Instrumentation: Eight input channel USB devices
Measurement Computing Corp. released two 8-channel USB analog input devices, the USB-TC-AI and the USB-Temp-AI, featuring four differential temperature inputs and four differential or single-ended voltage inputs with programmable gain. Modeled after MCC’s USB-TC and USB-Temp products, which have all eight input channels configured for temperature, the AI versions are said to fill a gap in the test and measurement community for accurate temperature and voltage measurements on a single USB device.
The TC-AI and Temp-AI support J, K, R, S, T, N, E, and B type thermocouples and input ranges are
Both the TC-AI and Temp-AI have an integrated cold junction compensation sensor for thermocouple measurements. The Temp-AI also has built-in current excitation sources for resistive sensor measurements. They ship with an array of software included in the MCC DAQ Software CD. The disk includes out-of-the-box applications, drivers, and libraries for programmers and nonprogrammers.
