Measurement Computing Announces USB Temperature Modules
Norton, MA - Measurement Computing released two 8-channel USB analog input devices, the USB-TC-AI and the USB-TEMP-AI, which feature four differential temperature inputs, and four differential or single-ended voltage inputs with programmable gain. 
"These new ‘AI' versions of our USB-TC and TEMP products fill a gap in the test and measurement community for accurate temperature and voltage measurements on a single USB device," explained Jim Ficaro, Measurement Computing's marketing director. "Flexibility and high performance at a good price."
The USB-TC-AI temperature channels support J, K, R, S, T, N, E, and B type thermocouples. The input ranges for the four voltage channels are software programmable for ±10 V, ±5 V, ±2.5 V, ±1.25 V.
The USB-TEMP-AI supports the same thermocouple types as the USB-TC-AI, plus RTDs, thermistors, and semiconductor temperature sensors, and has the same voltage input ranges.
The USB-TC-AI and the USB-TEMP-AI are USB 2.0 full-speed, modules supported under current popular Microsoft Windows operating systems, and are both fully compatible with both USB 1.1 and USB 2.0 ports. Separate, 24-bit analog-to-digital (A/D) converters are provided for each pair of analog inputs. And, both devices, in addition to the temperature and voltage input capabilities, provide eight independent, TTL-compatible digital I/O channels to monitor TTL-level inputs, communicate with external devices, and to generate alarms. The digital I/O channels are software programmable for either input or output.
Both the USB-TC-AI and USB-TEMP-AI have an integrated cold junction compensation (CJC) sensor for thermocouple measurements. The USB-TEMP-AI also has built-in current excitation sources for resistive sensor measurements.
The USB-TC-AI and USB-TEMP-AI ship with an impressive array of software included in the MCC DAQ Software CD. The disk includes out-of-the-box applications, drivers, and libraries that meet the needs of programmers and nonprogrammers alike.
