Beckhoff
Automation
has released the new EL3681 and KL3681 terminals. By
integrating digital multimeters directly into I/O nodes, users can expect a
streamlined and low cost alternative to stand-alone digital multimeters. The
modules provide high precision and simple, high-resistance measurement from 300mV
to 300V and cost just $305.00 (U.S. list) each.
Using
the digital multimeter terminals with fieldbus interface for measuring current
and voltage, measured values can be processed directly in the I/O system or by
the master controller. These dynamic measuring terminals are available for both
the Beckhoff Bus Terminal system, which offers support for most major
fieldbuses as well as for the high performance EtherCAT® Terminal system.
Equipping
industrial systems with the Beckhoff KL3681 (Bus Terminal) and EL3681 (EtherCAT
Terminal) significantly increases flexibility thanks to the wide input range
and automated measuring range selection.
In
measuring applications, the expected voltage is often not known during the
planning phase. Automatic adjustment of the measurement range simplifies use
and reduces stock levels. Beckhoff's digital multimeter terminals measure dc
and ac voltages; in the case of ac voltage, the effective (RMS) value is
determined.
Very
high immunity to interference is achieved via the complete galvanic isolation
of the electronic measuring system and a measurement interval of typically 200
ms. The measured result is equivalent to that of a good hand-held multimeter,
but the I/O Terminals also have an interface to most major fieldbuses via which
it can be read out and parameterized.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
