NK Technologies Presents AT/ATR-TH Series Current Transducer in Triple-Aperture Solid-Core Design

Press Release Summary:

The AT/ATR-TH Series Current Transducer is designed for monitoring three-phase loads, motors, machines, and buildings. The device can detect open discharge lines, clogged filters, or blocked intake to pumps in water delivery and treatment systems and over/under current conditions. It is powered externally with 24 VAC or DC (22–18V) and provides a choice of 0–10 to 0–200 A. The sensor mounts on a back panel or a DIN rail and can accommodate wire sizes for loads up to 200 A.

Innovative Triple-Aperture Design of AT/ATR-TH Series Current Transducer from NK Technologies Makes Monitoring Three-Phase Loads Easy

SAN JOSE, CA – The AT/ATR-TH Series Current Transducer is the latest innovation from NK Technologies for monitoring three-phase loads, motors, machines, and buildings. The large triple-aperture solid-core design allows for quick installation – conductors thread easily through the sensing windows (apertures) and reconnect on the other side.

The transducer outputs are powered from an excitation voltage of 24 VAC or DC, or optionally 120 VAC, isolated from the monitored circuit. Three outputs are proportional to the AC current in each phase and a fourth represents the average of the three. Each are available at any time. The sensor mounts on a back panel or a DIN rail and is designed to accommodate wire sizes for loads up to 200 amps.

Applications include:

  • Detecting over/under current conditions before they cause breakdowns in large machinery or interlock one process with another.
  • Detecting open discharge lines, clogged filters, or blocked intake to pumps in water delivery and treatment systems.
  • Monitoring motor current draw, which should be nearly equal in all three phases. (A difference of 10% or more signifies trouble.)

Key features:

  • Analog signal proportional to AC current; both average and True RMS models available
  • Choice of ranges: 0–10 to 0–200 amps
  • Externally powered, 24 VAC or DC (22–18V) or optionally 120 VAC
  • Factory calibrated, warranted to stay accurate for five years minimum
  • Snap onto DIN rail or attach with screws to a panel for secure mounting
