True RMS Current Transducers from Heaters Controls & Sensors

CR4110/4120 Series True RMS Current Transducers and Transmitters are designed for applications where AC current waveforms are not purely sinusoidal. More precise and accurate than other transducers, these devices are ideal in chopped wave and phase fired control systems.

CR4110/4120Series True RMS Current Transducers and Transmitters monitor AC current and produce a calibrated 4-20 mA or 0-5 V dc output signal.

CR4110/4120 Series True RMS Current Transducers and Transmitters operate over frequency ranges of 20 to 5K Hz and are available in seven different input ranges. In addition, external current transformers are available to extend the measurement range. Response time is 250 ms and the MTBF is greater than 100K hours.

A unique design feature of the new CR4110/4120 Series True RMS Current Transducers and Transmitters allows mounting on 35 mm DIN rails or they can be surface mounted with #5 screws.
