AC Current Sensors include built-in digital display.
May 14, 2014 -
Combining current operated switch and transducer in single package, ATS Series provides solid-state contact that changes state when current exceeds adjustable level or falls below normal running current. Built-in digital display delivers quick visual indication of where contact changes, enabling accurate setpoint adjustment. With NO or NC switch to control circuits up to 240 Vac, ATS models are compatible with most automation systems and offer choice of 4-20 mA, 0-5 Vdc, or 0-10 Vdc output.

SAN JOSE, CA — NK Technologies new ATS Series AC Current Sensors combine a current operated switch and transducer in a single package. A prominent feature to the new design is its built-in digital display that provides a quick visual indication of where the contact changes, making it the easiest and most accurate setpoint adjustment available.
These sensors provide a solid-state contact that changes state when the current exceeds an adjustable level or falls below the normal running current. This means reduced installation time, plus the option to have local control of a starter coil, while at the same time sending the analog signal back to a controller housed in a separate cabinet.
The factory set analog output calibration produces an accurate and stable signal by eliminating field zero and span adjustments. The trip point is adjustable from 2% to 100% of the analog range, and can be verified at any time by viewing the LCD display on the sensor. Any adjustments made by unauthorized personnel will be displayed, further improving overall system reliability.
ATS current operated sensors are advantageous over electromechanical pressure or flow devices by providing more reliable electronic proof-of-operation, while eliminating the need for multiple pipe or duct penetrations. ATS sensors are ideal for a wide range of industrial applications, including conveyor jam and overload protection, multiple conveyor section interlocking; pump control monitoring and shut down in the even of current rise beyond setpoint, cooling tower monitoring for time-of-use and clogged filter detection; grinder time-of-use and estimated power consumption monitoring, starter coil monitoring and machine shut down if an overload occurs.
ATS transducer/switch models provide a N.O. or N.C. solid-state switch to control circuits up to 240 VAC. Compatible with most automation systems, ATS models are available with a choice of 4-20 mA, 0-5 VDC or 0-10 VDC output. Each output offers a range that is proportional to either 0-50 A or 0-200 A.
