Large Aperture Transducers facilitate dc current monitoring.

Press Release Summary:

DT Series combines hall effect sensor and signal conditioner into one package for use in DC current applications up to 1,200 A. Available in factory calibrated ranges that facilitate operation while also eliminating zero and span pots, large aperture current transducers offer 4-20 mA, 0-5 Vdc, or 0-10 Vdc outputs that are magnetically isolated from input for maximum safety. While internal power regulation delivers reliable operation, DIN-rail mount enclosure facilitates installation.

Easily Monitor DC Current with New DT Series Current Transducers from NK Technologies

Large aperture design makes it easy to seamlessly monitor any circuit up to 1200 amps

SAN JOSE, CA - NK Technologies introduces DT Series Large Aperture Current Transducers. The DT series combines a hall effect sensor and signal conditioner into a single package for use in DC current applications up to 1200 amps. Factory calibrated ranges simplify operation and eliminate zero and span pots. Industry standard 4-20mA, 0-5VDC or 0-10VDC outputs are magnetically isolated from the input to provide maximum safety, and eliminate insertion losses. Internal power regulation delivers reliable operation and helps keep installation costs low, even in applications with unregulated power. A DIN-rail mount enclosure makes installation easy.

"DT series current transducers provide design and process engineers with a rich source of equipment information," says Philip Gregory, President, NK Technologies. "They are economical and reliable tools for monitoring equipment status, detecting process variations and enabling corrective action to be taken before a failure occurs, and ensuring personnel safety."

The ability to monitor any circuit up to 1200 amps makes DT series large aperture current transducers ideally suited for any number of applications, including:
  • Monitoring load and charging currents, and verifying operation, of battery banks
  • Measuring traction power or auxiliary loads in transportation applications
  • Monitoring DC powered motors in cranes, saws, sorters and positioning equipment
  • Measuring the current produced or consumed, and detecting mechanical problems before a failure occurs, in wind and solar power generation applications

    Test and evaluation units are available to OEMs at no cost.
