SAN JOSE, CA – August 2018 – NK Technologies ( released the AGT-FD Series, new ground fault sensors that detect faults to earth from 0 mA to 100 mA and produce an output signal of 0–10 VDC in proportion to the amount of current passing to ground. The output is equal to the RMS value of the earth leakage. The AGT's sensing window is large enough to monitor 100 amp circuits. It can also be used to measure and monitor any low-value AC circuit current by passing just one of the conductors through the sensing window.

The AGT-FD Series is ideal for monitoring earth leakage current for applications including: electric heating processes, AC motor loads, semiconductor wafer fabrication, plastic molding processes, heat trace cable systems, and snow melt protection.

Features include:

  • Analog output signal, 0–5 or 0–10 VDC proportional to 0–100 mA
  • Externally powered, 24 VAC or DC(20-30V)
  • Factory calibrated, warrented to stay accurate for minimum of 5 years
  • Panel mount or simple snap onto DIN rail


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
