NK Technologies: Current Sensors
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. The sensors include an 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 2-100 percent of the analog range and can be verified at any time by viewing the LCD display on the sensor.
