USB-2001-TC Single Channel Thermocouple Measurement Device

Digilent's measurement computing USB-2001-TC is a USB-based thermocouple measurement device. The USB-2001-TC is a USB device that takes measurements from type J, K, R, S, T, N, E, and B thermocouples. The thermocouple type is software programmable and stored on the device. A 20-bit ADC processes the data conversions. The USB-2001-TC is equipped with open thermocouple detection (OTD). With OTD, any open-circuit condition at the thermocouple sensor is detected by the software. An open channel is detected by driving the input voltage to a positive value outside the range of the thermocouple output. The software recognizes this as an invalid reading and returns the value “OTD.” Users can quickly connect a thermocouple to the USB-2001-TC with a standard miniature connector. This device is USB-powered and requires no external power.

Software support includes DAQami, an out-of-the-box application for data logging, visualization, and signal generation. Data can be viewed in real-time or post-acquisition on user-configurable displays. Drivers are included for the most popular applications and programming languages, including Visual C++®, Visual C#®, Visual Basic® .NET, DASYLab®, LabVIEW™, and Python™.
