New Uses For Our Current Dyno Thermocouple DAQ System

[BigChief]

Hello,

Currently we are using this setup to collect data in our high temperature dyno.
SCXI-1001 Chassis
4 - SCXI-1120 -> SCXI 1320 units
8 - SCXI-1102 -> SCXI 1303 units
feeding into a PCI-MIO-16E-4 (PCI-6040E) DAQ system.

Also available are a SCXI-1000DC chassis, TC and BNC 2095 terminal blocks, and SXCI-1104 multiplexers.

The sensors we are looking to use have a 4-wire connection consisting of V(excitation),Common Ground, V(output), and V(offset). I would like to know if there is a way we can use the current equipment we have available to provide the 5v excitation source needed, as well as collect the V(output). Any help regarding the appropriate setup or wiring would be greatly appreciated. Thank you in advance

Hi BigChief,

If you're providing an external excitation voltage to your sensors, you should be able to use either the SCXI-1102 or SCXI-1120 module, with their respective terminal block, to perform voltage measurement (provided the signal is within the module's input range). You can wire V(output) and Common ground as input to one of the channels on the terminal block. If the V(offset) is used for zeroing the measurement, you can wire that into a second channel, take the measurement, and subtract that value programmatically. If you're setting up a virtual or global channel, select the measurement type as "voltage" instead of "temperature".

I hope this helps.

Thanks,
