How to Measure a Thermocouple using the USB-TC DAQ device

The USB-TC has 8 thermocouple inputs and includes out of the box Tracer Daq software for displaying data and saving to disk. Easy to use drivers are also included for Dasylab, LabView, and Visual Studio. Here we have a USB-TC connected to a laptop with a thermocouple connected to channel one. The wires within a thermocouple are made of dissimilar metals. One wire corresponds to the high of channel one, with the other corresponding to the low input of channel one. The USB-TC is compatible with most thermocouple types. In this video we're using a type K which has a yellow wire corresponding to positive, or high, and a red wire for the negative or low. If you accidentally connect the thermocouple backwards, your readings will decrease as the thermocouple is heated. Next, we configure the module using the included instacal application. We select the thermocouple type here. Then, with the included Tracer Daq software we select our channels and sample rate. The USB-TC can sample data at up to 2 samples per sec. It also provides 24-bit resolution for superior measurement accuracy. We can also set alarms and triggers. Now we'll start collecting data. You can now see the data scrolling in real time. And, as we heat the thermocouple, we see the temperature rise. Data can be saved to a file and then opened in a program like excel. As you've seen, taking thermocouple data is quick and easy with the USB-TC DAQ device and included out of the box software. Measurement Computing offers USB as well as PCI, Ethernet, and stand alone data loggers to measure various temperature sensors including thermocouples, RTDs, and thermistors.
