NK Technologies' AC Current Sensors indicates where contacts change
NK Technologies' 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. 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 a 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.
ATS sensors are engineered 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 event 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.
