Description
The USB-TC01, identified by part numbers 781314-01, 781314-02, and 781314-03, is a thermocouple input device that interfaces via a Full-Speed USB connection. This device is designed to facilitate precise temperature measurements by supporting a single thermocouple channel. It utilizes InstantDAQ technology to provide a plug-and-play experience, requiring minimal setup to start acquiring data.
One of the key features of the USB-TC01 is its wide compatibility with various thermocouple types, including B, R, S, T, J, K, E, N, making it versatile for different temperature sensing applications. The device boasts a high-resolution 20-bit Analog-to-Digital Converter (ADC), ensuring accurate temperature readings. The input range of ±73.125 mV and a maximum sample rate of 4 samples per second (S/s) are specifications that highlight the device’s capability to handle a broad spectrum of measurement requirements.
Accuracy is further enhanced by its cold-junction compensation, which has a typical accuracy of 0.6 °C and a maximum of 1.25 °C. This feature is critical for achieving precise temperature measurements in various environments. Additionally, the device includes overvoltage protection, with a maximum rating of 30 V between TC+ and TC-, safeguarding the device against unexpected voltage spikes.
Power efficiency is another hallmark of the USB-TC01, being USB powered with an operating current consumption of 150 mA and a suspend mode consumption of just 2.5 mA. This makes the device not only easy to use but also energy efficient. Its physical dimensions are 2.463 x 1.500 x 0.800 inches, ensuring that it is compact and portable, suitable for various field and laboratory applications.
