DC Current Transducer offers ambient temperature compensation.

Press Release Summary:

Housed in split-core package so existing wiring remains undisturbed, DT Series features temperature range of -20 to +50°C and provides 333 mVdc, 5 or 10 Vdc output proportional to DC current. With microprocessor-based method of signal conditioning, sensor output is automatically adjusted as temperature changes. DT Series is suited for applications such as measuring photovoltaic output in panels producing less than 50 A or less than 100 A, as well as monitoring smaller DC motors.

Original Press Release:

New DC Current Transducer Remains Accurate across Wider Range of Changing Temperatures

Greater simplicity and usability across PLC’s, DAQ’s and power management systems

SAN JOSE, CA – NK Technologies introduces the DT Series DC Current Transducer with ambient temperature compensation for increased usability and accuracy. The DT Series improved accuracy is due to a new patent-pending, microprocessor-based method of signal conditioning –  sensor output is automatically adjusted as temperature changes (e.g. installers do not need to add algorithms to adjust output as ambient temperature varies), eliminating one of the primary issues with Hall Elements-based products. The added signal conditioning can also eliminate the need to heat/cool the control equipment encloser, reducing considerable expense.

The DT Series is ideal for applications such as measuring photovoltaic output in panels producing less than 50 amps or less than 100 amps, as well as monitoring smaller DC motors (used in conveyors and other material positioning equipment) and electrical heaters. Key features include:

• Temperature range: -20°C to +50°C

• 333mVDC, 5 or 10 VDC output proportional to DC current

• 5 VDC or 12 VDC powered

• Monitors circuits of 600 V or lower

• Housed in split-core package so existing wiring remains undisturbed

• “Finger-safe” power supply and output terminals

• Simple two-screw panel mount or DIN-rail brackets

• Safety standards: Designed to UL508,CE standards

NK Technolgies has filed for a patent on the DT Series circuit design, and plans to offer the temperature compensation feature in its other DC current transducers in the future.


Founded in 1982, NK Technologies designed the first low-cost solid-state current sensing technology that underlies the industry today. 

Today, NK Technologies  is a leading provider of current sensing, ground fault detection and power monitoring products to the industrial and factory automation markets, with a product portfolio that includes more than 1300 models to satisfy a wide range of specific application needs.  As the needs of these markets change, NK Technologies is well-positioned to respond with sophisticated new product designs and improved product functionality necessary to meet those applications.
