Economical power monitoring devices
Siemens Industry's new line of Siemens Sentron PAC power monitoring meters ranges from traditional basic monitoring to intermediate power quality monitoring capabilities. They have bright LCD screens and can be configured through menus on the front or using free software for remote configuration. This is an October Control Engineering North American edition Product Exclusive.
Siemens Industry Inc. introduces the new line of Siemens Sentron PAC power monitoring devices. This cost-effective line of meters ranges from traditional basic monitoring to intermediate power quality monitoring capabilities. The meters have bright LCD screens and can be configured through menus on the front or using free software for remote configuration. They meet all ANSI/ UL/ IEC requirements for safety and accuracy. The PAC3100 meter is an “amp volt plus” meter. Designed to replace analog and amp meters, it also offers advanced features, such as Modbus RTU communication, a large display, and KVA/KVAR monitoring capabilities. It measures import and export energy and 25 other parameters. It is well-suited for sub-billing or cost allocation in commercial or industrial applications. When combined with supervisory systems, the meter cost effectively meets government EPAct and LEED requirements. It measures over 50 parameters and has a faster sampling rate for applications that require information about the state of the electrical system. Multiple communication protocol capability makes it a good choice for commercial and industrial systems. Optional communication modules for Modbus RTU and Profibus DP and can receive data from two independent supervisory systems—the Modbus TCP and the Modbus RTU. It enables users to set limits or alarms for voltage, current, power factor, and frequency. The PAC3200 does not require transformers when used with systems of 690 or fewer volts and offers a 22-65 V dc control power version for industrial systems with 24 V dc control power circuits.

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.
