Differential pressure sensors
A differential pressure sensor has been added to its variable frequency drive and building management systems.
Taco has added a differential pressure sensor to its line of hydronic system components. The sensor relays system performance information to a variable frequency drive (VFD) or to a building management system (BMS). The Taco DPS629 monitors differential pressures of air and compatible gases and liquids. The design uses dual sensors that convert pressure changes into a standard 4 to 20 mA output signal for two-wire circuits. Its small size and few moving parts make for exceptional response time and reliability. Terminal block, zero, and span adjustments are easily accessed under the top cover. Designed to meet NEMA 4x (IP66) construction, the unit is applicable for flow elements, heat exchangers, filters, pumps, and coils.
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.
