Temperature data collection device offers high signal isolation
New Ethernet measurement instruments from Data Translation use galvanic isolation to preserve signal integrity.
Data Translation, Inc. has announced two new ultra high-isolation Ethernet measurement instruments added to its Measurpoint product line. These devices take analog signals from temperature sensors and digitizes the output. The ISO-Channel design provides up to ±3,500 V high voltage rejection using galvanic isolation techniques to preserve small signals generated from thermocouples, RTDs, and other sensitive sensors in harsh, high voltage noise environments. Wind, gas, battery, and solar energy installations are just a few industries where high-isolation protection is required to ensure data acquisition integrity in noisy and often remote settings.
Key design features include:
• High isolation to earth ground: ±1,400 V continuously or 2,500 V for transients (DT8875) or ±3,500 V continuously or 5,000 V for transients (DT8876)
• Channel-to-channel isolation: 2,800 V (DT8875) or 7,000 V (DT8876)
• High stability, 24-bit resolution, Delta Sigma Adc per channel
• Up to 40 simultaneous differential inputs (DT8875) or 20 simultaneous differential inputs (DT8876)
• Measure thermocouples, RTDs, or voltage, and
• Sample up to 10 Hz per channel.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
