Current Sensors

CTA2 Series Analog Current Sensor

The CTA2 series output analog current sensors are designed for use in any AC current monitoring application to monitor a particular piece of equipment.

Overview

The CTA2 series 4-20 mA output analog current sensors are designed for use in any AC current monitoring application to monitor a particular piece of equipment. The “Average” style current sensors should be used in applications where the sinusoidal waveform has no distortion or noise on the conductor being monitored. Applications of current sensors may include monitoring a resistive type load such as an incandescent light bulb, heating element as well as any single speed linear load. “True RMS” sensors are able to be used in all applications since the “True RMS” current sensors provide the best overall accuracy and should be used in applications which includes variable frequency drives, switching power supplies, computers and data centers, electronic ballasts, SCR’s, and variable speed loads.

The current sensors are available in both solid and split-core versions which also includes a patented (Pat. No. US 7,416,421) 35 mm din rail mounting foot for easy installation in panel mount applications. The solid-core versions are a great choice for new installations or OEM applications in which cost sensitivity, lower trip points and environmental issues like dust and moisture may be of concern. The split-core version of the current sensors work great in retrofit applications and for use on service technicians vehicles since one or two parts will work in most applications and can be easily installed without disconnecting any wires. Applications of analog current sensors includes load trending, basic power monitoring, electronic ballasts, computers/data centers, industrial, variable speed loads, pumps, compressors, fans, preventative maintenance, LEED, project justification (ROI) process control, solid state environments (SCR’s).
