Signal converter series: 5 amp or low voltage to 4-20 mA
NK Technologies' CTC Series Signal Converters allow users to convert a CT Signal to a standard 4-20 mA two-wire, loop-powered signal easily.
NK Technologies' CTC Series Signal Converters allows users to utilize an existing standard 5 amp secondary CT or low voltage (0.333 V ac) ProteCT current transformer with non-contact ranges as low as 0-5 amps over a conductor to produce a standard 4-20 mA two-wire, loop-powered signal.
With DIN rail mounting and a 24 V dc loop-powered supply, the CTC series provides simple snap-in installation that requires no calibration because the primary current transformer ratio provides the scaling required without any installer intervention.
In some applications, such as monitoring a high voltage system, using a two-piece solution consisting of a current transformer and separate signal converter works better than using a one-piece sensor. A two-piece solution is also a better choice when the system is supplied with bus bars, making installation of a standard NK Technologies one piece current sensor over the conductor extremely difficult or even impossible.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
