Current Loop Fundamentals. Using Current to Transmit Transducer Data. Industrial-grade transducers commonly use current signals to transmit data. This is in contrast to most other transducers, such as thermocouples and resistive strain gages, which use a voltage signal.While voltage-based transducers are sufficient in many environments, current-based transducers are at times preferred.

Recall from motion design fundamentals that ac drives work on the principle of switching line voltage to run a motor. This switching causes a fluctuating current draw on the line which in turn causes a broadcasting of RFI and EMI noise back on the ac motor drive input line. A filter can attenuate the draw to eliminate the noise.

Steps 1 and 2 should be repeated until the center of your conveyor belt is within a quarter inch of the tail pulley's center. Be careful not to make any large adjustments. A small adjustment can make a huge change. Make sure to start with the snub rollers closest to the ends of the conveyor and work your way towards the center.
