NK Technologies Selecting the right transducer: VFD and SCR output waveforms are rough approximations of a sine wave. There are numerous spikes and dips in each cycle. ATR transducers use a mathematical algorithm called "True RMS," which integrates the actual waveform over time. The output is the amperage component of the true power (heating value) of the AC current waveform. True RMS is the only way to accurately measure distorted AC waveforms. Select ATR transducers for nonlinear loads or in "noisy" power environments.

Selecting the right transducer can make or break your project. Check out the comprehensive NK Technologies Application Guide, and let us help you make the right choice!!!
