Accurately measure sinusoidal, distorted, or pulsed current wave shapes without additional hardware and its associated costs and space requirements
NK Technologies introduces the ATH Series AC Current Transducer. The ATH is specifically designed to monitor power controlled by phase-angled fired, burst fired or time proportioned silicon-controlled rectifiers (SCRs) in heating applications, without requiring an external current transformer or shorting blocks. Patent pending Time Integration functionality incorporated in the ATH design provides an output signal directly proportional to the RMS amperage to ensure accuracy regardless of the AC current wave shape. The sensor samples the AC current continuously, updating its own time base when the current returns to the load after a pause. Based on the magnitude of the burst and the time interval between bursts, the sensor output represents the amount of power used by the connected load.
NK Technologies’ flexible cable current sensors wrap around the conductor using very little space. The cable is connected to a signal conditioner located up to several feet away from the conductor, and produces an industry standard 4 to 20 mA signal in proportion to the AC current. With ranges of 0–500 to 0–2000 amps and frequencies to 400 hertz, the ATCR series is well suited for a wide range of applications.
