqmx and wrong with
Traditional legacy daq(for example out of range deg C in TDAQ and 91 C in DAQMx - thevalues were checked as well with a high accuracy voltmeter and 91 C was confirmed).
Now, my system has for the moment 104 channels disposed as: 8 channels for high voltages and 96 for temperatures readings.
The question is: what you advice me for a hardware configuration which allow me to keep 90-104 channels for my measurements? Should I continue with SCXI or there is some platform more suitable for my application.
Thank you,
