Measurement Computing Corporation has announced the release of two Web-enabled temperature input devices, the WEB-TEMP and the WEB-TC, which allow users to take measurements and monitor them via the Internet. The new products, modeled after MCC’s popular USB-TEMP and the USB-TC products, have corresponding performance, but are Ethernet compatible with built-in Web servers that write temperature data to their own Web page for immediate Internet access from virtually everywhere!

“Besides the convenience of internet accessibility, these new Web modules are inexpensive, have excellent accuracy, and can literally be set up in seconds.” explains Jim Ficaro, Measurement Computing’s director of marketing, “When you type in the unit’s URL, the ready-to-use WEB-TEMP website opens to the temperature page—an environment that lets you select units, set alarms, and configure sensors from your browser. No application development required.”

The WEB-TEMP provides eight temperature input channels, each supporting all of the common temperature sensors (J, K, R, S, T, N, E, and B thermocouples; 2-, 3-, or 4-wire RTDs; thermistors, and semiconductor temperature sensors), and 8 bits of digital I/O. Each channel of the WEB-TEMP is capable of monitoring any of the supported input types, so users can mix and match the sensor to the measurement without additional signal conditioning. Moreover, the internal measurement electronics accuracy of the WEB-TEMP vastly exceeds the accuracy specifications of the temperature sensors, thereby recording the most accurate data possible. The WEB-TC specifications are similar to those of the WEB-TEMP, but support thermocouple sensors only.

All eight WEB-TEMP (or WEB-TC) inputs have 500 VDC isolation to the power supply and Ethernet port, protecting both the computer and the input device from damage.
The WEB-TEMP and WEB-TC ship with an impressive array of software included in the MCC DAQ Software CD. The disk includes applications, drivers, and libraries that meet the needs of programmers and nonprogrammers alike.
