USB Analog Input Devices measure temperature and voltage.
Press Release Summary:
Supported under Windows® OS, USB-TC-AI and USB-TEMP-AI are USB 2.0 modules featuring 4 differential temperature inputs and 4 differential or single-ended voltage inputs with programmable gain. Model USB-TC-AI's temperature channels support J, K, R, S, T, N, E, and B type thermocouples, and USB-TEMP-AI adds support for RTDs, thermistors, and semiconductor temperature sensors. Input ranges for voltage channels on both models are software-programmable for ±10, ±5, ±2.5, and ±1.25 V.

Two New 8-Channel Analog Input Devices Feature Accurate Temperature and Voltage Measurement
NORTON, Massachusetts-July 23, 2007-Measurement Computing Corporation, a market leader in low-cost data acquisition, today announced the release of two new 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 products are modeled after MCC's highly successful USB-TC and USB-TEMP products, which have all eight input channels configured for temperature.
"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.
